Ams, 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 کاملThe AMS-02 detector operation in space
The Alpha Magnetic Spectrometer is a large acceptance instrument conceived for the search of primordial anti-matter and dark matter on board the International Space Station (ISS) orbiting at ∼400 km from the earth surface. Nine layers of double sided silicon microstrip detectors track with a single point resolution of 10 µm the charged particle trajectories bent in the magnetic field of a perma...
متن کاملThe 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 کاملSearch for Antimatter with the AMS Cosmic Ray Detector
Antimatter search results of the Alpha Magnetic Spectrometer (AMS) detector are presented. About 10 triggers were collected in the 1998 precursor flight onboard space shuttle Discovery. This ten day mission exposed the detector on a 51.7◦ orbit at an altitude around 350km. Identification of charged cosmic rays is achieved by multiple energy loss and time-of-flight measurements. Bending inside t...
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...
