Abstract

The successful conversion of the JET, (Joint European Torus) neutral injectors to operate in helium has further enhanced the usefulness of neutral injection on JET. Each of the two injectors can now operate in H, D, /sup 3/He, or /sup 4/He. The operation of a long-pulse /sup 3/He NBI (neutral-beam injector) has been demonstrated for the first time. Up to 7 MW of /sup 4/He and 13 MW of /sup 3/He neutral beam power have been injected into JET. The beams have been operated at energies up to 150 keV, with pulse lengths up to 7 s.<>

有氦中性束系统的经验
JET (Joint European Torus)中性喷射器在氦气环境下的成功改造,进一步增强了JET中性喷射器的实用性。现在,两个注水井中的每一个都可以在H、D、/sup 3/He或/sup 4/He井中工作。首次演示了长脉冲/sup 3/He中性束注入器(NBI)的操作。高达7兆瓦的/sup 4/He和13兆瓦的/sup 3/He中性束功率已注入JET。这些光束的运行能量高达150 keV,脉冲长度可达7秒。
