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 produced in LHC collisions via hadron decays, and their flux is collimated along the beam collision axis. So what they did differently is to place the detector in a spot which has much higher neutrino flux than your average spot on earth. Thus the small detector volume is compensated for by having more neutrinos pass…

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: https://arxiv.org/pdf/2207.11427.pdf The gist of it seems to be this was the first attempt to put a neutrino detector n nthe director line of sight of a particle collider where they're produced. The LHC's other detectors have blind spots where the neutrinos are produced. The general challenge with neutrinos is they don't interact…
