Spatial coherence of synchrotron radiation.
The spatial coherence properties of a monochromatic component of synchrotron radiation from an insertion device in the Fraunhofer limit are analyzed in the general case when the coherence distance is comparable with the beam width, expressing them by simple products and convolutions of Fourier transforms and autocorrelations on the single-electron field amplitude and the electron-beam position ...
متن کاملCharacterization of spatial coherence of synchrotron radiation with non-redundant arrays of apertures.
A method to characterize the spatial coherence of soft X-ray radiation from a single diffraction pattern is presented. The technique is based on scattering from non-redundant arrays (NRAs) of slits and records the degree of spatial coherence at several relative separations from 1 to 15 µm, simultaneously. Using NRAs the spatial coherence of the X-ray beam at the XUV X-ray beamline P04 of the PE...

متن کاملRecent Trends in Beam Size Measurements using the Spatial Coherence of Visible Synchrotron Radiation
The optical method of measuring the transverse beam profile and size using visible synchrotron radiation (SR) began with simple imaging systems. The resolution was limited by both diffraction and wavefront errors making it difficult to resolve beam sizes less than 50 m. Instead of imaging, an interferometric method for measuring the beam profile and size using spatial coherence was introduced....
متن کاملBRIGHTNESS AND COHERENCE OF SYNCHROTRON RADIATION AND FELs∗
This paper reviews the brightness and coherence properties of radiation from storage rings and free electron lasers (FELs). Starting from the statistical optics and using mutual coherence function of the radiation field, we define the transverse and temporal coherence and modes. Spectral brightness can be represented in radiation phase-space via the Wigner function which is the Fourier transfor...
