Spatial Variation of Electron Energy Distribution Functions along to Field Lines on ECRIS

Fundamental studies have been made to elucidate the basis of various physical processes and physical phenomena in electron cyclotron resonance (ECR) plasma. In order to obtain guiding principle for further improvement of the state of art technology on ECR ion sources (ECRIS), it is the object to develop moreover efficiencies of them in new fields together still existing applications in various field. In this paper, spatial variations of electron energy distribution function (EEDF) have been experimentally measured and reported with relationship extracted ion beam currents and other parameters.
