论文摘要
训练加速器磁铁是一个昂贵且耗时的过程。因此，训练淬灭的数量必须减少到最低。我们在小型实验中研究了浸渍的NB3SN卢瑟福电缆的培训。该测试涉及一条在模拟倾斜cosine-theta（CCT）线圈环境的蜿蜒通道中浸渍的卢瑟福电缆。样品是使用变压器供电的，洛伦兹力是由外部施加的磁场产生的。低材料和氦消耗可以测试大量样品。在本文中，我们介绍了用氧化铝填充的环氧树脂，具有石蜡样的机械性能的修饰树脂以及在苏黎世Eth Zourich开发的新的坚硬树脂的培训。将这些新数据与先前发布的结果进行了比较。与具有未填充的环氧树脂的样品相比，充满氧化铝的环氧树脂的人在达到临界电流的80％之前，显示出具有较高初始淬火淬火淬火淬火的训练特性。
Training of accelerator magnets is a costly and time consuming process. The number of training quenches must therefore be reduced to a minimum. We investigate training of impregnated Nb3Sn Rutherford cable in a small-scale experiment. The test involves a Rutherford cable impregnated in a meandering channel simulating the environment of a canted-cosine-theta (CCT) coil. The sample is powered using a transformer and the Lorentz force is generated by an externally applied magnetic field. The low material and helium consumption enable the test of a larger number of samples. In this article, we present training of samples impregnated with alumina-filled epoxy resins, a modified resin with paraffin-like mechanical properties, and a new tough resin in development at ETH Zürich. These new data are compared with previous results published earlier. Compared to samples with unfilled epoxy resin, those with alumina-filled epoxy show favorable training properties with higher initial quench currents and fewer training quenches before reaching 80% of the critical current.
