I remember reading the original article and was sore tempted to build 
the rig, but was a little scared about the X-rays.  Not too long 
before that time, it was still possible to pick up a junked shoe 
fluoroscope to do the same thing a little better.

I've long wondered about using a HV rectifier tube as a source of 
soft X-rays, though.
