Once in a great while, we have a series of events where our machines
with beam scanning functions in them will all be steered out of place
enough to trigger alarms and shut the units down.

It does take a lot of magnetic disturbance to force these out of
alignment, but there is no other equipment adjacent, on the roof nor in
the ground. This area of operations are on ground level cement slab and
the roof is tin with nothing but static vents. Power feed transformers
are far away.. There was no near by strikes which has never cause this
in the passed.

The strange thing is, we had to wait ~ 20 mins for a restart because
we kept on getting an error in steering, on all the machines, then it
finally cleared up..

All these machines are independent of each other..

Is there any geological events that can take place to cause this in the
ground or maybe solar charge of some kind? It's almost like some one was
hanging a large magnet over our plant.

Well, we are getting on towards the solar maximum of the current solar
cycle, although it continues to look as if this is going to be a
relatively modest solar-max. There have been a number of significant
solar flares in the past few months, and I've heard anectodal reports
of coronal mass ejections and the resulting geomagnetic storms which
were strong enough to trigger some significant auroral activity.

If you've been keeping records as to when these steering disruptions
have occurred, you could compare them with the geomagnetic-monitor
summaries of the planetary K index. If they seem to line up with
periods when the K index is 5 or above, then it's entirely possible
that your beams are "feeling" geomagnetic variations due to a big
cloud of plasma hitting the ionosphere after a CME.

ftp://ftp.ngdc.noaa.gov/STP/GEOMAGNETIC_DATA/INDICES/KP_AP/ has the K
index data, down to a 3-hour resolution.

For an interesting read, look up the great Carrington solar flare of
1859, and the resulting geomagnetic storm, and then consider the
probable effect on our modern civilization of another storm of this
magnitude.

Do your own fucking testing.

Eg:

1. A compass needle will respond to static variations in the local magnetic
field.

2. The trace on an analogue scope also responds to the local magnetic
field, be it static or otherwise - budget scopes have CRTs with no mag
shields.

I wouldn't know about budget scopes with CRT's, we only have one CRT
scope and that is at home base and it's a Tek 350hz model. The rest of
our scopes are all TFT/LCD, Regol, Tek and Lecroy and thinking about
getting an Agilent.

As for the compass needle, We use a flux differential array sensors
and that went very screwy.

storm - one that can literally fry all satellite electronics, and zap
almost all ground-based electronics?

They are. Or rather the planet has a pretty huge magnet inside it and
the solar wind can buffet it enough to cause trouble for sensitive gear.
More so in the US and Canada than in Europe since magnetic North is on
your side of the planet.

Any geomagnetic record for your neck of the woods would show if it was
from a CME event. This one goes back a few days

http://www.n3kl.org/sun/noaa.html

Place to look next time it happens.

You might want to make a simple magnetic disturbance monitor to
determine independent of your kit if there is a magnetic storm.

** Thanks Martin.

Despite the OP's staggering lack of insight, the motive for my two
suggestions re the magnetic compass and simple CRT type scope was the very
same idea.

I also suspect the notion alluded to in the heading is pure hogwash.

Rubbish. Dipole field falls off as 1/r^3.

They are not all that powerful at a distance. At least up to the sizes
used for magnetic clamps. You don't want one in a pocket though. I
became attached to a supermarket checkout till once after someone put
one in one of my pockets. They will nip flesh rather painfully - big
ones destructively. Didn't harm my bank card at all.

Superconducting NMR magnets are in a different league altogether. I know
of one where the outer shell has a dent from snatching the end of a
passing scaffold pole from outside the building.

Again you have to be quite close to magnetise the screen and any damage
is fairly local. The one thing I found did zap bank cards was the
initial power on degauss coils of big reference colour monitors in the
old days if you were leaning over or working on them at switch on.

There was a hefty boing noise from the coils responding to the degauss
waveform. That really did for bank cards if you forgot.

Trams? Large arc welding kit nearby.
Seen that destroy some early CNC kit after the machine went beserk.

