	Bob- that would be great for getting the injector turned on, but
how do you turn off a thyratron once it's ionized? You would also have
to have some other means of killing the current to the injector...
like an SCR, once it's on, it stays on.
	Of course, it's been 25 years since I played with tube
circuits...
