The CV1141 thyratron dates from 1950 and is an elegant looking valve. The finned structure is the gate or grid, used to trigger the main discharge between the cathode and anode.

The maximum operating frequency was 10,000 pulses per second. The drop across the valve was 15 - 18 Volts and the control ratio was 40.

The classic envelope is 46 mm in diameter and, excluding the B5 base pins, is 112 mm tall.
