Welllll. I am not an expert on this, but distinctly
recall that some X Ray tubes, anyway, are (were?) used in
'self rectifying' mode:
The XRays would only be generated half the time,
pulsed at the supply frequency.

Just fine with 50/60Hz supply. Less so for 'Teslaish' freqs.
(Tho I've never heard of a 1 mS limit: may be my ignorance.)

I don't think the purpose was stated...
A full on Tesla Coil is rather more voltage than may be needed,
depending on intended XRay use.
(Pointless gossip:
used to be (still is?) Some ue of vdG generators to run
XRay tubes. Happens i worked, briefly, on airport XRay
systems: all the HV stuff was 'prepackaged', we did not
get past running some voltage cals...)
