The Scattering and Neutrino Detector (SND) at the Large Hadron Collider (LHC), CERN, is an experiment built for the detection of the collider neutrinos. The primary goal of SND is to measure the p+p --> +X process and search for the feebly interacting particles. It will be operational from 2022, during the LHC-Run 3 (2022-2024). SND will be installed in an empty tunnel- TI18 that links the LHC and Super Proton Synchrotron, 480m away from the ATLAS experiment interaction point in the fast forward region and along the beam collision axis.[1][2][3][4][5]
In February 2020, the Search for Hidden Particle (SHiP) collaboration expressed its interest in neutrino-measurement to the LHC Council (LHCC). The letter of intent for SND was presented in August 2020.[6] Based on LHCC’s recommendation, the Letter of intent was followed by the Technical Design report presented in February 2021. The experiment was later approved in March 2021 by the CERN Research Board to be the ninth experiment at LHC.[1][7] In 2023, SND@LHC and FASER reported the first observation of collider neutrinos.[8][9][10]
