CX1551 Thyratron

 

ABRIDGED DATA
Deuterium-filled tetrode thyratron, featuring low jitter and low anode delay time drift. Suitable for use at high pulse repetition rates, in parallel for switching higher powers, or for switching long pulses. A reservoir operating from the cathode heater supply is incorporated. The tube is flange mounted with flexible lead connections.
