EG&G KN22 Krytron
EG&G = Edgerton, Germeshausen, and Grier, Inc., now URS Federal Services (USA).
A krytron is a high speed, high current gas filled tube, somewhat similar to a cold-cathode thyratron. It consists of a sealed glass tube with four electrodes. The fourth terminal is a “keep alive” electrode that maintains a glow discharge in the tube at all times. A small triggering pulse on the grid electrode switches the tube on, allowing a large current to flow between the cathode and anode electrodes. There is also a small amount of radioactive 63Ni (<4 μCi) in the tube, which helps further stabilize the propagation delay.
The KN22 was used as picosecong triggering for laser switching.
