Abstract:

An experimental investigation has been made to determine some of the effects of a confining magnetic field on a gaseous plasma within a duplexing device. Both the parallel and crossed E and H field configurations were examined using a helium and a helium-neon Penning mixture gas fill. Temperature measurements indicate that magnetic confinement can lower the rf window temperature of a gaseous discharge duplexing device by more than 50 at pressures below 0.5 torr. Leakage power can also be reduced by 50 or more in this pressure range, but the leakage level in the parallel field device is inherently too high for practical application. Reductions of up to 4.5 to 1 were obtained in the recovery time of helium in the 2 to 50 torr pressure range using a crossedfield configuration. By magnetically confining the plasma discharge of a gaseous duplexer, the performance can be significantly improved by lowering temperatures and gas clean-up rates. Author
