ION SOURCE
Patent
·
OSTI ID:4134810
An improved ion source is described which provides intense ion beams with minimum molecule egress from the source; it comprises an ionization chamber in which an annular anode is positioned between a filament and an electrode, the latter of a relatively small surface area. Electron oscillation or refluxing is employed to provide elongated electron paths for increased ionization. An arc plasma is produced by electron discharge in a gaseous atmosphere to provide a large ion reservoir. Since ion and electron bombardment produces heat, the anode is cooled by fins. (D.L.C.)
