为满足上海光源Top-up运行模式的需要
保证光源直线加速器提供稳定的、高品质的束流
研制了次谐波聚束器的低电平控制系统。以可编程逻辑门阵列(FPGA)为基础
利用上下变频、IQ调制解调技术实现了次谐波聚束器幅度和相位的反馈控制。介绍了数字化技术的原理及上层应用程序的开发
并进行桌面测试
实现了幅度控制精度1%、相位控制精度1的技术指标。
To satisfy the Top-up operation mode of Shanghai Synchrotron Radiation Facility(SSRF)
and ensure the linac to provide stable and high current beam bunches
a low level radio frequency(LLRF) control system was developed for sub-harmonic buncher.Based on field programmable gate array(FPGA)
LLRF realized digital amplitude and phase feedback control by using up-down converter
IQ modulator and demodulator techniques.Digital principles and application programs were introduced
and table test was performed.The LLRF system achieved an amplitude control accuracy rate of 1 % and phase control accuracy of 1
well meeting the design requirement.
