Subject: Power Supply for Crookes/Geissler Tubes

I have a small NST, 7500V at 20mA.  If I controlled it with a variac, and put a HV diode on the output as a half wave rectifier,would it make a suitable power supply for a Crookes tube?  I'm not sure how the tubes respond to power, would I need to so something additional to limit the current?

Thanks,

Curt.
