论文摘要
MDPCT1是在美国磁铁开发计划框架中开发和测试的四层Cos-Theta NB3SN偶极示威者。在第一次测试中，磁铁在4.5 k时达到14.1 t的加速器磁体的记录场，在第二次测试中为1.9 k时14.5 t，然后显示出较大的降解。尽管其内部线圈的表现异常出色，只有两次淬火可达14.5吨，没有降解的证据，但在测试过程中，外围线圈降解。通过在FNAL上采用新的测量和分析技术，我们将详细讨论发生了什么。讨论了我们的诊断中的成功和失败。在两个测试过程中的技术的演变（和三个热周期）显示了解决FNAL测试的第一个四层磁铁所带来的挑战的途径。本文介绍了淬灭数据的分析以及诊断功能和互补测量，以支持磁铁性能分析。
MDPCT1 is a four-layer cos-theta Nb3Sn dipole demonstrator developed and tested at FNAL in the framework of the U.S. Magnet Development Program. The magnet reached record fields for accelerator magnets of 14.1 T at 4.5 K in the first test and 14.5 T at 1.9 K in the second test and then showed large degradation. While its inner coils performed exceptionally well with only two quenches up to 14.5 T and no evidence of degradation, the outer coils degraded over the course of testing. By adopting new measurement and analysis techniques at FNAL we are discussing in detail what happened. Both success and failure in our diagnostics are discussed. The evolution of techniques over the course of two tests (and three thermal cycles) shows the path to address challenges brought by the first four-layer magnet tested at FNAL. This paper presents the analysis of quench data along with diagnostic features and complementary measurements taken in support of the magnet performance analysis.
