摘要: 介绍了兰州重力加速器冷却储存环实验环二极磁铁积分长线圈测磁装置的构成，描述了实验环二极铁的分散性测量、横向分布测量、传递函数等测量内容及测量方法。实验环二极铁采用不断地加减硅钢铁片垫补和加调整线圈电流的方法来调整二极磁铁的有效长度来改变分散性。通过垫补和测量，二极磁铁的分散性在优化磁场时达到±2×10-4。同时给出了二极铁的横向分布和传递函数的测量结果。对二极铁的设计和加工进行了修正。Abstract: The paper describes the equipment of integral measurement of dipole magnetic field for HIRFL-CSRe and introduces integral field measurement method and content. In order to adjust the effective length of magnet and to improve the dispersivity of the 16 dipole magnets, dispersivity is ceaselessly measured after adding or taking out silicon steel slice or changing current of rectifiable coil. After magnetic padding and measurement, the dispersivity of dipole magnets satisfies the requirement of CSR project. The final measurement result of integral magnetic field distribution and transfer function is given. The magnet design and manufacture are also emended with measurement data.
