I found the valve only yielded 4 watt power so I'm designing a transistor
oscillator of the same frequency of ~2 MHz.

I'm using two power transistors of 100 watt each it should yield 200 watt.

If my method is correct Poynting's vector inside the coil will be
200/4.9E-4=407000 watt /m^2 so the E-field will be given by:

<S>=(e0c/2)E^2 = 132.7x E^2 so E=SQR(407000/132.7)=55.38 volts/meter.

So for collision energy near windings,

40=m f p x 55.38 so m f p = 72 cm. That corresponds to a pressure of 10^-5
Tor.

I should be able to ionize the hydrogen in this tube.

Near the axis the field will be 13800 volts/meter so the collision energy
will be m f p x 13800 = 1 x 13800 or 13.8 KeV
This corresponds to a temperature of 2.2E11 K or 1100 times hotter than the
sun's core. Hot enough for proton fusion.

I have a problem with biasing by circuit at present but the new bias
resistors should arrive on Friday. The hydrogen tubes will not be delivered
until after thanksgiving.

This theory assumes that the windings of the coil act as an antenna sending
waves towards the axis and concentrating the energy as it approaches the
axis.

It is like the interior of a cylindrical mirror focusing the radiation at
the center.

The oscillator I built turned out to have a power of only 12 watt. So it did
not work.

I think I was able to obtain a Townsend discharge because the tube became
warm but it did not glow.

I think I need 1 KW for the effect I'm looking for.

At present I'm looking for a 1 KW oscillator that I can get a professional
to build.

The power supply and the oscillator are up for sale as parts as they only
clutter the place up.

If no one buys them they will end up in the skip.
