Development of a thermal probe method for heat flux and ion temperature measurement in the divertor simulator MAP-II

Abstract

The thermal probe method is capable of measuring ion temperature using the heat flow from plasma (Q(plasma)) versus the bias voltage (V-p) characteristic. Considering the heat transition phenomenon in the probe, we designed the thermal probe in order to obtain the Q(plasma)-V-p as well as the I-p-V-p characteristics. We performed a preliminary experiment of the thermal probe measurement in the divertor simulator MAP-II, and discuss the results and the assignments of the thermal probe method.
