Design and Modeling of AMaSED-2: A High Temperature Superconducting Demonstrator Coil for the Space Spectrometer ARCOS

Magnetic spectrometers detect the rigidity of charged particles by measuring the bending of their trajectories as they pass through a magnetic field. ARCOS is a proposal for a next generation magnetic spectrometer in space with a bending strength of 3 T\,m at an operating temperature of 20 K. ARCOS...

Description
Summary:Magnetic spectrometers detect the rigidity of charged particles by measuring the bending of their trajectories as they pass through a magnetic field. ARCOS is a proposal for a next generation magnetic spectrometer in space with a bending strength of 3 T\,m at an operating temperature of 20 K. ARCOS is based on a 12-coil toroidal HTS magnet. Within the HTS Demonstrator Magnet for Space (HDMS) project, we have designed and built AMaSED-2, a small-scale demonstrator coil for the ARCOS magnet. AMaSED-2 consists of two individually built no-insulation HTS ReBCO pancake coils with racetrack-like shapes. The exclusion of electrical insulation material between adjacent winding turns enables self-protection against quenches. The winding blocks are surrounded by copper bands functioning as current leads and layer jumps. AMaSED-2 is supported by a lightweight mechanical structure made from aluminum alloy. We describe the design of AMaSED-2 and present a simple mathematical circuit model for no-insulation coils.
