Performance of the ToF detectors in the foot experiment

Abstract

The FOOT (FragmentatiOn Of Target) experiment aims to determine the fragmentation cross-sections of nuclei of interest for particle therapy and radioprotection in space. The apparatus is composed of several detectors that allow fragment identification in terms of charge, mass, energy and direction. The fragment time of flight (ToF) along a lever arm of ∼2 m is used for particle ID, requiring a resolution below 100 ps to achieve a sufficient resolution in the fragment atomic mass identification. The timing performance of the ToF system evaluated with 12C and 16O beams is reviewed in this contribution.
