Abstrakt: A Penning discharge was investigated photoelectrically as a light source from 100 Å to 300 Å. The source showed reasonable stability—10% over an hour’s operation. Bright spectral lines observed were a mixture of lines from the filling gas (Ne) and from sputtered cathode material (Al). The discharge was found to be an intense line source; an estimate of the brightness of the 160 Å Al iv lines shows them to be comparable with the highly ionized metal lines appearing in a pulsed tokamak discharge. Satellites of the Al iv resonance lines at 160 Å appear clearly in the spectra.
