dc.descriptionThe Time-of-Flight (TOF) system of the AMS detector gives the fast trigger to the read out electronics and measures velocity, direction and charge of the crossing particles. The first version of the detector (called AMS-01) has flown in 1998 aboard of the shuttle Discovery for a 10 days test mission, and collected about $10^8$ events. The new version (called AMS-02) will be installed on the International Space Station on March 2004 and will operate for at least three years, collecting roughly $10^{10}$ Cosmic Rays (CR) particles. The TOF system of AMS-01 successfully operated during the test mission, obtaining a trigger efficiency better than 99.9% and a time resolution of 120 ps for protons and better for other CR ions. In addition, the TOF system was able to separate protons from all the other CR nuclei within 1% and to distinguish between downward and upward crossing particles within at most $10^{-8}$.
