Usage of PEN as self-vetoing structural material in the LEGEND-1000 experiment — •Luis Manzanillas Velez for the PEN collaboration — Max-Planck-Institut für Physik

PEN is an industrial polyester plastic interesting for the physics community as a new type of wavelength shifting plastic scintillator. Recently, PEN structures with good radiopurity and attenuation length have been successfully produced using the injection compression moulding technology. This opens the possibility for usage of PEN as optically active structural components in low-background experiments such as the LEGEND experiment. The ongoing R&D on PEN will be outlined with focus on the evaluation of the optical properties PEN. In addition, the ongoing efforts for application of PEN in the LEGEND-1000 experiment will be presented.
