The Alpha Magnetic Spectrometer (AMS): search for antimatter and dark matter on the International Space Station
The disappearance of cosmological antimatter and the pervasive presence of dark matter are two of the greatest puzzles in the current understanding of the universe. The Big Bang model assumes that, at its very beginning, half of the universe was made out of antimatter. The validity of this model is based on three key experimental observations: the recession of galaxies (Hubble expansion), the h...
متن کاملThe Gamma Ray Detection Capabilities of the Alpha Magnetic Spectrometer
The modeled performance of the Alpha Magnetic Spectrometer (AMS) as a high-energy (0.3 to 100 GeV) gamma-ray detector is described, and its gamma-ray astrophysics objectives are discussed. PACS,
متن کاملSearch for Antimatter in Space with the Alpha Magnetic Spectrometer
The Alpha Magnetic Spectrometer (AMS) is a state of the art particle physics experiment for the extraterrestrial study of antimatter, matter and missing matter. AMS successfully completed the precursor STS91 Discovery flight (June 2nd-12th, 1998), completing 152 orbits at ±52 of latitude and about 400 km of height, collecting more than 100 million CR events. In this paper we report on the first...
متن کاملAms, a Particle Spectrometer in Space
The results of the precursor flight of the AMS experiment are reviewed, the interpretation of the measured proton flux reported, and the prospects for the forthcoming main phase on the International Space Station outlined.
متن کاملPhysics Results from Alpha Magnetic Spectrometer 1998 Shuttle Flight
The Alpha Magnetic Spectrometer (AMS) is a particle detector designed to detect antimatter. During the 10-day test flight on the space shuttle in June 1998, AMS detected 10 events. Upon analysis, no antimatter was found and the antimatter limit was reduced to 1.1 × 10. The proton spectrum shows some differences with the cosmic ray flux used in atmospheric neutrino simulation. A large amount of ...
