Description
Energetic charged-particle environment can be monitored and spectroscopically analyzed with newly developed copper-halide thin-film scintillators. These films are synthesized of perovskite materials that exhibit strong blue luminescence even in polycrystalline form. This provides facile and low-budget production technology, structural flexibility and stability, as well as high tolerance to extreme temperatures. Their spectroscopic precision is comparable or better than the majority of commercial scintillator materials, which property is even more remarkable for energetic heavy ions. The thin-film form, as an unusual solution, has the advantages of insensitivity to background gamma-rays and the opportunity of constructing multilayer scintillation units basically following the operational concept of a phoswich detector. The radiation hardness of the copper-halide films has also been assessed with accelerated proton beams, revealing their exceptional tolerance to high radiation fields. A modular detector can be optimized for missions requiring miniaturized instruments with low-power consumption, as well as offers durable operation in hostile environments targeting space weather monitoring, solar activity and planetary exploration. Scintillation characteristics, tolerance tests and application concepts will be presented.
