Prototype Rentgen

It is a prototype of a miniature rentgen tube, allowing to change the katode - anode distance from .5 to 3 mm with .05 mm precision and to be pumped down to 1E-8 mbar and with changeable katode and anode. The idea is carbon nanotubes to be used as a cold kathode (reaching heat power of 2-5W for maximum up to 50kEV rays ... intensity is still unknown)
