Krytron (sp) ?

Are you sure we're not talking about "Klystrons" ? In the early days of Radar, klystrons were used
as LOs in radar sets. As I understand it, the power capability of klystrons has grown to the
extent they have pretty much replaced the magnetron in modern Radar.

EG&G, among other things, was the instrumentation contractor at the Mercury, NV underground testing
facility.


Ask on news:sci.electronics.design if you don't believe me. A
Krytron is an ultra fast electronic switch that allows a very high
current to be switched. It is used as a trigger. There isn't a lot of
published data, since it was designed for a specific use.

A Klystron is used as an oscillator or amplifier.

I've worked with 65 KW Klystrons. Big, heavy and use lots of
distilled water in the cooling systems.
