Regarding as an experimental and test device , the experimental platform of ECR ion source may expediently regulate every pa- rameter of ion source , and achieve good character of beam current. Through improving on the components , ECR ion source can is modulated in 已est state. Above results may be used in the running and debugging of neutron generator. Therefore ,the experimental platform of ECR ion source is the necessary equip- ment of large beam current neutron generato r. Comparing the experimental platform of ECR ion source with domestic ones and the overseas ones , it mainly be used in the simulation experiments about neutron generato r. It is compact and experinlental platform mode in structure. It can focus the beam current and measure many parameters on line in function.
