| Abstract: | A prototype EAST neutral beam injection (NBI) test stand has been developed to test a multi-megawatt EAST ion source at the designed beam power. The power supplies system of the NBI test stand include a filament power supply, an arc power supply, an acceleration power supply，a deceleration power supply, a bending magnet power supply, and a snubber bias power supply. The paper explained the design structure、technical features and operation control mode of each ion source power supply. The difficulties which required to be solved for stable and reliable operation of ion source power supply were analyzed. The necessary tests of the prototype EAST NBI system have been done with high power, long pulse beams. |
