Ring Magnetron Ionizer

摘要

A ring magnetron D sup - charge exchange ionizer has been built and tested. An H sup - current of 500 mu A was extracted with an estimated H exp 0 density in the ionizer of 10 exp 12 cm exp -3 . This exceeds the performance of ionizers presently in use on polarized H sup - sources. The ionizer will soon be tested with a polarized atomic beam. (ERA citation 11:017070)
