Test Beam Measurements with a Liquid-Scintillator Detector Prototype for the SHiP Surrounding Background Tagger — •Ievgen Korol for the SHiP LScin SBT collaboration — HU Berlin, Berlin; Deutschland

The SHiP experiment is proposed as a new general-purpose fixed-target facility at the CERN SPS 400 GeV accelerator complex. Its goal is to search for "hidden particles", such as Heavy Neutral Leptons (HNL), dark photons, axion-like particles etc. The decay volume of the SHIP detector facility will be covered by the Surrounding Background Tagger (SBT) which is based on liquid-scintillator cells read out by either PMTs or SiPMs using the wavelength-shifting optical modules.

The performance of liquid-scintillator detector prototype was studied with e⁻ (20 GeV), µ⁺ (150 GeV) and π⁺ (150 GeV) from the CERN SPS North Area test beams. Details of the beam test setup, data taking and efficiency measurements of the liquid-scintillator prototype will be presented.
