Testbeam Performance and Light Yields of Prototype Cell for the SHiP SBT — •Fairhurst Lyons for the SHiP-SBT collaboration — University of Freiburg

We present R&D towards 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. This design could serve as the surrounding background tagger (SBT) of the proposed Search for Hidden Particles (SHiP) experiment, a general-purpose detector housed at the CERN SPS accelerator to search for light, feebly interacting particles. One such cell was tested at the DESY e⁻ testbeam in October 2022; analysis of performance and light yields will be presented here. This work is funded by the Federal Ministry of Education and Research.
