Abstract

An 18 GHz ECR ion source (NIRS-HEC) has been developed to produce highly charged heavy ions from Ar to Xe. In order to increase the beam intensity of highly charged ion, we tried a technique of supplying cold electrons into the ECR plasma. In this paper, enhancement of the beam intensity is discussed in detail. The bias voltage is applied on the probe to repel cold electrons which flow from a plasma. The output beam current is 130 e{mu}A for Ar{sup 11+}. (J.P.N.)
