Negative ion currents (HÀ, DÀ, TÀ) of 50–150 mA are possible to be extracted from the source. 5 Ion Sources for Electrostatic Accelerators The purpose of ion sources in high energy accelerators  is to produce either positive or negative ions from neutral atoms. Positive ion sources are placed inside the tank of a single-stage accelerator (Van de Graaff accelerator); negative ion sources inject the ion beam into the tank of a two-stage accelerator (Tandem accelerator). In single-stage accelerators (Van de Graaff accelerator), mostly RFand Duoplasmatron ion sources giving positively charged ions are used.
2 Ion Sources 41 Fig. 1 Hot Filament (Hot Cathode) Ion Sources The Bernas ion source  consists of a discharge chamber with an isolated thermionic filament (or cathode) providing a source of primary electrons which cause ionization of the atoms introduced into the arc chamber by gas feed or by vapor feed from a heated oven (Fig. 7). As shown in Fig. 7 the primary electrons revolve around the magnetic field lines towards to the so-called repeller (anticathode) negatively biased relative to the arc chamber.
