For the accelerator-based future of high energy physics at the energy frontier, CERN started to investigate a 92 km circumference Future Circular Collider (FCC), as e⁺/e⁻ collider the FCC-ee will operate at beam energies up to 182.5 GeV. Beside the machine operational aspects, beam instrumentation will play a key role in verifying and optimizing the machine to achieve the ambitious beam parameters and quality. [...]

Milan (main)) ; Potenza, Marco (U. Milan (main)) ; Torino, Laura (CELLS - ALBA, LLS) et al.
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. [...]

ALBA is currently equipped with two X-ray pinhole cameras for continuous beam size monitoring using the synchrotron radiation from two different bending magnets. The first pinhole was installed on day-1 and it is working properly since 2011 as the work-horse for the ALBA emittance measurements. [...]

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. [...]

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. [...]

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.
