一、引言在聚变等离子体研究中,中性粒子束注入在加热、诊断、添料、控制稳定性诸方面都具有重要意义。一条中性束束线的规模在很大程度上取决于离子源技术的水平。198年,我所成功地研制了一台七厘米离子源,为它配套的束功率为80kW的中性束注入器实验台也于1984年底建成。但是,这样的功率水平用于HT—6M托卡马克注入加热还嫌太小。按照最初方案,必须提供净功率1MW的中性束功率,分两路注入,每台
I. INTRODUCTION In the research of fusion plasma, the injection of neutral particle beam is of great significance in heating, diagnosing, adding materials and controlling the stability. The size of a neutral beamline depends to a large extent on the level of ion source technology. In 198, I succeeded in developing a seven-centimeter ion source, and its matching beam power of 80kW neutral beam injector test bed was also completed by the end of 1984. However, such a power level is too small for HT-6M tokamak injection heating. In accordance with the original program, you must provide a net power of 1MW neutral beam power, injected in two ways, each
