Abstract
This paper describes the study of double and multi-pulsed operations of two inductive plasma sources (IPS) for the generation of intense ion/plasma flows. Due to its simplicity and high efficiency, as compared to conventional coaxial JÃB plasma sources, the IPS looks promising for a variety of applications that require a multi-pulse mode of operation, such as: intense plasma and ion beams [15th International Conference on High-Power Particle Beams, St. Petersburg, Russia, July 2004]; high current pulsed Hall accelerators [Plasma Phys. Rep. 29 (2003) 261]; spacecraft propulsion [AIP Conf. Proc. 608 (2002) 627] and the formation of field-reversed configurations by colliding current carrying plasma tori in magnetic fusion devices [Nucl. Fusion 39 (1999) 2001]. Design, projected parameters and initial test results for several modifications of the IPS, including characteristics of the generated plasma flows, are given. The density and temperature ranged between 1012 and 1015Â cmâ3 and 2 and 10Â eV, respectively. Plasma transport velocities were measured between (1-5)Ã106Â cm/s. The multi-pulse mode produced a train of pulses with frequencies up to 10Â kHz for several milliseconds at power levels of (1-2)Ã107Â W and several joules of deposited energy per pulse. The potential and limitations of double and multi-pulse modes of the IPS are also discussed.
