| Description |
Argon-Hydrogen filled spark gap, for use as radar modulator. Corona trigger electrode inside the cathode, to start the firing. Aluminum cathode, nickel or iron anode. By design the tube must be operated with the cathode opening downward; the aluminum eroded by sparks is mostly transferred to anode, leaving approximately constant the electrode spacing through the useful life.
- 2.7KV per gap firing voltage
- 75A peak, 75mA average
- 1100pps max.
Introduced by WE during WWII. Registered in 1948, when already discontinued. Third issue of datasheet dated 1943.
Two used in the 10.5 kW pulser of AN/APS4 to drive the magnetron 2J21.
