Abstract
Abstract
FASER, the ForwArd Search ExpeRiment, is an experiment
dedicated to searching for light, extremely weakly-interacting
particles at CERN's Large Hadron Collider (LHC). Such particles
may be produced in the very forward direction of the LHC's
high-energy collisions and then decay to visible particles inside
the FASER detector, which is placed 480 m downstream of the ATLAS
interaction point, aligned with the beam collisions axis. FASER also
includes a sub-detector, FASERν, designed to detect neutrinos
produced in the LHC collisions and to study their properties. In
this paper, each component of the FASER detector is described in
detail, as well as the installation of the experiment system and its
commissioning using cosmic-rays collected in September 2021 and
during the LHC pilot beam test carried out in October 2021. FASER
has successfully started taking LHC collision data in 2022, and will
run throughout LHC Run 3.
