摘　　要：为了实现等离子体温度和环向旋转速度的测量,在HL-3装置上发展了一套环向电荷交换复合光谱诊断(CXRS)系统,该诊断系统通过测量电荷交换谱线的多普勒展宽和多普勒频移得到离子温度和旋转速度。HL-3装置上的CXRS系统测量CVI(n=87,529.05nm)谱线,共有32个空间通道,覆盖等离子体的整个弱场侧半径R为1.70~2.43m、空间分辨率为1.0~2.5cm、时间分辨率为5~50ms可调,由光谱强度决定。目前已经实现了离子温度和旋转速度的测量。A toroidal charge exchange recombination spectroscopy(CXRS)diagnostic system on the HL-3 tokamak is developed to measure ion temperature and rotation velocity,which are derived from the Doppler broadening and Doppler shift of the charge exchange spectral lines.The CXRS system measures the CVI(n=87,529.05nm)spectrum line,and it has 32 channels covering the low field side of the plasma from R=1.70m to R=2.43m with spatial resolution to be 1.5~2.5cm.The time resolution of the system is expected to be 5~50ms,which is determined by the spectrum intensity.Now ion temperature and rotation velocity have been obtained during the experiment.
