NLCX1140 Hydrogen Thyratron (tetrode)

The CX1140 is Hydrogen Thyratron capable of blocking 25Kv peak and
pulsed anode currents of 1000A
I have no pin out data but I have the specs below

configuration - Tetrode
peak anode current - 1000A
average anode current - 1.25A
peak forward voltage - 25kV
peak output power - 12.5 MW
heating factor - 9x10^9
heater voltage - 6.3V
heater current - 22A


"Suitable for use at high pulse repetition rates, in parallel for
 higher powers, or for switching longer pulses. Hydrogen reservoir
 operating from the cathode heater supply is incorporated."

Peak forward anode V = 25kV max
Peak anode current = 1000A max
Average anode current = 1.25A max
Rate of rise of anode current = 5kA/us max

Cathode connected to mid-point of heater
Heater V = 6.3V
Heater I = 21.5A
Cathode heating time = 5 minutes

NOTE: "X-rays are emitted by cx1140 from the region of the anode , but
the radiation is usually reduced to a safe level by the metal panels
of the equipment in which the tube operates."
