Towards the first superconducting magnet in space
In space, high-field superconducting magnets based on high temperature superconductive (HTS) materials can have several promising applications: from very high resolution astroparticle spectrometry, to active shielding to protect astronauts from harmful radiation, and even debris removal.
One leading project in this field is the HTS Demonstrator Magnet for Space (HDMS), developed with the Italian Space Agency (ASI), the University of Trento, TIFPA and INFN Milano. In the event of a successful demonstration, a scaled-up model could be integrated into a space experiment to become the first ever superconducting magnet for space.
ARCOS (Astroparticle Research Compact Orbital Spectrometer) is a conceptual compact magnetic spectrometer operating in space. Gathering the same partners, it relies on the development of a high-field HTS magnet system suitable for long-term operation in space. An HTS demonstrator coil for the ARCOS magnet is being built within the HDMS project.
The ARCOS magnet is a 12-coil toroidal HTS magnet for a proposed next-generation magnetic spectrometer in space.
AMaSED-2 is a demonstrator magnet for a single coil pack of the ARCOS magnet and it contains two pancake coils.
- The pancake layers of AMaSED-2 have a racetrack-like shape, where circular arcs with a small curvature replace the straight parts of the racetrack shape to ensure contact between successive winding turns.
- The cable used is a two-tape stack in face-to-face configuration of 12 mm wide HTS tape.
- Each pancake coil is wound without turn-to-turn insulation to obtain self-protection against quenching.
- An inner copper band transfers the current between HTS tape and copper over the entire circumference of the innermost winding turn and functions as layer jump to the other pancake coil.
- An outer copper band functions as current lead and transfers the current between copper and HTS tape over the entire circumference of the outermost winding turn.
- The mechanical structure is made from aluminum alloy to be both strong and lightweight.
