The SND@LHC detector experiment is located at the Large Hadron Collider (LHC), about 480 m downstream of the ATLAS interaction point. The detector is designed to measure, for the first time ever, high-energy neutrinos produced at the LHC in the pseudorapidity region of 7.2<η<8.4, which is inaccessible to other LHC experiments. The detector comprises a hybrid system that incorporates multiple components. The detector includes a 830 kg target composed of tungsten plates arranged in alternating layers with nuclear emulsion and electronic trackers: this arrangement functions as an electromagnetic calorimeter. Following the electromagnetic calorimeter, there is a hadronic calorimeter and a muon identification system. The detector possesses the ability to differentiate interactions involving all three neutrino flavours, enabling investigations into the physics of heavy flavour production in the forward region. This research is particularly significant for future circular colliders and high-energy astrophysical neutrino experiments. Furthermore, the detector has the ability to search for the scattering of Feebly Interacting Particles. The detector started operating during the LHC Run 3, and it collected a total of ∼39 fb−1 in 2022. The detector aims to collect approximately 250 fb−1 in the whole of Run 3.
