Testbeam Performance and Photoelectron Yields of 4-cell Prototype for the SHiP SBT — •Fairhurst Lyons for the SHiP-SBT collaboration — Universitaet 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. Four such cells were tested at a CERN µ− testbeam in October 2023; analysis of performance and photoelectron yields will be presented here.
