摘要
为了使加速器的纳秒脉冲束流稳定,研制了一种高频高压正弦波负反馈系统。利用任意波形信号发生器产生稳定的幅值信号,经过功率放大器输出到加速器聚束系统。设计的天线传感器对功率放大器高频高压信号进行无接触采样。使用存储示波器对信号进行模数变换,数字信号可实现远距离无失真传输。计算机控制程序采用LabView软件编程。通过GPIB接口,计算机接收示波器的测量信号,并对信号发生器进行调节。负反馈系统使功放输出的高频高压信号幅度稳定度达到1%。
To stabilize the nanosecond beam system of an accelerator, a high frequency and high voltage sine wave signal negative feedback system is developed. Steady amplitude signal are produced by arbitrary generators, then the signal are sent to bunching system of the accelerator by a high frequency power amplifier. An antenna sensor designed is used for sampling the high frequency high voltage signal from power amplifier without contacting. Analog digit transition is implemented by a storage oscillograph, and the digit signal can realize lossless transmission at long distance. LabView software is applied to the control program of microcomputer. The microcomputer accepts the test signal from oscillograph and adjusts the amplitude from arbitrary generators through the GPIB bus. 1% amplitude stability of high frequency and high voltage signal from power amplifier is achieved by using negative feedback system.
