Results from parabolic flight campaigns using a compact scintillation detector — •Roman Bergert, Dzmitry Kazlou, Hans-Georg Zaunick, and Kai-Thomas Brinkmann — 2nd Physics Institute, Justus Liebig University Giessen
A compact, low-power scintillation detector designed for environmental radiation monitoring and dosimetry applications will be presented. The detector utilizes an EJ-276D plastic scintillator, which possesses good pulse-shape discrimination (PSD) characteristics, thereby facilitating effective particle identification.
The detector signal readout is performed using a Red Pitaya STEMLab 125-14 platform serving as a high-speed digitizer (125 MS/s, 14 bits resolution), combined with a bespoke high.voltage bias supply and a dual-channel silicon photomultiplier (SiPM) analog front-end readout.
The two-channel analog front-end provides a high-gain path that is optimized for high resolution in the low-energy range, as well as a low-gain path that covers the high-energy range, thereby ensuring a higher dynamic range.
The fully integrated system is lightweight (<1 kg), compact (12 cm x 9 cm x 6 cm), and low-power (<8 W), rendering it highly suitable for portable, battery-powered, or autonomous operation.
The detector assembly performance was evaluated during multiple parabolic flight campaigns, during which the detector operated autonomously in mixed radiation fields, acquiring complete signal waveforms for subsequent offline PSD analysis. The results are taken to discuss the feasibility of our compact, PSD-capable detector for future radiation monitoring and dosimetry missions.
