Abstract
In this Letter, the authors present a design study on YAG:Ce scintillator plates with a microstructured and coated surface. The goal of the study is to improve the outcoupling efficiency and to optimize the directionality of the scintillation light with respect to indirect image detection in the extreme ultraviolet spectral range (5â50 nm wavelength). In a geometric optical simulation, a gain in outcoupling efficiency by over a factor of 4 is shown while the directionality of the scintillation light is improved with respect to state-of-the-art plane scintillator plates.
