摘要

测试NBI大功率强流离子源的综合测试台正在建设

已研制了离子源等离子体发生器电源系统、等离子体电极高压电源及梯度极分压器、抑制极负高压电源等电源系统

以及高压传输线及缓冲器

在测试台上开展了对EAST中性束注入器第一台兆瓦级强流离子源样机进行整体电源系统测试和离子源起弧放电的初步测试

完成了离子源电源系统初步性能测试及系统整体联调

给出了各套电源系统测试运行达到的参数指标

在兆瓦级强流离子源样机上获得了首次离子源起弧放电的实验结果。

Abstract

For the neutral beam injector(NBI) of the Experimental Advanced Superconducting Tokamak(EAST)

a test stand of a high-current ion source has been in construction.The NBI power supply system includes the plasma generator power supply

plasma electrode power supply

high voltage power divider

negative high voltage power supply

and the transmission lines and the snubber.A multi-megawatt prototype ion source was developed.The arc discharge of the prototype ion source was obtained in the test.The test results for the ion source power supplies and the arc discharge of the ion source are presented.
