Observation of enhanced negative hydrogen ion production in weakly magnetized RF plasma

摘要

Negative hydrogen ion concentration is measured during the afterglow of an axially magnetized, pulsed RF plasma source utilizing photodetachment technique. Observed negative hydrogen ion density peaks sharply around B-0 = 10 similar to 20 G and is about four times larger than that of non-magnetized plasmas. This enhancement strongly correlates to corresponding peaking in electron density. (C) 2003 Elsevier B.V. All rights reserved. [References: 17]
