Source of multicharged ions of solids for accelerator

An effective multicharged ion source with the cathode sputtering of working substance based on the cyclotron ion source with the indirectly heated cathode and electron oscillation is described. Multicharged ions of more than 30 elements are produced from this source: high-charged ions of metals from Li to Th, of semiconductors and of some metalloids (B, C, P, S, Se). Intensity of the multicharged ion beams lies in the range from tens of μA to several tens of mA. The ion source have been used for heavy ion cyclotrons of the Laboratory of Nuclear Reactions of JINR for many years. Ion sources in other different equapment are based on this ion source. Manufacturing techniques for sputtering electrods from different materials are described
