14GHz强流质子源的研制与调试

Development and Commissioning of 14 GHz Intensity Proton Source

提出并初步研制成功一台利用14GHz微波产生强流质子束的离子源。2013年在搭建的实验平台上进行了初步调试。在40kV引出电压、200 W及14GHz条件下,引出直流质子混合束流4mA,初步调试结果证明其工作机制和设计结构可行。本文对该质子源及其实验平台进行详细说明,并对实验结果进行讨论。

A high intensity ECR proton source with 14 GHz microwave heating was pro- posed 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 2 H＋ and 3 H＋ are included. The suc- cessful 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.
