	Most are NOT vacuum at all, being backfilled with
	Argon, or whatever, to help keep the filament from
	evaporating itself onto the inside.

	There is little higher than xrays (ok: hard gammas:

	also hard to make.

	Almost always need hard vacuum for xray production.

	Might do some test runs with film, in light tight
	packet.  Hard to know how to calibrate results.

	(Tesla did some experiments with xray tubes...)
