What a find!
That tube is a H2 thyratron/tetrode. Here are some specs (full specs
soon at nic).
"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."
Look at nic for full specs soon,
