Vincent Thominet has been working at the Paul Scherrer Institut as an optics engineer since 2008.
Before joining PSI, he worked as engineer in the optics groups of two industrial companies:
Sodern, a subsidiary of the Ariane-Group near Paris and a Bosch applied research center near Lausanne.
Vincent Thominet studied optics at the Institut d'optique Graduate School affiliated to the University of Paris-Saclay.

Vincent Thominet's main subjects are visible optics design and metrology for quality assurance. Examples are the design of alignment lasers, beam diagnostics, sample camera systems and microscopes for SLS (Booster, PX, cSAXS, NanoXAS, SIM, X-Treme),  SLS2, SINQ (Neutron Radiography, OPTIS) and SwissFEL (ACHIP, Aramis & Athos endstations).

Mirror systems for SwissFEL, from concept to commissioning with x-rays
Flechsig, U. & Spielmann, S & Thominet, V & Follath, R & Krempasky, J & Wagner, U & Patthey, L. (2019).
AIP Conference Proceedings. 2054. 060001. 10.1063/1.5084632.
The two Aramis beamlines at SwissFEL are currently under commissioning, first pilot experiments have already been carried out. In total we have 10 mirror systems, 6 offset mirrors and 4 mirrors in KB [1] configuration. The performance of the mirror systems has been verified with X-rays.

The SwissFEL Aramis beamline, covering the photon energies between 1.77 keV and 12.7 keV, features a suite of online photon diagnostics tools to help both users and FEL operators in analysing data and optimizing experimental and beamline performance. This manuscript is an overview of the diagnostics tools available at SwissFEL and presents their design, working principles and capabilities.

(2014). Journal of synchrotron radiation. 21. 340-51. 10.1107/S160057751400006X.
A new diffractometer for microcrystallography has been developed for the three macromolecular crystallography beamlines of the Swiss Light Source. It integrates the on-axis microspectrophotometer MS3 for microscopic sample imaging with 1 μm image resolution. Its multi-mode optical spectroscopy module is always online and supports in situ UV/Vis absorption, fluorescence and Raman spectroscopy.
