摘　　要：SWIP-RFP装置是具有金属真空室的环形反场箍缩(RFP)装置.在初始气压,初始环场,可控辅助反场和等离子体自反效应的不同情况下,做了反场建立条件的实验。在有自反效应和可控辅助反场时间配合的三种运行情况下,反场箍缩放电已实现.本文给出了反场箍缩位形实验观测的结果,实验测出反场箍缩位形的等离子体电流幅值。脉冲长度与相关因素的依赖关系.实验结果表明在无功率短路情况下,等离子体存在时间τ_p≥0.3ms。The device is a toroidal RFP machine with a metal wall ( R/a = 0. 48/0. 1 ). The conditions for establishing RFP have been studied for different filling pressures,initial fields,aided reversal fieids of control and plasma self-reversal effect. The RFP discharges have been realized in three operation cases with the time matching of the self-reversal effect and toroidal field control.Experimental observations of reversed field pinch (RFP) configuration,plasma current value and its duration are given in this paper. Dependent relations of relevant factors are also shown. In the experiments, F-curve,displacement of plasma column,distributions of B(?)and B0,electromagnetic measurement results,photo electricity signals and plasma existing period are all consistent with each other. The experiment results indicate that the piusma exists for over 0. 3ms with a passive crowbar in the SWIP-RFP device.
