A post-doctoral research position is open starting on Nov. 1st 2015, in the VUV beamline DESIRS group (L. Nahon, G. A. Garcia, N. de Oliveira) at Synchrotron SOLEIL, on a PEPICO/molecular beam machine.
The DESIRS beamline, covering the 5-40 eV range with very high resolution and variable polarization aims at studying gas phase VUV high resolution spectroscopy and polarization-dependent molecular and photoionization dynamics (see http://www.synchrotron-soleil.fr/Recherche/Bibliotheque/DocumentationScientifique/DESIRS).
On one branch of the beamline is connected a versatile molecular beam chamber, SAPHIRS, allowing to handle gaseous, liquid and solid samples as well as nanoparticles. It is equipped with a double imaging electron/ion coincidence i2PEPICO spectrometer (G. A. Garcia et al., Rev. Sci. Instrum. 84, 053112 (2013)), coupling a VMI spectrometer for the electrons with a 3D momentum imaging spectrometer on the ion side.
The candidate will be involved in one or more of the topics developed on this branch, for which he/she is expected to propose a sound personal contribution, including:
• VUV photodynamics (spectroscopy, fragmentation and photoionization) of size-selected molecular complexes and clusters via TPEPICO, AR-PEPICO and e-/ion energy correlations.
• Room Temperature chemical reactions of atmospheric interest probed by i2PEPICO.
• High resolution AR-PES to probe photoionization dynamics on small molecular systems including radicals.
• Photoelectron Circular Dichroism (PECD) on various chiral samples.
• Angle-resolved Photoemission on nanoparticles and chemical composition studies via aerosol thermodesorption.
Besides this in-house research program, the candidate will host external user teams on the SAPHIRS branch with whom we have established collaborations (on biomolecules, radicals, combustion processes, clusters...). He/she will also be involved in instrumental developments regarding the spectrometer itself as well as the sample environments.
The contract is for 1 year renewable once upon mutual agreement. Knowledge of French is not mandatory, but a fluent level of spoken and written English is required.
The candidate is expected to hold a PhD in Physical Chemistry or Physics, since no more than 3 years. A solid background in gas phase molecular dynamics and/or photoionization dynamics is necessary, as well as experience in electron and/or ion mass spectroscopy associated with molecular beams. Previous expertise in handling samples such as molecular complexes, clusters or nanoparticles would be a real plus. Experience in synchrotron radiation and/or coincidence techniques is not mandatory, but will be certainly considered.
Motivated candidates should contact by e-mail Laurent Nahon ([log in to unmask]) providing a cover/motivation letter, CV and list of publications before June 15th. By June 25th, selected candidates will be notified to arrange for providing two reference letters before July 10th. Interviews (via skype if needed) will be conducted before the end of July.
