摘要
介绍了合肥光源储存环紫外光束团截面及束流发射度测量系统．本系统采用光学探测,由光学成像和图像采集处理两大部分组成．光学成像部分利用光学成像将中心波长366．1nm紫外光1:1成像于CCD探测器上．图像采集处理部分将CCD探测器采集的视频信号由电缆输出到图像采集卡进行图像采集,然后由LabVIEW程序进行数据处理获得束团截面尺寸以及束流发射度和耦合度,最后给出了实验结果．
The paper describes the ultraviolet light beam profile and emittance measurement system for HLS （Hefei Light Source）. The system is based on the optical measurement, composed by two functional blocks： optical imaging and image acquisition. The optical imaging system is to form the 1：1 image of the ultraviolet part of SR on the surface of the CCD. The image acquisition system receives NTSC signal from the CCD camera which acquires the image of the ultraviolet part of SR, the signal is processed by a LabVIEW program to obtain the beam information of beam profile size, emittance and coupling between vertical and horizontal directions. Some measured results are also given.
