Experimental results of reversed field pinch on SWIP-RFP device

摘要

Experimental observations and their results of reversed field pinch (RFP) on SWIP-RFP device with a determined discharge program and under different gas pressures p(sub 0) (H(sub 2)), different charge voltages of poloidal magnetic field bank 2 (), toroidal magnetic field bank 1 (), and toroidal magnetic bank 2 () are reported. Relationships between relevant factors and plasma current (I(sub p)), plasma current duration ((tau)(sub p)) are also given. From the experiments, F-(Theta) curve, displacement of plasma column, distributions of B(sub (theta)) and B(sub (phi)), electromagnetic measurement signals, photo-electricity signals and (tau)(sub p) are determined and they are consistent with each other. The results show that (tau)(sub p) > 0.3 ms without power crowbar on SWIP-RFP device. (Atomindex citation 27:003840)
