Plastic Scintillator and Light Guide Research and Development — •Patrick Deucher — Johannes Gutenberg Universität Mainz

Plastic scintillators are broadly used in physics experiments for the detection of particles and electromagnetic radiation. With tunable emissive properties and a fluorescent decay time of a few ns, plastic scintillators are a solid option that can be tailored to individual applications. First steps for the production and optimization of polystyrene based plastic scintillators have been taken at the Johannes Gutenberg University in Mainz. This includes the purification of styrene, the addition of different fluorophores and thermal polymerization. In cooperation with Tübingen, we develop dedicated active light guides for use with large SiPM arrays. Moreover, plastic scintillators with optimized capability for pulse-shape discrimination are investigated for use in the ECAL of the DUNE Near Detector. This talk will present the progress on plastic scintillator production and characterization including absorption, emission and lifetime measurements of first samples. This work is supported by funds of the Excellence Cluster PRISMA+.