Our magnetizer at work will erase those club discount cards that
stores give out if you stand within a few feet of it. I think it
makes a 1.3T pulse 150ms long with a coil ID of 8 inches. Never had
any credit cards get erased though.

solar flares cause massive disturbances to the earth's magnetic field.

Take a look at the Noise Floor of the Earth's Field:
<http://www.vlf.it/naturalnoisefloor/naturalnoisefloor.htm>
the field noise data cmoes ffrom actual meaurments of sites
From paper, here is its bibliography:

5_ M. Balser and C.A. Wagner, "Observations of Earth-ionosphere cavity
resonances", Nature, Volume 188, pp 638-41, 1960

Magnetic fields are insidious, once created you can't destroy them,
simply redirect them. And, low frequency are the worst, because they
penetrate EVERYTHING! Using mumetal can get expensive, and if not done
properly can easily exacerbate the problem by 'sucking' in magnetic
fields and actually intensifying them locally, so even that type of
shielding must be done carefully.

from those charts:
at 1 Hz the noise spectral density is 'normally' 1pT/rtHz, and it has
a 1/f distribution [I think]
at 0.01Hz it has climbed to over 1nT/rtHz.

If your e-beams are low speed, circa 10-20kV and the run path is long,
it doesn't take much field to deflect the beam over 100nm down at the
target, which in today's geometries is HUGE!

Has anybody produced the calculations for you? It should be part of
your equipment's performance spec - specifying the operating ambient
fields that are allowed. Then it'sup to you to prove your fields are
less than that.

Anyway, the number in those charts is 'average' which means during
solar storms it can easily go above 10X that value - for days! and
even into the 100X for short periods.

Do you have ambient magnetic field instrumentation monitoring the
fields? They are purchaseable items.

You have to find the frequency values of the disturbance, could be
related to a bad AC mains return cable going intermittent on you.
Those fields can get into the 100's of microTesla ranges and THAT will
deflect even an old monitor's traces.

Just thought of something, our satellite reception went wonky the
other night/day? during 'good' weather. The satellite company claims
moisture in the air during a rainstorm reduces the uWave signal and
you get signal breaking up. We got signal breaking up but the weather
here was SUNNY and clear! Anybody else experience that? Maybe we can
correlate the disturbances we saw to what happened to Jamie.

You have to switch them off, and let them cool for a while.
The degaussing coil is fed by some PTC / thermistor.

Shadow mask, I once dropped a color set, mask permanently bended,
no way could you get purity back.

I had a real degausing coil in the shop, huge coil, circle in front of the screen.
slowly move away, directly fed from main.

You can break the sat signal by running some machine that sparks,
say DC electric motor.
I have had total loss of signal when a thunder cloud passed between satellite and my dish,
while it was still sunny here (online rain radar show it).

Indeed. A colleaque of mine from Uni Genova told once how his
CRT computer screen bent and distorted like the clocks in the
"Persistence of Memory" every now and then, at the time his office
was above the big hall where some large magnets were tested. I think
those magnets were sections going to the Compact Muon Solenoid.

It can be worse. In the 1980's Cambridge Instruments sold an electron
beam microfabricator to GE in the US, to a lab on the east coast. The
installation was doing fine until it came to final acceptanace tests,
when the patterns being written onto the silicon wafters started
showing intermittent step shifts of about half a micron - 500nm - and
nobody could work out why.

In a final desperate attempt to solve the problem our senior engineer
was flown over to America. He was a technology history buff and was
impressed when he got to the GE lab - it was an old building, and the
lift they used to get him up the electron beam microfabricator on the
first floor was a real antique, dating back perhaps 100 years, which
relied on hydraulic pressure to go up and down.

The cylinder which formed the floor of the lift was a very large
chunk of magnetic iron. When the lift was at the first floor, it
changed the magnetic field at the electron beam microfabricator enough
to shift the beam on the specimen by 500nm.

