CX1191D Deuterium Thyratron

by 얼라이드이파트 2013. 9. 13.

ABRIDGED DATA

Deuterium-filled tetrode thyratron of ruggedised construction,suitable for use in airborne or
mobile military radar systems. It isused for switching peak powers up to 8.0 MW at high repetition
rates under a wide range of operating conditions. It has arugged, internally connected reservoir.
Samples are subjected to extensive environmental test procedures including vibration
at 2g from 50 to 200 Hz.

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
