Detector Response of a Liquid-Scintillator Detector Prototype with WOM and SiPM Readout — •Linus Shihora for the SHiP LScin SBT collaboration — HU Berlin, Berlin, Deutschland

SHiP is a proposed beam dump experiment at CERN to search for very weakly interacting new particles with a mass between 0.1 GeV - 10 GeV. Hadrons from proton-proton collisions are absorbed and muons redirected through a magnet system. This leaves only neutrinos and other neutral particles to decay in the 50m long decay volume. This decay volume will be surrounded by scintillating liquid (Surrounding Background Tagger = SBT) to reduce background. The scintillation photons will be detected using wavelength-shifting optical modules coupled to an array of silicon photomultipliers.

This talk will analyse and discuss the detector-response of a new and improved liquid-scintillator detector, tested at the CERN PS accelerator in 2018, and compare the results to previous measurements performed in 2017 with a smaller liquid-scintillator detector.
