The SHiP Liquid Scintillator-Based Surrounding Background Tagger — •Julian Schliwinski for the SHiP LScin SBT collaboration — HU Berlin, Berlin, Deutschland

SHiP is a proposed general-purpose beam dump experiment at the CERN SPS North Area. It is desigend to combine the Search for Hidden Particles (SHiP), e.g. Heavy Neutral Leptons (HNL), with the search for light dark-matter particles and studies of tau neutrino physics.

Proton-proton Collisions with the SPS' 400 GeV beam on the fixed target may create very weakly interacting new particles with a mass between 0.1 GeV - 10 GeV. Hadrons from these collisions are absorbed and muons redirected through a magnet system. This leaves only neutrinos as well as other neutral particles to decay in the 50 m long decay volume, which is followed by a magnetic spectrometer and calorimeter. The decay volume will be surrounded by scintillating liquid (Surrounding Background Tagger - SBT) to reduce background. The scintillation photons may be detected using wavelength-shifting optical modules coupled to large-area silicon photomultipliers.

This talk will give an overview of the current design and ongoing R&D on the SBT. Results of test beam measurements with a new and improved liquid-scintillator detector will be presented with a focus on readout electronics and the SiPM photo sensors.
