Title: Radiation Efficiency of AC-excited Micro Hollow Cathode Discharges

Abstract

This contribution reports on micro hollow cathode discharges (MHCD) generated in a device supplied by rectified but non-filtered low-frequency currents to preserve the cathode function of one micro electrode. The vacuum ultraviolet (VUV) radiation efficiency of such an MHCD was investigated in high-pressure argon in the frequency range from 40 kHz to 140 kHz. Both the currents and voltages of the MHCD device are nonlinear and the power input shows a flat maximum at about 50 kHz. The VUV relative efficiency also displays a more pronounced maximum at this frequency but remains still comparable with those of the dc supplied MHCD. Unfortunately, this VUV efficiency rather refers to the resonant lines of oxygen impurity at about 130.5 nm and not to the argon excimer radiation.
