北京正负电子对撞机电磁Wiggler专用计算机控制系统

THE COMPUTER CONTROL SYSTEM OF THE ELECTROMAGNETIC WIGGLER AT BEPC

用新研制的PVR电压基准源与51单片机8031组成高精度大电流稳流源的数控系统,对BEPC中的Wiggler装置实现电磁补偿,使电源智能化的同时,又使电源整体稳定度得以改善(从1×10^(-4)提高到2.8×10^(-5))成为BEPC中少见的国产化数控系统。

By using new voltage reference PVR modula and single chip microcomputer, the precise digital control system of the current-stabilized power supply was made. This high grade control system has beew used for the control and compensation of magnetic field of the insertion device Wiggler at BEPC, The result is that not only power supply is intelligentized, but also long-term stability of current is improved.
