摘要
针对兰州重离子加速器(HIRFL)的加速器腔体低电平稳定系统的调试与故障检测,设计了单晶体滤波器形式的模拟腔体负载与以数字信号处理为基础的数字模拟负载。对数字模拟负载的组成、实现原理和参数计算等几个方面进行了详细介绍,并给出了设计实物照片与测试频谱图。数字模拟负载可在各种腔体的相位稳定系统与幅度稳定系统的调试中用于模拟各种Q值变化的加速器腔体,并具有模拟腔体的相位调制与幅度调制的能力。
Aiming at the debugging and failure detection of the low-level control system on cavity electric field, the analog simulative electric loads based on single-crystal filter and the digital simulative electric loads based on digital signal processing are designed respectively.The composition, design principle,parameter calculation, etc.of the digital simulative electric load are introduced in detail.The digital simulative electric load can be used to simulate the cavity with variable quality coefficients, phase modulation and amplitude modulation, when debugging phase stabilization and amplitude stabilization in various cavity.
