Conceptual design of a high temperature superconducting magnet for a particle physics experiment in space

In the frame of a collaboration between CERN, ASI, University of Trento, and TIFPA, the HTS demonstrator magnet for space project has started to define methods and procedures for manufacturing high temperature superconducting magnets for space applications. To this purpose, we developed a conceptual design of a superconducting magnetic spectrometer for a physics experiment in space. The configuration is a toroid with twelve superconducting coils based on ReBCO tape. By using ReBCO tape with an engineering critical current density, J e, exceeding 1000 A mm−2 at and , as reached in the H2020-ARIES program, the magnet system provides an average bending strength of . This is sufficient to measure charged particles with rigidities up to , more than two orders of magnitude higher than the present state-of-the-art space spectrometer. The magnet system requires about of ReBCO tape and produces a peak magnetic field of at an operating temperature of . A small scale single coil, which is about one third in size of a coil from the toroidal magnet system, will be manufactured and tested as demonstrator of the magnet technology. The mechanical structure and performance of the toroidal magnet system and demonstrator coil are described.
