Exploiting the energetic interaction of intense femtosecond laser pulses
with deuterium clusters, it is possible to create conditions in which
nuclear fusion results from explosions of these clusters. We have conducted
high-resolution neutron time-of-flight spectroscopy on these plasmas and
show that they yield fast bursts of nearly monochromatic fusion neutrons
with temporal duration as short as a few hundred picoseconds. Such a short,
nearly pointlike source now opens up the unique possibility of using these
bright neutron pulses, either as a pump or a probe, to conduct ultrafast
studies with neutrons.

Thank you for this information. I can use it in calculations for my reactor.
Looks like I will need a neutron shield.

I would think expanded polystyrene would be a good one. It works by compton
scattering from the carbon in the plastic.

I see only 1 or 2 KeV energy of collision is required and the nuclei density
is 10^19 /m^3. That is what I intend to use in my reactor.

Expanded polystyrene is no good. At least you need massive polystyrene.
I would use polyethylene or paraffin for greater hydrogen content.
What you have then is a reflector.

But ... scattering doesn't help.
What you need is a cadmium neutron absorber, probably lead will do.
It doesn't harm that the neutrons are decelerated by plastic though.

If you would manage measurable neutron flux, that would be spectacular.

Who the FUCK cares who you are? Only what you say has any meaning, if any.
