Research of reproducibility of dipoles for cooler-storage-ring

Abstract

介绍了国家大科学工程HIRFL CSR中主环二极磁铁的分散性测量的原理、测量方法,以及垫补的位置和垫补量与磁铁分散大小的关系. 最后给出了CSR主环二极磁铁最终垫补后的分散性结果、测量误差以及影响测量精度的因素.The measurement method and principle of dipole magnet reproducibility for cooling-storage-ring are introduced. The effects of position and number of steel sheet on the reproducibility of magnet is investigated. The measurements indicate that the reproducibility of CSRm dipoles is less than ± 2 x 10(-4), which can meet the requirements of CSR. In addition, the measurement errors are also analyzed
