摘要
合肥相干谐波辐射实验装置的主体部分是光学速调管。为提高实验用电子束能量,将原光学速调管的对称结构改造为不对称结构。原光学速调管三段各自的积分场都很大,总的积分场很小,三段不能独立可调。改造后的光学速调管需要三段独立可调,每段的积分场都必须很小。对改造后保留的辐射段磁场进行垫补和调试,使它的积分场和相位误差得到了有效减小。
The main component of experiment equipment of coherent harmonic radiation in Hefei is optical klystron. To increase the electron beam energy for experiment, the symmetrical configuration of optical klystron was shifted to non-symmetrical configuration. The total integral field of old optical klystron is small, but the magnetic gaps of the three sections are not adjusted solely. After reconstruction, the three sections must be adjusted solely, so the integral field of every one section must be much small. The magnetic field distribution of undulator of radiation section was shimmed and the integral field. The optical phase error is decreased effectively after shimming.
