x-ray calibrations

On the subject of calibrating survey equipment for analytical x-ray
machines:

Unfortunately, both electron microscopes and x-ray diffraction units.  
Double-unfortunately, as we are a research university, current/voltage/target
material in the XRDs is quite varied.  Triple-unfortunately, I also have
amusing things such as accelerators, experimental fusion devices and the
like to survey around. :-)  However, for the purposes of the question of
calibration appropriateness, let's say the equipment consists of EMs and
XRDs.  The XRDs are for the most part in interlocked, shielded enclosures.
