A post-doctoral researcher position is presently available to join a collaborative program between two research groups at the Institut des Sciences Moléculaires d’Orsay and the SOLEIL Synchrotron light source , dedicated to ultrafast dynamics of electronic and nuclear wavepackets in isolated molecules, from valence- and inner-shell photoionization to fragmentation and reaction dynamics, in time-resolved studies at the attosecond (as) and femtosecond (fs) time scales.

This program will take place in the context of the development of the ATTOLab facility which includes two high performance laser systems (Ti:sapphire IR, <20fs, CEP phase stabilized, respectively 15W/1kHz and 20W/10kHz, installed at CEA/l’Orme-les-Merisiers), and associated attosecond sources in the extreme-UV (XUV) based on laser-driven high harmonic generation. Advanced optical instrumentation of the XUV beamlines is being developed in the related OPT2X project with support of the Université Paris-Saclay.

The experiments will make use of multiparticle coincidence spectroscopy techniques to access physical observables at the most sensitive level, in particular through time-resolved studies of molecular-frame photoemission in excited molecules undergoing ultrafast dynamical changes. The postdoc will contribute to further develop existing equipment, e.g., electron/ion momentum imaging spectrometer of COLTRIMS type, and adapt it to the new capabilities of the 10 kHz attosecond beamline in ATTOLab. In parallel, photoemission studies will be carried out on the PLEIADES beamline at SOLEIL synchrotron. Within the synergy provided by the Université Paris-Saclay groups, opportunities will exist for the post-doctorate fellow to test new ideas using harmonic sources, synchrotron radiation and possibly FEL sources. Close collaborations with theoretical groups have already been established and will be essential to the interpretation of the data.

The candidate should have a PhD degree in either physics or physical chemistry granted within the last four years, and experience with some of the following topics:

– Gas phase molecular & photoionization dynamics using XUV radiation sources
– Multiparticle coincidence spectroscopy & data analysis
– Time & position sensitive charged particle detection

The position is currently available for one year with the possibility of one year extension on mutual agreement. Motivated candidates should forward a CV and contact information for two references before July 10th to:
