	LUCIA is a micro-focused beamline (0.8 - 8 keV) dedicated to X-ray fluorescence and X-ray absorption spectroscopy at SOLEIL Synchrotron.* With its recent optical upgrade and photons flux increase, the three pink-beam diagnostics of the beamline have been upgraded to support a beam reaching 10¹³ph/s and 20 W/mm².

LUCIA is a micro-focused beamline (0.8 - 8 keV) dedicated to X-ray fluorescence and X-ray absorption spectroscopy at SOLEIL Synchrotron.* With its recent optical upgrade and photons flux increase, the three pink-beam diagnostics of the beamline have been upgraded to support a beam reaching 10¹³ph/s and 20 W/mm². This paper presents the thermomechanical study and the realization of new devices adapted to the current constraints of use, making possible to both visualize the shape of the pink beam and to measure its intensity simultaneously in the same compact device. The beam is visualized by a piece of Al2O3 - Cr ceramic, soldered to a copper heat sink, whose fluorescence image is visible in visible light with a suitable camera and optical system. The measurement of the photonic intensity is made by a polarized CVD diamond used as a photosensitive element, the current reading is made by a suitable low current amplifier. The design of this dual beam visualizer and intensity monitor, made by the SOLEIL detectors group with thermomechanical studies done by the Mechanical Design Office, will be presented in details. In-lab measurements will be also presented.
