A versatile pocket PIG ion source with permanent magnet

A versatile pocket PIG ion source with permanent magnet is described in this paper. The source can produce both gas or metal and some negative ion beams. Normally 1-2 mA gas ion beams can be extracted at 40 W discharge power. Using Ar as auxiliary gas, tens of mu A of solid or metal ions from cathode material are produced by cathode sputtering. The negative ions of some elements with larger electron affinity can be extracted from the source directly, so far using LaB6 as cathode, more than 50 mu A of H-, 1-2 mA of O- and F- ion beams have been extracted at 15-20 kV extraction voltage, the power consumption are normally less than 40, 50 and 100 W, respectively.Instruments & InstrumentationNuclear Science & TechnologyPhysics, Atomic, Molecular & ChemicalPhysics, NuclearSCI(E)EI1ARTICLE1-2148-15011
