Two-Dimensional Beam Size Measurements with X-Ray Heterodyne Near Field Speckles / Siano, Mirko (Milan U.) ; Butti, Daniele (CERN) ; Goetz, Alexander (CERN) ; Iriso, Ubaldo (CELLS - ALBA, LLS) ; Lefèvre, Thibaut (CERN) ; Mazzoni, Stefano (CERN) ; Nosych, Andriy A (CELLS - ALBA, LLS) ; Paroli, Bruno (Milan U.) ; Potenza, Marco A C (Milan U.) ; Solano, Eduardo (CELLS - ALBA, LLS) et al.
We report on 2D beam size measurements with a novel interferometric technique named Heterodyne Near Field Speckles, capable of resolving few-micrometer beam sizes. It relies on the interference between the weak spherical waves scattered by a colloidal suspension and the intense transilluminating X-ray beam. [...]

Two-dimensional electron beam size measurements with x-ray heterodyne near field speckles / Siano, M (Milan U. ; INFN, Milan) ; Paroli, B (Milan U. ; INFN, Milan) ; Potenza, M A C (Milan U. ; INFN, Milan) ; Teruzzi, L (Milan U. ; INFN, Milan) ; Iriso, U (CELLS - ALBA, LLS) ; Nosych, A A (CELLS - ALBA, LLS) ; Solano, E (CELLS - ALBA, LLS) ; Torino, L (CELLS - ALBA, LLS) ; Butti, D (CERN) ; Goetz, A (CERN) et al.
In this paper we report on recent two-dimensional (2D) electron beam size measurements with a nonconventional synchrotron radiation interferometric technique based on x-ray heterodyne near field speckles (HNFS). The method relies on Fourier analysis of the random speckle patterns generated by a water suspension of nanospheres to assess the full 2D transverse coherence of the incoming x rays. [...]

Simulation Methods for Transverse Beam Size Measurements Using the Heterodyne Near Field Speckles of Hard X-rays / Goetz, Alexander (CERN) ; Butti, Daniele (CERN) ; Iriso, Ubaldo (CELLS - ALBA, LLS) ; Mazzoni, Stefano (CERN) ; Nosych, Andriy (CELLS - ALBA, LLS) ; Paroli, Bruno (Milan U.) ; Potenza, Marco (INFN, Milan ; Milan U.) ; Siano, Mirko (Milan U.) ; Teruzzi, Luca (Milan U.) ; Torino, Laura (CELLS - ALBA, LLS) et al.
The Heterodyne Near Field Speckles (HNFS) is a special type of interferometry technique where radiation is scattered by nanoparticles suspended in a medium. The scattered waves and the transmitted radiation form an interference pattern, which is modulated by the spatial coherence of the radiation and by the scattering properties of the nanoparticles.
