EG&G KN6 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 KN6 was used to trigger an arc lamp in the Gemini and Helios YAG laser fusion program at Los Alamos Scientific Laboratory (LASL) at the time, Los Alamos National Laboratory (LANL) today. It was also used in the Hewlett-Packard 43115 trigger amplifier.
