摘要
采用特殊工艺制作了 HIRFL-CSR电子冷却装置冷却段高精度螺线管线圈 ,两个产生反向磁场的线圈同轴、平行地放置在特制的测量装置上 ,高精度霍尔探头位于测量装置中心平面上 ,探头测量面与测量装置轴线重合 ,测量单个线圈磁场的横向分量 ,调节线圈几何轴相对于测量装置轴线的夹角 ,测得线圈磁轴的偏角小于 1× 1 0 -3。
The prototypes of high precision solenoid coils in electron cooling device of HIRFL CSR were fabricated by special techniques. Two coils were placed in two parallel, concentric planes, the lower coil was fixed, and the upper coil can rotate concentrically. The transverse component of magnetic field of each coil was measured with the high resolution Hall sensor. The deviation between magnetic axis of coils and geometric axis of reference plane was less than 1×10 -3 after adjustment. The device meets the equirement of a magnetic field with a depth of parallelism better than 1×10 -4 .
