The Drift Chamber detector of the FOOT experiment: Performance analysis and external calibration

The study that we present is part of the preparation work for setup FOOT (FragmentatiOn Of Target) experiment whose main goal measurement double differential cross sections fragments produced in nuclear interactions particles with energies relevant particle therapy. focused on characterization gas-filled drift chamber detector composed 36 sensitive cells, distributed over two perpendicular views. Each view consists six consecutive and staggered layers three cells per layer. We investigated efficiency performed an external calibration space–time relations at level single cells. This information was then used to evaluate resolution. An tracking system realized microstrip silicon detectors adopted have a track independent chamber. proton beam 228 80 MeV. overall hit detection has been found be 0.929±0.008, energy. spatial resolution central cell about 150±10 μ m 300±10 corresponding angular measured 1.62±0.16 mrad 2.1±0.4 higher lower energies, respectively. In addition, best value intrinsic evaluated range 60−100 m. framework experiment, will pre-target region, exploited measure projectile direction position, as well identification fragmentation events.