The solution to the problem was not to allow the lift to move while a
pattern was being written. The electron beam microfabricator sold for
a couple of million dollars, so there was quite a lot of money hanging
on the correct diagnosis.

I was in work today and spent about 2 hours zeroing the sensor array
around each vault to get proper readings at the computer. What ever
happen the other day sort of corrected it self as for the E-Beam,
but the sensor array we have hanging around each vault did not fully
come back into zero alignment for what ever reason.

The sensors are something we constructed as a way to detect the
surroundings with in the critical areas of the E-beam to keep people,
metal objects and equipment from being place in proximity of the vault.

If you disturb the area around too much in the area where the E-beam
is housed, it will cause the beam to steer off and if bad enough cause
heating in the aperture, which isn't a good thing because it can also
cause .001" thick titanium window to heat unevenly and thus start a leak.

Heating of the aperture can propagate up the drift tube and bellows
which all have gaskets that leak when slightly aggravated.

So, we try to force the system to shut down at the slightest hiccup so
there won't be hours or lost time and repair work.

The message I get is "There is no response from the news server, check

When this happens, if I hit the send again, then most of the time it'll
work, but some times it may do a time out again.. It's very frustrating
because this software does not seem to have parameter to set the time ou

Do all of your employees know about the fact that they should not have
anything magnetic on them? I mean all, includings secretaries, janitor

Reason I say that is that there are people who believe that slapping
magnetic patches onto aching joints or other body areas has a healing

The education and common sense level of those that apply for jobs
these days are amazingly low. But we need to have business as usual.

There is generally no problem with those that operate the equipment,
it's those that aren't usually in that area, like material handers,
brain dead salary, people on tour and the general no nothing grease
monkeys and contractors.

The best one's are the truck drivers when they drop a load or back
straight into a vault wall. Cracks in the containment walls are not
generally a good thing.

The magnets they use for that are usually the rubber, refrigerator type
that are barely magnetic. I can't imagine they will mess up this
equipment unless they are pretty close to it. I assume the vault itself
has restricted access.

One of my friends used to sell magnets for health. She claimed that she
cured people with them and truly believed in them. They cost a lot of
bucks too and were pretty worthless magnets. It is amazing how easy it
is to fool otherwise intelligent people with a little techno-babble.

There are many ways to carry out a beam scanning function, so this
isn't really a good way to describe the nature of the victim
equipment. Is it microwave radar, laser, atomic particle - what type
of beam technology is being disturbed?

The different units may be independant, but they will still share
power and probably communications. If they are directed at the same
target, this is also a common factor. If they run on the same
software/firmware revision, in the same time zone, that's also a
commonality. The longer-term effects suggest SW that is not
particularly error tolerant.

If the 'flux differential array sensors' that went screwy at the same
time were indeed multiple and independent of the misbehaving
equipment, then it might mean something. If they're just parts of the
misbehaving equipment, their output is meaningless.

IMHO the best diagnostic avenue is a makeshift "magnetic pulse catcher".
Could be made with a scope that triggers upon exceeding a prescribed
good-bad band. The Instek GDS-series has that, at least my GDS-2204
does. In this case meaning it'll trigger when the normally flat
horizontal line wiggles either way. Hang a loop with burden resistor
onto it and wait until the next event. There would be a recording
afterwards. The shape of the pulse should give some good pointers of
what it could be. For example, if you see a brief burst of 60Hz cycles
you'd know :-)

Just a thought, in case you guys haven't purged the facility of larger
CRT monitors: Those have degaussing coils. Some come on every time their
power is cycled, others come on at random. Fridge de-icing loops can
also cause some grief because sometimes they consist of a somewhat
resistive wire run around its door frame, meaning a loop many feet in
diameter.

You enjoy talking in riddles it seems.

Difficult to comment sensibly without knowing what sensor technology you
are using and whether or not active shielding is involved.

One possibility is that one of your machines is going haywire and taking
the rest down. Or you are being affected by externally sourced radio
frequency interference that is wrecking the beam steering.

