The fundamental studies for generating flash vacuum-ultraviolet (VUV) rays using a surface- discharge glass substrate are described. The experimental setup consisted of the following components: a negative high-voltage power supply, a high-voltage pulser with a condenser capacity of 14.3 nF, an oil diffusion pump, and a glass vacuum chamber for generating VUV rays. The VUV chamber employed a surface-discharge glass substrate and was connected to an oil diffusion pump which allowed operation at a pressure of 1 X 10(superscript -3) Pa. The high-voltage pulser employed a polarity-inversion-type transmission line having a gap switch. Since the combined ceramic condenser was charged from -20 to -30 kV by a power supply, the maximum output voltages from the pulser were about -1 times the charged voltages. The VUV rays were produced after closing a gap switch. The maximum values of the discharge voltage and the current were about 17 kV and 1.8 kA, respectively. The radiation outputs with various photon energies were measured by a combination of a plastic scintillator and a photomultiplier. The pulse durations of the VUV rays were nearly equivalent to the durations of both the discharge voltage and current which displayed damped oscillations, and the widths were about 10 microsecond(s) .
