A Study of Reversed Field Pinch Experiments Using a New Programming Mode

摘要

A mode of external field programming for setting up a reversed field pinch (RFP) is tested. An initial plasma with a screw pinch followed by external field reversal is created. The program is described and the equilibrium relation with respect to the minor radius throughout the setting up phase is examined. A one dimensional stability analysis based on an ideal MHD model is applied to the experimental results. The instability which is m = 1 resistive tearing mode under the influence of viscosity, is discussed. High current operation at 110 kA using the new programming is evaluated.