I presume the application is electron beam lithography but it would make
it a lot easier if you clarified this. Synchrotron radiation sources
also use electron beams as a means to an end.

Why are you so coy about describing what sort of kit it is?

An academic institution would by now have a simple crude primitive
magnetic field disturbance detector knocked up out of fishing line a
mirror and a magnet. Laser pointed at the mirror and the whole assembly
protected from drafts with a glass tube. Simples.

Sophisticated gear can have complicated modes of failure. At present you
have no idea what caused your stuff to go AWOL and the way you are going
you will be every bit as mystified the next time it happens too.

We have inductive loops attached to the walls, spaced closely to form
an array. These loops are all driving via Atmega processors to generate
a pulse and fast compactors attached to the inputs.

They daisy chain together and the end unit will connect via serial to
the PC.

The program in each does not generate its own ID however, the values
for each zone are appended to a packet and the size of the packet and
CRC are recalculated. We have an input assigned to the uC indicating
it is the first unit via jumper, so it'll start TXing immediately and
the others will wait for a packet to arrive and then send it to the
next, etc.

The first unit will pause sending for the maximum time it would take
all 16 devices to send if they were implemented or if some error
resulted in the link some how.

With this kind of configuration, you are able to see moving objects as
they pass by the wall.

We don't use a BFO method because it is far to unstable but found that
using time constant on L works very well. The mosfet switches are used
to energize the coils. THe gate is driven via a bjt from the uC for the
on state and for the off state a pull down R is present at the gate to
allow for a slow turn off, we did this to avoid the wheeling voltages
and not use diodes, so far it seems to work


I use the atmega due to high IO count, so each uC can accumulate many
zones which will keep the lag down.

Also to add to that, when sampling in the group of IO's we need to
stagger loops, meaning, we can't energize a loop adjacent for obvious
reasons.

There are other little details we do with this system but I won't get
into that.

The E-beam processing is far from any form of known electrical
disturbance and it's housed in its own building attached to the main
structure..

Long before I was there, it was required it had to be built on a
cement slab to insure nothing below it was there. In the main building
we have transformer vaults but nothing goes under this building for the
E-Beam. Also it had something to do with environmental laws.

We are located in the center of CT, Northeast US.. I know Maine just
recently had an earth quake but as for as I know, we had no issues with
that here. Actually, the only think that happen was my dog getting
scared of something at the time it happen and insisted she had to come
in. I let her in and I noticed her tail was between her legs, she was
afraid of something, I had no idea what it was at the time.

There was reports of ground shakes, I didn't feel anything myself,
most likely too wrapped up with other things :0

Ha, quit.

It does not take much to whack out the system from the top side of
the vault, it's not protected that well and is cordoned off when in
operation.

I suppose some atmospheric abnormally could disrupt it. I know near
by strikes from
T showers does nothing to it, at least not enough for it to get
spassed out.

Talking about pumpkins, I stopped at a place today and got talking to
the clerk and he mention how he has this young labrador mix, he let him
out side for a bit and the lab chewed up half of the pumpkin he put the
the steps.. So any one that has dogs, beware, I guess some of them like

Try downloading data from the USGS National Geomagnetism Program at:

Skimming the various strip chart graphs shows some rather radical
short term variations. Where are you and what was the date and time
of the event so I can play with the numbers? Looks like the real time

This happen in the middle of last week.. and I did check one of those
sites. As best as I understood it, it does look like some red hot spot
was over our area just about at that time. That is, if I read the image
and data correctly.

It's really weird and not the first time this has happen.

But, can't let that get in our way, even though it force a lot of work
on the machine operators to pull back the product they were running
though it to make sure it got a proper dose. Some of the products run
through it takes 2 people just to pick up one end.

I thought you were doing wafer fab, not electron beam welding.

