The AMS-100 is a proposed next-generation magnetic spectrometer designed for space-based cosmic ray observation at the Sun-Earth L2 point, targeting a 1000-fold increase in sensitivity over current instruments. This advancement would enable direct measurement of cosmic rays up to PeV energies, facilitating searches for dark matter signatures and primordial antimatter.
Key insights
- High-temperature superconducting (HTS) REBCO tapes enable the construction of a large 4-meter diameter magnet for space applications, allowing passive cooling to maintain optimal operating temperatures (50-60 Kelvin) without liquid cryogens.
- The integration of an expandable compensation coil allows the magnetic moment of the solenoid to be balanced, facilitating spacecraft attitude control without propellant consumption.
- The design emphasizes redundancy and complementarity among its multiple detector systems (silicon tracker, calorimeter, etc.) to ensure accurate particle identification and extend measurements into the PeV energy range, complementing multi-messenger astronomy.
