Oscillations in a duoplasmatron ion source

  • 1. National Lab. for High Energy Physics, Ibaraki-ken, Japan

Description

Coherent oscillations with the frequencies of 1 to 3 MHz were observed in a high current pulsed duoplasmatron for hydrogen gas. The dependences of the frequencies and amplitudes on the source parameters are presented. The oscillation frequency increases as B increases. It is inversely proportional to the I. E.-to-anode distance, and has an approximate dependence of 1√M for different gases. It seems reasonable to explain the oscillation in terms of ion-acoustic wave in the anode plasma. Operation at high arc current with weak magnetic field is favorable for obtaining oscillation-free beams
