Engineer in physics, specialised in optics. Experience: R&D geometry and optics, colloids, soft matter
Working experience 19992004 19992001 : research engineer at CNRS (Centre National de la recherche scientifique, France). Research in the field of light propagation in complex media. Experiments have been settled for the study of coherent light diffusion. The purpose is to extract information about the diffusing media for instance fluid hydrodynamic properties (particles Brownian motion, circulation, diffusion, convection) Design of the experimental setup, the software: Monte Carlo for the simulation of propagation of photons in diffusive media and optical interfaces, signal processing connected to physics models in order to extract the desired physical parameter. 20012007 Company Formulaction . R&D. In collaboration with the marketing team, design of new instruments of complex media analysis used in research labs of the fields: chemical, food, cosmetics, oil, ...
Working experience 19941999 199499: participation to the CMS (Compact Muon Solenoid) project, experiment for the future hadron collider (LHC) at CERN. Design of a monitor allowing the measurement of the spatial co ordinates of the muon chambers. Context: large size project involving 1600 physicists and engineers from various institutes and universities all over the world. The first collision detected by CMS is foreseen in 2007. Feasibility study of an optical system for the measurement of the position of 250 muon chambers. The system must measure the 3D coordinates of 1000 points inside a volume of typical size 14m with a precision of 100 to 200 microns. There are high constraints for the space available. Engineering of a project started with the survey and geometry group at CERN. Link between this group and physicists. August 1994: proposal (CMS TN 94239 August 1994) for the position monitor for the muon chambers based on the used of video cameras mounted on a very stable calibrated mechanical structure (concept called MAB: "Module for the alignment of the barrel"). The "barrel" is a part of the CMS experiment. The proposal has been inserted in the global technical proposal of CMS addresses to the referees of the LHC comity (CMS LHCC 9438, 1994). September 1994: Integration of the proposed system inside the CMS experiment by collaboration with the integration group of CMS. Study and realisation of a laboratory for testing prototypes using video cameras. Closed collaboration with the survey group of CERN to understand the evaluation methods of the error propagation. ("Muon barrel alignment: third report" January 1995). 1995: integration, study of prototypes in laboratory and detailed study of the possibility of an opto mechanical module extremely stable (30 microns) having a dimensions of 4m by 1m. This module is the base of the position monitor. Daily collaboration with 2 engineers specialised in finite element calculation in order to define the best performance satisfying the constraints of price, integration and the requirements of optics and geometry (dimensional stability). February 1996: Work with a team designing an optical system connected to the previously described position monitor: the link system between the central particle detectors and the (external) muon detectors. The device is based on using lasers and optical levels in order to transport the
geometry from the central detector towards the muon detectors. 19961999: final design of the position monitor of the muon detectors (optics, mechanics, software prototype). Design of a MAB prototype. Design of large laboratory for the final validation of the full position monitor. Writing of a general software (called Simulgeo, object oriented, java) allowing the design, simulation and treatment of hardware signals of any optogeometrical system using video cameras, lasers, optical sources, etc... This software permits a precise evaluation of the measurement precision by integrating some techniques used in geodesy. It is now used also by the group LiCAS (Linear Collider Alignment and Survey, University of Oxford). Writing of the requirement document for the market survey for the MAB mechanical modules.
Working experience 19921994 Within the group SLBI (SPSLEP, group Beam Instrumentation of the LEP electronpositron collider). Improvement (optics, mechanics, electronics) and theoretical studies of telescopes observing the synchrotron radiation of the LEP lepton beam. These telescopes image a transverse cut of the lepton beam and allow measurement of the beam emittance (size). Simulation of diffraction phenomena present in the telescope for correction. Study of the thermal noise of the CCD sensor. Study of the electronics chain of image acquisition. Measurement on specific beams of the LEP for the calibration of the instrument and to understand better the synchrotron radiation emission. Series of courses on fundamental optics given to the group SLBIPM.
