A high-current hollow cathode as a source of intense line radiation in the VUV

Abstract

Abstract. The vuv line emission of a high-current DC hollow cathode was investigated in the wavelength region 10 nm to 100 nm. Spectra of quadruply ionised atoms could be observed.The radiance in the AI IV lines at 13 nm and 16 nm and in the He I1 Lyman-series was determined by a comparison with the spectral concentration of radiant intensity of the synchrotron radiation emitted by the electron storage ring BESSY. We found the radiance of the lines to be reproducible within 5 2 5 % .