Looks like you're on the east coast. Virginia would be the closest
observatorium:

Argh. The GIF files are generated on demand. If you get garbage
instead of a graph, just get a cup of coffee, hit refresh, and it
should be there. For Oct 24th. Ugh, I can't tell which is the
correct day, but they both have the same dip:
<http://geomag.usgs.gov/wwwplots/frdt-5.gif>
<http://geomag.usgs.gov/wwwplots/frdt-4.gif>
Looks like some kind of event at 1PM UTC, which would be 8AM EST.
However, the intensity variations (H field) of 50-75 Newtons doesn't
seem to much different from any other days variations.

Checking if it's the moon:

Nope. On Oct 24, the moon was below the horizon for most of the day.

Ok, so were there any crop circles on the lawn, missing secretaries

hell no, we do cross linking of insulating materials. Other people
use the same type of equipment to irradiate food, tires etc...

I don't know how much energy is involved with wafer fabrication but
we can go up in the range of 2.5 Mev on a couple of the machines with
a large scanning area. One of those machines are fed with paired 750MCM
feeds from the buss, that is each phase has a pair of 750MCM, the other
machines use paired 500MCM

We met up with some one about 5 years ago now, that has a unit that
requires a dedicated feed from the electric company, lots of power
there. They irradiate anything for any one accept petroleum, that is
done with a proton accelerator.


We do custom electronics for other operations in the business too,
everything we do stays in the circle of the company. We do not
design anything for commercial applications out side of what we do there
or what ever one of our other locations may need.

Out side of that, I do get into designing electronics that is not
related to my job. The last big adventure I got into was redoing an
eddy current heat treating process inverter system, that was fun. snack
toy money.

Egads, a major power user. It's going to take a rather large magnetic
field to move such a high power electron beam. I was thinking in
terms of electron beam lithography in a wafer fab, which is probably
more sensitive to magnetic fields than your monster.

Well, maybe a CME (coronal mass ejection) landed some charged
particles on your wiring adding a DC component to whatever you're
using to feed the ray guns. It wouldn't take much DC on the power
lines to create a magnetic field inside the building:
<http://www.spaceweather.com/archive.php?view=1&day=24&month=10&year=2012>
Well, there was a solar flare on the 23rd, but no CME. Ok, I give up.

E-beam wafer fab work doesn't involve a lot of energy. It's just
exposing an electron-sensitive resist, typically for less than a
microsecond. The standard Cambridge Instruments set-up was built
around their S-250 electron microscope, which only went up to 40kV -
there was some interest in getting it up to 100kV, but I don't know if
it got anywhere.

While you gained from the finer focus, you lost from the spread of the
high-energy secondaries in the silicon under the resist.

It's not power that matters, but voltage. The faster the electron is
travelling, the harder it is to bend it's path.

And you bend the path of each electron by the same amount. A moving
electron does constitute a current, but not a large one.

We didn't have any issues with the electrons impacting on a non
intended target. It was a problem with the aperture heating up due to
some disturbance that forced the steering out of alignment enough to
abend the system. On top of that, it saturated the sensor array we have
attached on the out side of the protected vault walls.

btw, we have a storm coming in on us and they called me this morning
to notify me of them canceling operations at our facility. So i'll be here
to aggravate every one, including you.

True but, the units we have do not all come off the same transformers
and they are located far from the location.

Even though we are generating lots of energy, still does not actually
take that much to move the beam, when the train passes by behind the
building we can notice a slight shift in the machine that is closes to
the tracks, steering is critical. On the original machine, which is
still in operation, focus coils have been added but not for focusing and
a couple of small permanent magnets are position just above the scan horn
to correct for an obstruction in the structure so the beam will scan in
a straight line.

We are thinking of using a DDS type system to generate a AB pattern so
we can create custom steering for problems like these. The manufacture
of the machines told us they once tried to engineer a multpoint ramp
signal generator ref for the scan amps but didn't have much success with
it at the time. I guess they had an array of 10 turn pots to set each
point into a summing circuit from a digital IO mux chip.

