SND@LHC is a compact and stand-alone experiment designed to perform measurements with neutrinos produced at the Large Hadron Collider in a hitherto unexplored pseudo-rapidity region of $7.2 < \eta < 8.6$, complementary to all the other experiments at the LHC.
The experiment is located 480 m downstream of IP1 in the otherwise unused TI18 tunnel.
The detector is composed of a hybrid system based on an 800 kg target mass of tungsten plates, interleaved with emulsion films and electronic trackers, followed downstream by a calorimeter and a muon system.
The configuration allows efficiently distinguishing between all three neutrino flavours, opening a unique opportunity to probe physics of heavy flavour production at the LHC in the region that is not accessible to ATLAS, CMS and LHCb.
This region is of particular interest also for future circular colliders and for predictions of very high-energy atmospheric neutrinos.
The detector concept is also well suited to searching for Feebly Interacting Particles via signatures of scattering in the detector target.
In the first phase the detector will operate throughout LHC Run 3 to collect a total of $290\,\text{fb}^{-1}$.
The experiment was approved by the Research Board at CERN in 2021, and it is currently taking physics data.
