Study of Cu-KEmission from Compact Diodes Powered by Capacitor Discharge

A study of X-ray emission from compact diodes, consisting of a sharp edged cathode and a flat anode of copper energized by a 0.5 µF capacitor charged up to 30 kV and a 2 µF capacitor charged at 20 kV, is reported. The X-ray yield was measured as a function of the interelectrode spacing by using PIN-diode detectors. With a sewing machine needle
