AMS-100 - The next generation Magnetic Spectrometer in Space
Stefan Schael(Rheinisch Westfaelische Tech. Hoch. (DE))
The next generation magnetic spectrometer in space, AMS-100, is designed to have a geometrical acceptance of 100 m2 sr and to be operated for at least ten years at the Sun–Earth Lagrange Point 2. Compared to existing experiments, it will improve the sensitivity for the observation of new phenomena in cosmic rays, and in particular in cosmic antimatter, by at least a factor of 1000.
The magnet design is based on high temperature superconductor tapes, which allow the construction of a thin solenoid with a homogeneous magnetic field off 0.5 Tesla inside. The inner volume is instrumented with a silicon tracker that enables the magnetic spectrometer to separate protons from anti-protons up to energies of 70 TeV and a calorimeter system that is 70 radiation lengths deep, equivalent to four nuclear interaction lengths, which extends the energy reach for cosmic-ray nuclei up to the PeV scale, i.e. beyond the cosmic-ray knee. Covering most of the sky continuously, AMS-100 will detect high-energy gamma-rays in the calorimeter system and by pair conversion in the thin solenoid, reconstructed with excellent angular resolution in the silicon tracker.
Since the publication of the detector concept in 2019 a lot of progress has been made on the technical concept of the instrument which will be presented.
