/ Mazzoni, Stefano (CERN) ; Iriso, Ubaldo (CELLS - ALBA, LLS) ; Kamma-Lorger, Christina (CELLS - ALBA, LLS) ; Nosych, Andriy (CELLS - ALBA, LLS) ; Potenza, Marco (INFN, Milan ; Milan U.) ; Roncarolo, Federico (CERN) ; Siano, Mirko (Milan U.) ; Trad, Georges (CERN)
We present the recent developments of a study aiming at measuring the transverse beam profile using the Heterodyne Near Field Speckles (HNFS) method. The HNFS technique consists of a suspension of nanoparticles suspended in a liquid and illuminated by synchrotron radiation (either in the visible or in X-ray wavelength range). [...]

Electron Beam Size Measurements Using the Heterodyne Near Field Speckles at ALBA
/ Siano, Mirko (Milan U.) ; Iriso, Ubaldo (CELLS - ALBA, LLS) ; Kamma-Lorger, Christina (CELLS - ALBA, LLS) ; Mazzoni, Stefano (CERN) ; Nosych, Andriy (CELLS - ALBA, LLS) ; Paroli, Bruno (Milan U.) ; Potenza, Marco (Milan U.) ; Trad, Georges (CERN)
Experiments using the heterodyne near field speckle method (HNFS) have been performed at ALBA to characterize the spatial coherence of the synchrotron radiation, with the ultimate goal of measuring both the horizontal and vertical electron beam sizes. The HNFS technique consists on the analysis of the interference between the radiation scattered by a colloidal suspension of nanoparticles and the synchrotron radiation, which in this case corresponds to the hard x-rays (12keV) produced by the in-vacuum undulator of the NCD-Sweet beamline. [...]

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. [...]

Transverse Beam Size Diagnostics using Brownian Nanoparticles at ALBA
/ Siano, Mirko (INFN, Milan ; Milan U.) ; Goldblatt, Aurelie N (CERN) ; Iriso, Ubaldo (CELLS - ALBA, LLS) ; Mazzoni, Stefano (CERN) ; Nosych, Andriy (CELLS - ALBA, LLS) ; Paroli, Bruno (INFN, Milan ; Milan U.) ; Potenza, Marco (INFN, Milan ; Milan U.) ; Torino, Laura (CELLS - ALBA, LLS) ; Trad, Georges (CERN)
In this work we describe a novel beam diagnostic method based on coherence characterization of broad-spectrum bending magnet radiation through the Heterodyne Near Field Scattering (HNFS) technique. HNFS is a self- referencing technique based on the interference between the transmitted beam and the spherical waves scattered by each particle of a colloidal suspension. [...]

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. [...]

FOCUS: Fast Monte-CarlO Approach to Coherence of Undulator Sources

We present Fast Monte-CarlO approach to Coherence of Undulator Sources (FOCUS), a new GPU-based code to compute the transverse coherence of X-ray radiation from undulator sources. The code relies on scaled dimension- less quantities and analytic expressions of the electric field emitted by electrons in an undulator. [...]

In this paper we extensively describe the heterodyne near field speckle method (HNFS) to characterize both spatial and temporal coherence of synchrotron radiation (SR). The method relies on Fourier analysis of near field speckles generated by scattering from nanoparticles suspended in a liquid. [...]

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. [...]

Optics Measurement using the N-BPM Method for the ALBA Synchrotron
/ Langner, Andy (CERN) ; Benedetti, Gabriele (CELLS - ALBA, LLS) ; Carlà, Michele (CELLS - ALBA, LLS) ; Coello de Portugal, Jaime Maria (CERN) ; Iriso, Ubaldo (CELLS - ALBA, LLS) ; Martí, Zeus (CELLS - ALBA, LLS) ; Tomás, Rogelio (CERN)
The N-BPM method recently developed for the LHC has significantly improved the precision of optics measurements which are based on beam position monitor (BPM) turn-by-turn data. The main improvement is owed to the consideration of correlations for statistical and systematic error sources, as well as increasing the amount of BPM combinations for one measurement. [...]
