Ion Source Development for the los Alamos Heavy Ion Fusion Injector

A multi-beam injector is being designed and built at Los Alamos for the U.S. Heavy Ion Fusion Program [1]. As part of this program, development of an aluminum-spark, pulsed plasma source is being carried out. Faraday cup diagnostics are used to study current emission and to map the current profile. An aluminum oxide scintillator with photographic film is used in conjunction with a pepper-pot to obtain time integrated emittance values.
