合肥光源的工作点测量系统

摘要

The tune measurement system for Hefei Light Source (HLS) was described. The system composed of a stripline beam position monitor， a 1800 hybrid， a mixer， a spectrum analyzer with track generator， a power amplifier， and an excitation electrode. The swept frequency excitation method was used to measure the tune. Its accuracy was about 4×10-4. The chromaticity of HLS was measured using this system. The measuring results of the tune and chromaticity were given.%合肥 800MeV电子储存环的工作点测量系统采用扫频激励法进行工作点测量,它由条带束流位置检测器、1800的魔T、混频器、带扫频信号输出的频谱分析仪、功率放大器和束流激励电极等构成。该系统的测量精度约为1×104。利用该系统进行了机器的校正色品测量，给出了工作点和色品的测量结果。
