摘　　要：HT-7中性束诊断电源系统的计算机控制系统由PLC、工控机、逻辑控制和定时单元等组成。对起弧、束流引出等实验进行了研究。在多种参数下,通过调节弧压、进气量等观察了其对弧流的影响。初步实验结果表明,在高压35kV、弧流80A的情况下,束电流可以达到3.6A,引出的中性束流功率可以稳定地达到50kW以上。Control system of power supply for HT-7 diagnostic neutral beam source was composed of PLC, timer and master control logic. The experimental results show the good facility and reliability. The arcing and beam extraction are studied experimentally. The influences on the beam current are observed by adjusting arc voltage and gas injection at different cases. The neutral beam power of 50kW and beam current about 3.6A were obtained in this operation priod with 35kV HV and 80A arc current.
