CV2224 high-speed primed trigger tube
 |
The tube measures 51x17mm overall and has a B7G base. |
This is an "exceptionally high-speed" trigger tube which finds use in all sorts of applications. This trigger tube incorporates a priming gap and a second control electrode, the shield. The positively biased shield helps to achieve very short deionisation times (typically 30µs) and, in certain circumstances, may be used as an auxilliary triggering electrode to increase the gating facilities of a single tube.
