Plasma and Ion Beam Characteristics of the Dynamag Ion Source

Abstract

A description of an ion source of the duoplasmatron type is given. Experimental results related to the plasma density distribution in the region between the intermediate electrode and the anode are given and discussed. Ion beam behavior in the extractor region as a function of extraction potential and total current has been studied. Also, ion beam space‐charge neutralization by secondary electrons has been looked for, but not observed under present conditions.
