On the possibility of current increase in negative ion sources with ion bombardment

Description

Optimum conditions of Cr- negative ion yield in the process of chromium surface bombardment with Ar+ ions are studied. It is shown that Cr- ions are formed as a result of sputtering and fragmentation of chromium atom complexes with oxygen. There exists optimum ratio between Ar+ ion current density and oxygen pressure in the target chamber under which Cr- ion yield is the maximum one
