The temperature range is from 250℃ to 1200℃. The two dimensional temperature profiles of the first wall during both major and minor disruptions could be measured with an accuracy of about 1% of measuring temperature, which is adequate for tokamak experi- ments. This offers a very useful tool for disruption study, especially for the research of divertor physics and edge heat flux on HT-7U superconducting tokamak.展开更多
