Abstract

A filament ion source was investigated for the optimum parameters required for ion production. The argon filament discharge was operated at pressures 3.0–9.0x10^–2 Torr with a discharge voltage of –50V. The discharge current was measured as the filament current was varied from 9–12.3A. A multicusp magnetic configuration increased the discharge current by ~4mA. Extremely low discharge resistance was observed at higher filament currents signifying a highly conductive state. Filament current of 10.5A with a multicusp confinement and gas pressure of 9.0x10^–2 Torr were the optimum parameters determined to produce a sufficient level of discharge current suitable for extraction.
