摘　　要：介绍了加速器驱动次临界系统(ADS)注入器Ⅱ束流聚焦单元超导螺线管的初步测试。该测试在高度1 600mm、直径510mm的垂直杜瓦中,利用型号为cryogenic sms的超导电源对磁体进行了励磁,并利用霍尔探头测试了其轴向磁场分布情况和漏场情况,其中心磁场励磁后可达8.20T,漏场分布和计算值的相对误差小于10%。同时,对励磁过程中骨架的应力应变状态做了测试。对测试结果的分析表明,骨架结构设计合理,应变状态变化平稳,磁体低温稳定性能良好。The preliminary test of the superconducting solenoid for ADS injector tl has been carried out in order to measure its performances. A vertical dewar with height 1 600 mm and outer diameter 510 mm was employed for this test. The magnet was energized by a cryogenic sms superconducting magnet current source. The axial magnetic distribution and leakage field were also tested through hall probes. The center field can be excited up to 8.20 T and the relative diviation between the measured value and the calculated value of the stray and leakage field is less than 10%. The measurements of the strain and stress status of the magnet skeleton show that the distortion is small and the mechanical performance is robust.
