Description
We present the construction and characterization of a thin, large area scintillation detector used for a particle telescope project AMORE (Airspace Measurement of Radiation Environment). The instrument aims to observe secondary cosmic rays at during geomagnetic storms, detecting energies and directions of various incoming particles. In this work, we optimized the design and assembly of the ΔE detector part of the telescope. Our study shows how different reflective wrappings influence detected electrons’ and protons’ signal amplitude and position sensitivity. Measurements performed using radioactive sources and monoenergetic protons from the EMON and PIF facilities at PSI determined detector responses at different particle hit positions. The dependence of the total light collection at a given energy deposition on the reflective quality of the wrapping material is also studied. Our results show that the highest reflectivity wrappings correlate with the lowest accuracy of the particle hit position.
