在给定的磁铁安装误差和磁场加工误差的条件下,对兰州重离子加速器冷却储存环主环的闭轨畸变及其校正进行了计算机模拟研究,在典型的误差分布下,校正前的水平方向及垂直方向的最大闭轨畸变分别为3.08mm和2.73mm,校正模拟的结果显示CSRm的闭轨畸变可以控制在足够小的范围内。
Under the condition of given magnet installation error and magnetic field machining error, the computer simulation research on the closed-loop distortion and its correction of the main ring of the cooling storage ring in Lanzhou heavy ion accelerator was performed. Under the typical error distribution, And the maximum vertical track distortion is 3.08mm and 2.73mm respectively. The results of the calibration simulation show that the closed track distortion of CSRm can be controlled within a sufficiently small range.
