| 摘 要： | 为HL-2A装置设计了一种二维硬X射线成像CCD系统，用它能直接测量硬X射线辐射强度的二维时空分布I(z，y，t)，并能得到电子速率分布fe(v，r，t)。为获得二级加热和无感电流驱动如ECH／ECCD，LHH／LHCD，ICRH／ICCD,NBIH／NBICD的效果、波可近性、共振层位置、能量沉积范围等方面的实验研究提供重要诊断手段；也可用于内破裂、大破裂、MHD，特别是q=2附近高模的MHD行为、热电子和超热电子的输运、被捕获的高能粒子图像以及与模式波(如m=1，n=1)共振引起的鱼骨模不稳定性、辅助加料引起和诱发逃逸电子雪崩现象的实验观察与研究。

| Abstract: | An advanced 2D X-ray imaging CCD system has been designed for the HL-2A tokmak. The 2D time-space distribution of hard X-ray radiation intensity, I(x,y,t), can be obtained directly with this system, and the electron velocity distribution, f_e (v,r,t), also can be obtained. The system can be a very important method for experimental diagnoses in studying the efficiency of dual auxiliary heating and non-induced current driving, such as ECH/ECCD,LHH/LHCD,ICRH/ICCD,NBIH/NBICD. It can also be used in studying the position of energy deposition, transport of energetic electrons, internal transport barrier, etc. |
