摘要: The physical phenomena important in volume and surface production negative hydrogen ion sources are reviewed. phenomenon, designated production, was attributed to dissociative electron attachment of low energy electrons rovibrationally excited molecules. experimental verification 2005 the reality this mechanism is reported. Recent results obtained by measuring temperature a filament discharge source indicate that two populations present. Understanding physics operating accelerators with H− density 100 mA cm−2 range opens prospect creating caesium-free for fusion. evolution also described.A measurement effected near plasma electrode (PE) using two-laser beam photodetachment showed presence directed flow. ratio currents extracted through transverse magnetic filter field PE can be predicted from collisional flow model. A specific species plasmas transport weak described.
