Abstract
An enhanced ion flux is achieved with a cold cathode discharge maintained at approximately=10-4 Torr, by incorporating the charged particle oscillator arrangement. The construction and the operating conditions of this source in conjunction with a photoelectron spectrometer are described. An intense line emission is obtained from He, Ne and Ar ions and this affords a convenient windowless photon source of He II (304 and 256 AA) and Ne II (461 and 462 AA) for photoelectron spectroscopy. With Ne and Ar the many emission lines of the ions are available for photoionization experiments and the low pressure conditions of the source favour its application in ultrahigh vacuum.Keywords
