Designing a quality assurance setup for the production of PEN scintillator tiles — •Isabelle Schilling, Jens Weingarten, and Kevin Kröninger — TU Dortmund, Lehrstuhl für Experimentelle Physik IV, 44227 Dortmund

The commercially available plastic polyethylene naphthalate (PEN) is interesting for applications in a wide variety of fields of physics due to its emission of easily detectable blue scintillation light without the use of wavelength shifters and its high mechanical stability. The production of PEN samples based on injection molding at the TU Dortmund enables the individual manufacture of different sample sizes and shapes, depending on the requirements on the scintillator.
Besides, the produced PEN samples have comparable stability to copper, which pulls them in the focus of interest for experiments like LEGEND. The tiles could be a part of the detector holder that could simultaneously act as an active signal background veto. To validate the production of scintillator tiles by the injection molding process, the scintillation properties of the produced PEN tiles must be investigated. The use of the tiles as a radiation detector can be validated in various measurements. Based on these measurement results, a quality assurance system for monitoring the production is developed and will be presented in this report.
