Abstract The FAIR Project – a new international Facility for Antiproton and Ion Research is under construction in Darmstadt, Germany. The core machine at FAIR is the SIS100 synchrotron which utilises superconducting magnets in order to guide the heavy ion beam. The bending component of the magnetic field is generated by super-ferric window-frame dipole magnets symmetrically distributed over the six arc sections of the accelerator ring. The dipole coils are wound with a LTS low AC loss Nuclotron-type cable. Due to the very thick inter-turn insulation, the coil is characterized by a strong anisotropy of thermal conductivity which enables application of a 1D electro-thermal model. This work presents the latest version of the magnet model used for the simulation of magnet’s operating modes at the test facility (including quench). Since currently the series dipole magnets undergo acceptance tests at cryogenic conditions, the simulation results are compared to the available measurements.

SIS100 超导偶极磁铁的电热一维模型

摘要 FAIR 项目——一个新的国际反质子和离子研究设施正在德国达姆施塔特建设。FAIR 的核心机器是 SIS100 同步加速器，它利用超导磁体来引导重离子束。磁场的弯曲分量由对称分布在加速器环的六个弧段上的超铁窗框偶极磁铁产生。偶极线圈用 LTS 低交流损耗 Nuclotron 型电缆缠绕。由于匝间绝缘非常厚，线圈的特点是具有很强的热导率各向异性，从而可以应用一维电热模型。这项工作展示了最新版本的磁铁模型，用于在测试设施（包括失超）模拟磁铁的操作模式。
