Testbeam Performance and Signal Yields of Prototypes for the SHiP SBT — •Fairhurst Lyons for the SHiP-SBT collaboration — University of Freiburg, Freiburg, Germany

We present R&D towards the surrounding background tagger (SBT) of the Search for Hidden Particles (SHiP) experiment, a general-purpose detector housed at the CERN SPS accelerator to search for light, feebly interacting particles. This is a large-area detector for energy reconstruction and tracking, which consists of many individual cells filled with liquid scintillator. Each cell is equipped with two wavelength-shifting optical modules (WOMs) that capture scintillation light and transfer it to silicon photomultipliers. Multiple such cells with different detector materials were tested at a CERN SPS µ⁻ testbeam; analysis of performance and comparison with simulation will be presented here.
