We describe a valve used to separate a plasma operated at pressures higher than 5 mbar from a heavy ion beam line. The very fast opening of the valve prevents the ion beam from being perturbed by the neutral gas before entering or after exiting the p

In this paper, a large spectroscopic study of a hollow cathode discharge produced in a concentric cylinder perforated tube is presented. First, the NCd cadmium ground state and the He(23S) metastable concentrations are determined from laser absorptio
