Figure-Experimental study on heat load of plasma-facing components by the calorimetry system in the EAST tokamak

Fig.1 Distribution of the water cooling modules in the EAST, which is produced by CAD.Fig.2 Heat load distribution estimated from the calorimetry system in discharges with an upper single null divetor configuration in the EAST tokamak. Data is from the calorimetry system in EAST.Fig.3 Waveforms of the total heating power, heat load in the upper divertor and its change rate. The results are derived from the measurement by the calorimetry system in EAST.Fig.4 Time evolution of the water temperature difference for upper and lower divertor, respectively. The corresponding characteristical time can be used as a measure of the cooling capabitlity of the water cooling system.
