摘要
给出了波荡器位相误差的函数式，可由磁场峰值分布直接计算波荡器位相均方根误差。给出了波荡器垫补修正场的简单解析计算式，可根据垫片的位置、大小、厚度、磁极间隙等参数直接计算出对磁场及位相的修正。
Undulator rms phase error is expressed as function of the magnet peak field distribution. It can be used as the objective function for practical undulator performance optimization. An simple analytical computation formula is given for field signature of the shims to predict the field and phase perturbation according the shim position, size, thickness and magnet gap.
