Publisher Summary This chapter explores the Alpha Magnetic Spectrometer (AMS), which is a particle physics experiment module for use on the International Space Station (ISS). The AMS experiment is designed to examine the fundamental physics of the universe, in particular through the search of antimatter and dark matter. At the heart of the detector is a large superconducting magnet system cooled to a temperature of 1.8 K by 2500 liters of superfluid helium: both the magnet and cryogenic systems are currently under construction by Space Cryomagnetics Ltd of Culham, England. The magnet consists of 14 superconducting coils arranged around the 1 m diameter warm bore. A special test facility has been designed and constructed which allows the AMS superconducting magnet coils to be tested individually in a cryogenic environment which approximates to conditions on the International Space Station. The twelve racetrack (flux return) coils have been tested at currents exceeding the assembled magnet current, to simulate the mechanical loadings in service. Quench testing has also been performed on each coil to check the operation of the quench heaters and the stability of the coils. |
