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, FASER$ν$, 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 will start taking LHC collision data in 2022, and will run throughout LHC Run 3.

  1. The first observation of neutrinos at CERN's Large Hadron Collider 2 comments

    • The Wikipedia article is a decent intro to the general challenge: https://en.wikipedia.org/wiki/Neutrino_detector The paper this article is referencing includes a citation to a much longer paper about FASER itself that explains more about how it is designed and why…

    • The experiment is described in this[1] article. Relevant quote: The detector is positioned on the beam collision axis line-of-sight (LOS) 480 m from the ATLAS collision point (interaction point 1, IP1) in an unused service tunnel, TI12. [...] A huge number of neutrinos are…
