Polyethylene naphthalate as alpha and heavy nucleus detection material — •Kim Tabea Giebenhain, Hans-Georg Zaunick, Roman Bergert, and Kai-Thomas Brinkmann — Justus-Liebig Universität, Gießen, Germany

Polyethylene naphthalate (PEN) is a material with intrinsic scintillation capabilities. Using a thin film of PEN read out by SiPM photo sensors has shown to be an excellent detector for alpha particles with potential applications for alpha spectroscopy. Measurements with alpha sources were conducted to determine the achievable energy resolution. Furthermore, optimization of the detector by means of optical surface coating was studied and results will be discussed.
