We introduce an optimized geometry for an X-ray detector named ASCANIO: an innovative 16-channel SDD-based spectrometer purposefully crafted for X-ray fluorescence microscopy (XFM) imaging in synchrotron beamlines. This novel detector adopts a backscattering configuration with a tilted SDD arrangement, achieving a solid angle of 1 sr at a 8 mm sample distance with a potential Output Count Rate exceeding 20 Mcps. With a thickness of 1 mm, the SDD ensures a good absorption efficiency of 65% at 20 keV, all while maintaining an energy resolution of 150 eV at a peaking time of 100 ns thanks to a dedicated cooling system and low-noise front-end electronics.

This novel detector adopts a backscattering configuration with a tilted SDD arrangement, achieving a solid angle of 1 sr at a 8 mm sample distance with a potential Output Count Rate exceeding 20 Mcps. With a thickness of 1 mm, the SDD ensures a good absorption efficiency of 65% at 20 keV, all while maintaining an energy resolution of 150 eV at a peaking time of 100 ns thanks to a dedicated cooling system and low-noise front-end electronics.| File | Dimensione | Formato | |
