摘　　要：一、引言目前,我们正在研制一台为中能电子散射用的广量程磁谱仪。谱仪包括谱仪磁铁及其供电、供水系统、多丝漂移室、多丝正比室、闪烁计数器、铅玻璃簇射计数器和相应的电子学及数据获取系统。由多次散射和探测器位置分辩限制的谱仪动量分辨约为0.16%(FWHM),要求磁铁供电电源的稳定度好于0.02%,这里电源稳定度的定义为:rogrammed remote control and monitoring system of a KYS 550A/90V silicon controlled power supply with high current stability is described. The magnetic spectrometer excited by this power supply is used for electron scattering experiment in the medium energy region. With this system, the power supply can be turned on and off by computer or manually, the output current can be set and monitored, the operating condition of the KYS power supply can be displayed and the relevant data can be acquired and processed. The setting resolution of the system is 12 bits. The long-time stability of the output current is improved from the original value of 8×10^(-5)/24h with the local control system to 3×10^(-5)/24h with the remote control system. The system has the following characters: high reliability, small size, low cost and high ratio of performance to cost.
