Jake,
Believe what you will. The fusion reaction curves (Cross-section
data) are shown in
books like Accelerator Health Physics by Patterson and Thomas, Nuclear
Physics by Kaplan and/or
Segre etc
Good luck with your Fusor work --- I have nothing against it. I just
don't want some high school
kid having a serious accident.
If you Fusor guys think you are scooping someone, discovery-wise,
don't be deluded.
It's already been done by serious physicists using serious equipment via
Migma or some process
like it. My guess is still that Team USA has a working Submarine or
Aircraft Carrier powered,.
at least some of the time, by Migma. The discoveries give team USA a
tactical advantage over other
Nations, so you won't hear about it for another 25 years.
In 1975-1976, Maglich and his colleagues had a Migma vacuum chamber, a
Superconducting
Magnet to produce the necessary magnetic field and they also had a 2-3 MeV
Van de Graaff
accelerator supplying beams of deuterium, tritium, etc. Since then
they've had time to do more
work on Migma. Then the project went very silent. Now Maglich and
Company are doing work
again at Calsec. The other companies were Fusion Energy Corporation and
Aneutronics.
Maybe you are right about a simple fission/deuterium device NOT
working. Usually, the silence in
such matters by US DOE/DOD people is deafening. You won't hear a Peep.
Again good luck with your Fusors.

Dr. Presig, as a "fusioneer", I may have some answers to your
concerns. Though the equipment used in fusors is often nonstandard (my
powersupply is two NSTs hooked to a voltage multiplier made of microwave
oven capacitors), it poses negligible risk to anyone other than the
operator. Yes, the potential for a nasty accident is omnipresent, but it
would not result in damage on a large scale. The same goes for neutron
shielding. The best amateur fusor yet made produced a paltry 5 million
neuts/sec, which poses a negligible risk to anyone standing more than a few
meters away. X-rays are of a far greater concern. In addition, deuterium
does not pose a proliferation hazard in any way. While massive amounts of
heavy water were a concern in WWII (because of its use as a moderator in a
reactor that could produce plutonium), it is of little concern in this day
and age. It is not fissile or radioactive and cannot be easily used to
boost a nuclear device. Simply packing a small nuke in a deuterium blanket
would do nothing, as the ignition of D-D fusion is considerably harder than
the D-T process used in thermonuclear weapons (if you would like proof, I
have the cross section data). Even the largest hydrogen bombs (using "easy"
D-T fusion) rely on carefully designed hulls to reflect gamma rays to heat
the fusion fuel, which only then can go off. Needless to say, no scheme of
deuterium surrounding a stolen Russian nuke could ever pull this off.
