The AMS-100 experiment: The next generation magnetic spectrometer in space

Abstract

The next generation magnetic spectrometer in space, AMS-100, is designed with a geometrical acceptance of 100 m2sr for a ten year operation at Sun–Earth Lagrange Point 2. The purpose of AMS-100 is to improve the sensitivity for the observation of new phenomena in cosmic rays by at least a factor of 1000 compared to AMS-02.The AMS-100 detector consists of a high temperature superconducting solenoid, an electromagnetic calorimeter, a tracking system made out of silicon and scintillating fibre modules and a time-of-flight system based on plastic scintillators readout by silicon photomultipliers.We will present the AMS-100 project. In the framework of the related R & D-programme, measurements with a test coil made out of 8 layers HTS tape will be shown. Time resolution measurements with a ToF-prototype in the temperature range of +30°C to −40°C will be discussed. The first produced 12-layer fibre mat made out of 125μm thick scintillating fibres and the quality control measurements will be shown.
