Reverse undulator taper is a unique method allowing to strongly suppress radiation intensity at the exit of SASE undulator while maintaining microbunching at a significant level. Recently, it was used to generate high-purity circularly polarized radiation from dedicated afterburners (Apple-X at the European XFEL and Apple-III at FLASH, the latter operates at the 3rd harmonic of SASE undulator).

The detection of ionizing radiation is at the heart of many strategic applications in both science and technology, including high-energy/particle physics, space exploration, medical diagnostics, border security, and industrial and environmental monitoring. In all such areas, indirect detectors are frequently used, that include scintillating materials converting the energy deposited by ionizing radiation into UV or visible photons, which are then turned into electrical signals by coupled photodetectors.Scintillation light originates from radiative transitions at intrinsic centers or dopants used as activators: therefore, a fast and efficient transport to the luminescent centers of carriers generated upon the interaction between ionizing radiation and the scintillating material is fundamental in the scintillation process.
