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.