Playing with present DDS technology at the board level would be a
first for me ;)

Have a good day.

I don't do that with the loops but the fluxgate detectors was considered
however, research indicated that they may not have been that good at
detecting pedestrians and we ended up with what we have.

We can't put anything sensitive inside the vault, it'll get destroyed
with in mins, maybe seconds with electrons bouncing off the walls like
they do. As it is, we have problems now with an acid that builds up on
everything due to the ozone generation and moisture mixed.

I had the problem while trying to trim hybrid resistors with a sand
blaster and later a laser. Besides the earthquake simulating
vibration from the passing trains, there was the slight tilt in the
concrete slab foundation when the train was parked near the building.
The weight of the train would cause the foundation to tilt, ruining
the laser alignment. I found the problem by setting up an optical
(non-laser) tilt measuring contraption using a distant mountain top
reference point. Actually, that was a marginal idea because I found
myself measuring tides and freeway traffic. When the number of cars
on a nearby freeway increased during rush hour, the ground would sink
sufficiently to deflect the inclinometer. However, it did demonstrate
that train induced foundation tilt was the primary culprit.
Speculation was that the building was floating on the water table, but
that was never proven. Until the system was rebuilt to be less
sensitive to building movement, we posted the train schedule on the
wall, and production arranged to have breaks when the trains were
scheduled to pass.

My sense of smell tells me that the problem has something to do with
the utility power, but exactly what and how, I can't deduce. Are you
doing any monitoring of the DC component of the utility power? Perhaps
even order harmonic distortion, which would show up as a change in
waveform symmetry?

Isn't it true that if you generate carbon monoxide that its presence

Interesting. We did the same thing, but with these:

https://de.wikipedia.org/w/index.php?title=Datei:Solingen_MAN_SL_172_HO.jpg&filetimestamp=20070923163037

In order to perform accurate ultrasound beam profile tests we had to
wait until each bus was at least 1/4 miles down Beethoven Street. I was
amazed how heavy and "ground-moving" electric buses can be. This was in
Germany where most passengers on these buses are not members of the
0.1-ton class.

No I have not done that but like I said, the feeds come in a long ways
from that location plus we have our own transformers. If memory serves
we have 12kv lines coming in to our transformer stations. We have 2 out
side and 5 transformer vaults in the basement of the main building. But
like I said, they are far way, if there was that sort of issue I think
we'd see problems in other equipment.

I'll tell you what happen one day though, non related to this thread
here, was a general inspection was being done of the 12kV feeds coming
in out side from the electric company, something that is done by one of
the E1's there. He was out side looking up at a commercial feed coming
in and noticed a connecting link to our building was dangling? how could
this be? That would mean we're single phasing however, the plant was
fully loaded as normal.

It was strange, we started to doubt how our place was wired, because
we have another feed coming in. After remembering conversation a I over
heard about the third shift electrician making a comment about one area
having a voltage issue and he couldn't figure out, it all clicked in and
we all seem to agree with that. What was happening was, with all the
induction motors we have operating, they were generating the third leg
for us..

Never thought of that at all!

I could experiment with too. [I asked them to come take it away, but
they said they don't do that.]

A crude way of testing for DC on the AC mains is to find a cheap
magnetic compass, and put it near the AC lines. It it's stuck
perpendicular to the line, at any position, you have DC. If it
wanders around, or points in generally the correct direction, there's
no DC component. (Note: This doesn't work if the AC cables are run
closely parallel to each other).

If it happens again, have a magentic compass handy.

Rotating power transfomers. Nice.

Reminds me of a technician of mine. Before he worked for me he worked
for GM in Michigan. One morning, at dawn, driving to work in a nasty
snowstorm he hit a frost heave hard and lost a hub cap which went
sailing off on down the highway.

A mile or so down the road he's waved down by a woman, hysterical,
"her windshield had been hit by a flying saucer" ;-)

I love to cook with wine. Sometimes I even put it in the food.
