Spatial coherence of synchrotron radiation degraded by grating monochromators
Ruslan Khubbutdinov, Gianluca Geloni, Evgeny Saldin +1
In this work, we present a physical and theoretical description of the significant degradation of X-ray spatial coherence properties due to the use of grating monochromators at syn…
