R&D of Multidimensional Calorimetry for the SHiP SBT — •Fairhurst Lyons for the SBT collaboration — ALU Freiburg

We present R&D towards a large-area detector for energy reconstruction and limited resolution 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. SHiP allows probing dark photons, dark (pseudo-)scalars, and heavy neutrinos, as well as the investigation of light dark matter, neutrinos, and flavour physics. The SBT studied here surrounds the vacuum decay vessel of SHiP to detect charged particles either entering the vacuum vessel from outside, or produced in inelastic interactions of muons and neutrinos in the vacuum vessel walls. We present studies of readout electronics and simulated individual detector cells investigating scintillator response.
