-
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1 600 mm、 直径510 mm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8.20 T， 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 injectorⅡhas 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.Abstract: The preliminary test of the superconducting solenoid for ADS injectorⅡhas been carried out in order to measure its performances.
