The AMS magnetic spectrometer will be installed on the International Space Station ISS to measure the properties of cosmic rays in the range of 1 to 1000 GeV during a mission of three years. A Transition Radiation Detector is used in combination with an electromagnetic calorimeter to reach a rejection of 10(-6) protons against positrons up to an energy of 300 GeV. This allows to search for cosmic cold dark matter through their decay products.

A study of cosmic ray secondaries induced by the Mir space station using AMS-01 Aguilar, M; et. al. (Elsevier BV, 2005-06-01) The Alpha Magnetic Spectrometer (AMS-02) is a high energy particle physics experiment that will study cosmic rays in the similar to 100 MeV to 1 TeV range and will be installed on the International Space Station (ISS) for at least 3 years. A first version of AMS-02, AMS-01, flew aboard the space shuttle Discovery from June 2 to June 12, 1998, and collected 108 cosmic ray triggers. Part of the Mir space station was within the AMS-01 field of view during the four day Mir docking phase of this flight. We have ...
Observation of New Properties of Secondary Cosmic Rays Lithium, Beryllium, and Boron by the Alpha Magnetic Spectrometer on the International Space Station Aguilar, M.; et. al. (American Physical Society (APS), 2018-01-11) We report on the observation of new properties of secondary cosmic rays Li, Be, and B measured in the rigidity (momentum per unit charge) range 1.9 GV to 3.3 TV with a total of 5.4 x 10(6) nuclei collected by AMS during the first five years of operation aboard the International Space Station. The Li and B fluxes have an identical rigidity dependence above 7 GV and all three fluxes have an identical rigidity dependence above 30 GV with the Li/Be flux ratio of 2.0 +/- 0.1. The three fluxes deviate from a sing...
A Deep Learning Approach to Proton Background Rejection for Positron Analysis with the AMS Electromagnetic Calorimeter Hashmani, Raheem Karim; Akbaş, Emre; Demirköz, Melahat Bilge; Department of Computer Engineering (2023-1-26) The Alpha Magnetic Spectrometer (AMS) is a high-precision particle detector onboard the International Space Station containing six different subdetectors. The Transition Radiation Detector and Electromagnetic Calorimeter (ECAL) are used to separate electrons/positrons from the abundant cosmic-ray proton background. The positron flux measured in space by AMS falls with a power law which unexpectedly softens above 25 GeV and then hardens above 280 GeV. Several theoretical models try to explain these phenomen...
Observation of Fine Time Structures in the Cosmic Proton and Helium Fluxes with the Alpha Magnetic Spectrometer on the International Space Station Aguilar, M.; et. al. (American Physical Society (APS), 2018-7-31) We present the precision measurement from May 2011 to May 2017 (79 Bartels rotations) of the proton fluxes at rigidities from 1 to 60 GV and the helium fluxes from 1.9 to 60 GV based on a total of 1 x 109 events collected with the Alpha Magnetic Spectrometer aboard the International Space Station. This measurement is in solar cycle 24, which has the solar maximum in April 2014. We observed that, below 40 GV, the proton flux and the helium flux show nearly identical fine structures in both time and relative ...
High-voltage space tether for enhanced particle scattering in Van Allen belts Danilov, VV; Mirnov, VV; Ucer, D (1999-01-01) New applications of space tethers (High-Voltage Tethered Satellite System project) are discussed in relation with ideal of an active experiment in the Earth's radiation belts. Two conducting strings are supposed to be tethered between the main satellite and two small subsatellites flying through the ERB. A large potential difference similar to 1MV is applied between the tethers by means of a generator carried on the main satellite. The tethers effectively scatter the high energy particles into loss cone of ...
