[net.physics] what is a crytron?

wa371@sdcc12.UUCP (wa371) (05/17/85)

Crytrons have been in the news lately.  It was asserted that they are 
indispensable for a nuclear bomb, and that Isreal has acquired many crytrons,
contrary to the wishes of the U.S.A., and that they are only manufactured
by Edgerton, Germeshousen, and Grier in this country.
So, someone please explain the details of a crytron.

If it is the same sort of crytron I'm thinking of, its an ultra fast
vacuum tube style high voltage switch. They put a minute amount of
radioactive gas in the thing so that the ionization time of the gas
inside the tube is shortened. Crytrons are used to turn on pockel cells
for Q-switching solid state lasers to increase the peak energy output
by cavity dumping.
