摘　　要：为了获取HL-2A等离子体的离子温度、旋转速度及其分布等重要参数,首次在HL-2A装置上开展了CXRS诊断。通过利用能有效探测微弱光的EMCCD和特殊设计的光学采集系统,获得了具有足够信噪比的诊断信号。实验得到的测量信号分析表明,设计是切实可行的。In order to obtain the important plasma parameters such as ion temperatures,rotate velocity and their profiles,a CXRS（charge exchange recombination spectroscopy） diagnosis was developed in HL-2A tokamak.In order to get the diagnostics signals with enough signal-to-noise ratio,the EMCCD detector suitable for the weak signal and the dedicated optical collection system converging light flux effectively were utilized.The experiment result proved that the design was feasible.
