Study on the beam properties of the microwave ion source

A test bench of the microwave ion source has been developed at Korea Multipurpose Accelerator Complex (KOMAC). Several modifications were done to improve the performance of the ion source. Beam properties such as an emittance and a profile were measured according to the operating parameters and extraction geometries. In this paper, the characteristics of ion source at test bench are presented in a viewpoint of the beam properties and the improvement of the ion source for 100 MeV linac based on the result is reported.
