The present work describes the principle, structure and experimental results of a side extraction PIG ion source with permanent magnetic mirror type field. The source is light and handy with low power consumption and high ionization efficiency. In the experiments using BF3, N2 and Ar, total beam current of 1-2 ma can be obtained with 50-150 watt arc power. The relative yields of 11B+, 14N+, 40Ar2+,...
