What tube and power supply are you running?
Let's start with the Tel-X-Ometer?
These are self-contained X-Ray experiment stations, college level trainers and instrument. It has a 20 kVp/30 kVp switch selectable HV power supply, a hard vacuum copper target X-Ray tube (80 uA Max), built in goniometer, experiment holder, timer, X-Ray and scatter shielding and like most X-Rays it is key-operated.
Uses include XRF, XRD, Bragg Diffraction,? X-Ray Radiography and the list goes on and on. Manuals attached. Made in England, now sold by 3B Scientific, I've serviced many of these and have several in the shop right now.
