Design and operation of a high pulse rate intense ion beam diode
- Laboratory of Plasma Studies, Cornell University, Ithaca, New York 14853 (United States)
Virtually all practical applications for intense ion beams require that the beam pulses be generated at high repetition rates. This paper reports the development of the first high pulse rate, long-lived ion beam diode. It is a magnetically insulated diode which has produced {similar_to}75 keV proton and carbon beam pulses of 1.0--2.5 A/cm{sup 2} and 100 ns duration at up to 90 Hz in four pulse bursts. It has also produced 125 keV, 5 A/cm{sup 2} Ar beams at a steady 1 pulse per 30 s for over 1000 pulses between failures in many runs. This diode employs a magnetically confined anode plasma ion source, and the high repetition rate pulsed power systems are based upon saturable magnetic switching.
