耐高辐照铝基低温超导卢瑟福电缆研制

Development of high radiation resistant aluminum-stabilized low temperature superconducting Rutherford cable

中国科学院高能物理研究所提议在中国散裂中子源上建设高性能的实验型缪子源,用于研究缪子科学、中微子物理和下一代高强度缪子、中微子加速器装置的关键技术。俘获超导磁体是实验型缪子源的重要组件之一。俘获磁体在高通量辐照下运行,需要采用耐高辐照的铝基超导卢瑟福电缆绕制线圈。经过上百次的试验,目前成功研制了三根1 500米级的超导电缆,其机械性能和电性能满足俘获磁体需要。

An advanced Experimental Muon Source(EMuS) was proposed at China Spallation Neutron Source(CSNS) in Dongguan for muon science, neutrino physics and for R&D of key technologies related to next generation high power muon/neutrino accelerator by the Institute of High Energy Physics(IHEP). The capture superconducting magnet is one of the key components of the EMuS. The superconducting coil of the capture magnet should be wound by high radiation resistant aluminum-stabilized superconducting Rutherford cable for its high flux irradiation operation condition. After hundreds of tests, three pieces of superconducting cables with 1500 meters were successfully developed, and their mechanical and electrical properties meet the requirements of the capture magnet.
