Thin Film Scintillators for α-Particle Detection — •Kim Tabea Giebenhain, Hans-Georg Zaunick, and Kai-Thomas Brinkmann — 2nd Physics Institute, Justus Liebig University, Giessen, Germany
Reliable detection of α-particles is one of the core tasks in Radon detection, since relevant Radon isotopes decay by α-emission.
For the development of an efficient and cheap Radon detector, multiple thin scintillator materials were tested to increase the effective area of an existing detector system, while still maintaining a low-cost photodetection setup and good background suppression.
This works present the findings on the light transport of 50 µm thick Polyethylene-Naphthalate foils and thin coatings of scintillating paint EJ-296 on acrylic glass, read out by a dual-SiPM system.
