摘要: HL-2M 装置辐射量热计系统采用 16 通道光电二极管阵列作为探测器,11 个探测器阵列,共有 176
个探测通道,被设计在同一个小截面内,交叉覆盖上下偏滤器、等离子体边缘和等离子体芯部区域。数值模拟结
果显示,根据这种视线布局能够精确地估算出等离子体的总辐射功率;运用相关层析反演方法能够重建出等离子
体辐射功率密度的分布特征。在 HL-2M 初始等离子体放电中,根据中平面的探测器阵列对等离子体辐射特征进
行了初步的实验分析。

Abstract: HL-2M bolometer system was designed and optimized with the absolute extreme ultraviolet 
(AXUV) diode arrays, and 16-channel AXUV linear arrays was used as the diagnostic detectors. In order to meet 
the physical requirements, 176 lines of sight were designed within one poloidal section of the torus, and the 
geometrical arrangement of the arrays was optimized by coverage mapping and tomographic reconstruction test. 
Phantom simulation showed that the tomography methods can make reasonable reconstructions of the plasma 
emission profiles from the measurement of about 176 lines of sight. In the HL-2M first plasma operation, one 
AXUV array was installed on the midplane and got reasonable results. 

Key words: HL-2M tokamak, Bolometer, Plasma radiated power, Tomography
