摘要：

An infrared imaging system has been installed on the National Spherical Torus Experiment at Princeton Plasma Physics Laboratory to measure the surface temperatures on the lower divertor and center stack. The imaging system is based on an Indigo Alpha 160x128 microbolometer camera with 12 bits/pixel operating in the 7-13 mum range with a 30 Hz frame rate and a dynamic temperature range of 0-700 degreesC. From these data and knowledge of graphite thermal properties, the heat flux is derived with a classic one-dimensional conduction model. Preliminary results of heat flux scaling are reported.
