Abstract

The vacuum ultraviolet emission was investigated end-on from the anode and cathode sides of a relatively thick microhollow cathode discharge. For this geometry and high xenon pressures the integral intensity measured from the anode side becomes comparable with that from the cathode side. Also, the excimer spectra corresponding to the two electrode sides are not so different as in the case of standard thin microhollow cathodes or with plane geometry. The homogeneous negative glow plasmas, which are now retained into the thick microhollow cathode, can explain this behavior..
