Abstract :
A 1 J-70 kV Marx generator triggers a discharge in a hollow cathode-pointed anode geometry. The X-ray emission is recorded by an intensified camera having 5 ns opening time. Small spots are observed either on the anode or on the insulator and their vicinity. The intensity is measured by means of a calibrated PIN diode. The spectral composition is determined using metallic foils as absorbers. The emission intensity and its duration varies with the pressure. The maximum intensity is obtained at 0.1 mbar for a 5 ns pulse
