Development and Commissioning of 14 GHz Intensity Proton Source

A high intensity ECR proton source with 14 GHz microwave heating was proposed and successfully developed at IMP. In 2013, the experimental platform was set up and the preliminary commissioning was performed. The experimental results indicate that the source can produce a total of 4 mA CW hydrogen beams with microwave power of 200 W and extraction voltage of 40 kV, in which ²H⁺ and ³H⁺ are included. The successful commissioning of the proton source demonstrates that the proposed mechanism and the structure are feasible. In this paper, the proton source and its experimental platform were descripted in detail, and the experimental results were discussed.
