The SHADOWS (Search for Hidden And Dark Objects With the SPS) experiment is one of three proposed detectors for installation in the ECN3 SPS beam dump in the North Area at CERN. SHADOWS would search for a large variety of feebly-interacting particles (FIPs) created in the dump of the 400 GeV SPS proton beam. SHADOWS is placed off axis in order to reduce background from the beam, which also allows it to co-exist with the proposed HIKE (High Intensity Kaon Experiment) experiment. The proposed SHADOWS detector consists of: an upstream veto, a Magnetized Iron Block lateral veto, a 20 m decay volume, a tracking system utilizing the magnetic field produced by a dipole magnet, a timing system, an electromagnetic calorimeter, and a muon system. SHADOWS will allow the exploration of a large parameter space for many FIPs—such as light dark scalars, axion-like particles, and heavy neutral leptons with, masses ranging between 0.1 and 5 GeV. It might also be complemented by a dedicated neutrino experiment (NaNu@SHADOWS) which would extend the physics reach by studying tau-neutrino events. This talk will provide an overview of SHADOWS, including a brief status of FIP searches, and then focus on the detector technologies and challenges involved.

Coffee will be served at 10:30. .
