Efficiency and time resolution of a large-size WOM-SiPM-based liquid-scintillator detector — •Alessia Brignoli for the SHiP-SBT collaboration — Humboldt Universität zu Berlin

Within the BMBF-funded generic R&D consortium High-D, a multi-cell large area liquid-scintillator detector, where each cell is equipped with two wavelength-shifting optical modules (WOMs) viewed by a ring-array of silicon photomultipliers (SiPMs) is being developed. The aim is to reconstruct particles crossing the detector using the time and light-yield response. Such a detector type has been proposed for the Surround Background Tagger for the SHiP experiment proposal at the CERN SPS. In a first step, we are studying the characteristics of a one-cell detector using data taken during a testbeam campaign in October 2022 with a positron beam at the DESY testbeam facility in Hamburg. We will present results on the detector cell efficiency as well as on the time resolution of the detector as function of particle beam position at the detector cell.

We acknowledge the support from BMBF via the High-D consortium.
