Abstract
SND@LHC is a compact and stand-alone experiment to perform measurements with neutrinos produced at the LHC in the pseudo-rapidity region of $7.2 < \eta < 8.6$, complementary to all the other experiments at the LHC.
The experiment will be located 480 m downstream of the ATLAS interaction point, in the unused TI18 tunnel. The detector is composed of a hybrid system based on an 800 kg target mass of tungsten plates, interleaved with emulsion 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.
The detector concept is also well suited to searching for Feebly Interacting Particles via signatures of scattering in the detector target.
The data acquisition system is based on a custom board and front-end electronics which operates in a trigger-less fashion, by sending all recorded hits to a central server, where online event building and noise suppression is performed.
The detector is currently being commissioned in the SPS testbeam area and will be installed in the TI18 tunnel by the end of 2021. The first phase aims at operating the detector throughout LHC Run 3 to collect a total of 150 fb$^{-1}$
