NOTES

1. The maximum permissible peak forward voltage for instantaneous starting is 20 kV and there must be no overshoot. For single-shot and crowbar applications, each tube is tested to withstand 35 kV DC at 6.3 V heater voltage for 10 minutes, with 100 mA grid 1 drive current and 7100 V grid 2 bias.

2. Clamping is only permissible by the base.

3. In some applications, air cooling may be necessary to prevent the base temperature from exceeding 200

NOTES

1. The reservoir heater must be decoupled with a suitable capacitor to avoid damage by spike voltages.  The recommended reservoir heater voltage for each individual tube is stamped on the tube envelope. This recommended value is determined for hold-off at the maximum anode voltage under DC conditions.
For lower voltages and modulator operation the reservoir heater voltage should be increased to a
value consistent with voltage hold-off at the operating level. Maximum reservoir voltage (i.e. maximum gas pressure in the tube) is one prerequisite for maximum thyratron life. The reservoir voltage should be stabilised to +0.05 V.

 

2. The tube must be fitted using its mounting flange.
