The fusors do indeed produce D-fusion neutrons, measured directly
with He3-, B10-, BF3-tubes, doped scintillators, bubble dosimeters etc..
As well, the neutrons have been used for activation, and the energy
spectrum measured from activated metals using MCA with NaI(Tl) to
detect the characteristic peaks.

Of course, the fusors produce lots of x-rays and gamma too.

The "flash" is actually a beatiful "star" in the middle
of the vacuum chamber with the electrostatic confinement
electrodes, and it stays there - ie. not any flash but
a plasma lasting as long there is the high-voltage.

An enthusiastic amateur can do wonderful things. :)
