Laurent C. Chapon is the Associate Laboratory Director for PSC and Director of the Advanced Photon Source.
Laurent Chapon was director of physical sciences at the Diamond Light Source in the United Kingdom where he led the scientific strategy in this division and oversaw five of Diamond’s eight science groups. He led groups dedicated to technological advancements in optics, metrology, and detector technology at the facility, and oversaw the Project Office, the User Office, and the Experiment Hall groups. In parallel, Chapon was director of the Diamond-II project, recently awarded preliminary funding, for which he has developed the upgrade strategy, the science case, and the business case.
Prior to his time at Diamond, Chapon was a senior fellow and group leader of crystallography at the Institut Laue-Langevin in Grenoble, France. He spent nearly a decade at the ISIS Neutron and Muon Source at Rutherford Appleton Laboratory in the United Kingdom, as both an instrument scientist and a group leader of the diffraction and engineering group.
Chapon received his Ph.D. in Materials Science from the Université Montpellier-II, in France. He conducted research on the fundamental and thermoelectric properties of skutterudites using neutron scattering, x-ray diffraction and absorption spectroscopy. He conducted postdoctoral research at Argonne in 2001 on molecule-based magnets and has since worked mainly on the structural and magnetic properties of complex transition metal oxides, including multiferroics, as well as probing the exotic states of matter stabilized in frustrated magnetic systems and chiral compounds. He is an expert in magnetic scattering with neutrons and x-rays, crystallography, and magnetic symmetry.
Chapon received a Prize of the Physical Crystallography Group from the British Crystallography Association in 2008 for his work on multiferroics and magnetic crystallography. He has served in many international review committees for large scale user facilities, most recently at the Canadian Light Source, the SNS Second Target Station Instrument Review Committee at Oak Ridge National Laboratory and is currently the chair of the Program Advisory Committee for the Institut Laue Langevin, France; and sa member of the XFEL Physical Science Hub at the Central Laser Facility, United Kingdom. He serves as an editorial board member for the journal npj Quantum Materials and has coauthored more than 140 scientific publications.
