/ Abstract
Abstract The Alpha Magnetic Spectrometer in a precursor version (AMS-01), was flown in June 1998 on a 51.6° orbit and at altitudes ranging between 320 and 390 km , on board of the space shuttle Discovery (flight STS-91). AMS-01 included an Aerogel Threshold Cherenkov counter (ATC) to separate p from e − and e + from p, for momenta below 3.5 GeV /c . This paper presents a description of the ATC counter and reports on its performances during the flight STS-91.
