    Tracker

    Tracker The FASER tracker has been designed to separate and detect two high-energy, oppositely charged tracks originating from a common vertex in the decay volume. For this purpose, three tracking stations are employed, which are separated by two 1 m-long magnets deflecting the charged particle trajectories. The first tracking station is situated right after the…

    Magnets

    Magnets To achieve sufficient separation of pairs of oppositely charged, high-energy Standard Model particles originating from decays of new physics particles, FASER is equipped with strong magnets designed and manufactured by the CERN magnet group to fulfill technical requirements dictated by the architecture of the TI12 tunnel. FASER uses 0.55 T permanent dipole magnets (see…

  • Scintillators

    Scintillators

    Scintillators The FASER experiment has four scintillator stations that are used to veto charged particles entering the decay volume from the direction of the ATLAS IP. These are used for both triggering and inducing preshowers. The first two stations are the veto stations located in front of the dipole magnets and are primarily used to…
