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。
This paper introduces the structure of the long loop magnet measuring device for the experimental ring of the cooling storage ring in Lanzhou Gravity Accelerator, and describes the measuring content, measuring method and measurement of dispersivity, lateral distribution and transfer function of the experimental ring diode. Experimental loop diode using continuous addition and subtraction of silicon steel pad pad plus adjust the coil current to adjust the effective length of the two-pole magnets to change the dispersion. By padding and measurement, the dispersivity of the two-pole magnet achieves ± 2 × 10-4 when optimizing the magnetic field. At the same time, the lateral distribution of the diode and the measurement results of the transfer function are given. The design and processing of the diode has been amended.
