High time and energy resolution semi-transparent scintillation detectors for application in γ optics and Mössbauer spectroscopy

Recently, phenomena as a quantum entanglement, Raabi oscillations, a stimulated emission etc. have been expanded into short wavelengths, namely X-rays and the γ radiation. However, this brings new requirements for detection systems, especially for their time resolution and energy selectivity. In this article, two partially transparent scintillation detectors for the characterization of a gamma-photon beam are presented. The first detector is a partially transparent scintillation detector with the time resolution less than 10ns. The second detector is a partially transparent scintillation detector utilizing Mössbauer effect with the energy selectivity up to 20.2neV. The unique design of these detectors is possible due to the use of the YAP:Ce powder, which allows the preparation of the custom-shaped scintillators with tunable absorption properties. Using these detectors together in synergy makes them a comprehensive tool for the characterization of gamma photons both in the energy and time domain.
