摘要: 利用红外相机对HL-2A装置外偏滤器靶板的表面温度进行了测量,得到了具有一定时空分辨的红外热图。用一维热传导模型对热点处的温升进行数据处理,得到了轰击点上的热负荷演变曲线。分别对辐射偏滤器、ECRH加热、中性束注入、破裂四种放电情况下的热负荷曲线进行了分析,并就辐射偏滤器和破裂两种放电的热负荷与靶板探针测得的结果进行了比较。

Abstract: The surface temperature of the outer divertor target plate in the HL-2A tokamak is measured by an IR camera, the thermal graphs with temporal and spatial resolutions are obtained and the evolution of the heat load at the strike point is obtained by a 1-D calculation. The heat fluxes of four kinds of discharge, i.e. radiation divertor, ECRH, NBI heating and disruption are analyzed; and the results are compared with the results measured by the target probes in radiation divertor and disruption discharges.

Key words: Heat flux, Infrared camera, One dimensional model of heat conduction, Inverse problem of heat conduction, Divertor target plate
