Low-absorption, multi-layered scintillating material for high resolution real-time X-ray beam analysis

Author affiliations

Abstract

For online X-ray beam analysis, we introduce a functional device, a multilayer scintillating screen, that succeeds in satisfying three important criteria: high X-ray transparency and high overall efficiency, which are not easily reconcilable using existing devices, as well as high spatial resolution capability. It combines a porous alumina substrate, an optical gold interposer of few nm and an efficient scintillating material (Lu2O3:Eu3+) 450 nm thick. Both layers are deposited using pulsed laser deposition. This multilayer device enables high resolution X-ray imaging while X-ray transparency is preserved to 90% even at 15 keV. Such a device is suitable for real-time X-ray beam analysis at high frequency and is a breakthrough for real-time X-ray beam corrections for most of the synchrotron experiments.
