Development of new or optimization of already widely used scintillation materials for high-energy physics applications has become a very important research activity during the last decade. There are presently several detector concepts in consideration that are based on organic scintillator material for fast timing of charged particles or sampling calorimeters. In recent years, the widely used organic material polyethylene naphthalate (poly(ethylene 2,6-naphthalate) or PEN) was discovered and intensively studied as a potential cost-effective plastic scintillator. We tested a set of PEN samples produced by injection molding in the framework of R&D towards the LEGEND project for the search of neutrinoless double beta decay. The material was evaluated through the measurement of changes of the optical transmittance under irradiation with 60Co photons, light yield and scintillation kinetics parameters at different temperatures. The paper will report on the obtained results.
We acknowledge support by BMBF via the High-D consortium.
