Description
A a very compact 2.45 GHz ECR ion source is proposed and designed. An RF rotator is used, for the first time in the field of ion sources, to couple microwave power into the plasma chamber. The RF rotator is integrated with choke structures, so no separate high-voltage isolation waveguide is needed. Since the RF rotator itself naturally guides the reflected power, the circulator is also unnecessary. By removing both the isolation waveguide and the circulator, the microwave transmission line becomes very short and the source is highly compact. Moreover, the RF rotator excites a rotating wave in the plasma chamber, which may make the microwave heating more efficient.
