摘要
利用对PV 10型压电阀定标实验 ,研究了中性束注入器Tank内补充气体的参数对离子源放电弧电流的影响 ,对比压电阀脉冲电源的脉宽和幅值 ,显示后者对Tank内补充气体量具有更显著的线性关系。据此进行的中性束注入器离子源放电实验结果表明 ,采用压电阀定标值计算获得的参数 ,可以稳定重复地获得最大放电脉宽达到 4 0 0ms的等离子体弧电流 ,为下一步向托卡马克装置注入高能中性粒子束奠定了应用基础。
Influence of the gas supply into the neutralizer tank of the neutral-beam-injection(NBI) ion source on discharge-arc current was studied with a piezoelectric valve,Model PV10,in the calibration experiment.The results show that the supplied gas quantity depends linearly on the amplitude of the controlling power supply.In the calibration,a few physical quantities of technological interest were calculated also.We can achieve a stable and repeatable discharging plasma-arc current with the maximum pulse width of up to 400 ms,which may significantly improve the injection of high-energy neutral beam into the Tokamak.
