Prof.) Project description: Radiation is implicated in a large number of Research fields among which astrochemistry (e.g., production of complex molecules in interstellar icy grain), nanolithography or radiation biology. Although it is usually observed that the nature of the irradiated medium is modified, the mechanism by which it operates, is nevertheless far being fully understood. Irradiation of mass selected molecular nanosystems is a nes field of research open to technical innovation as well as theoretical developments. At IPNL, a new experimental apparatus, DIAM (Dispositif d’Irradiation d’Agrégats Moléculaires) has been developed by the IPM group (interaction Particule Matière) to explore the intrinsic processes arising from the interaction of 20-­‐150 keV protons with nano-­‐systems, mass-­‐selected by a ExB spectrometer prior to the interaction. The produced fragments (ion and neutral species) are detected by a Time-­‐of-­‐Flight technique coupled to fast acquisition electronics and analyzed under ROOT® environment. This detection setup allows a correlation analysis of species produced within an event, in a set of events. The successful candidate will strongly participate in the implementation of the proton beam (characterization, test, …) in the existing collision chamber. Then, he will be involved in proton-­‐molecule collision experiments. According to her/his possibility, the work could point towards developments of methods in Analytical Sciences, statistical physics of system of finite size or dynamics of nano-­‐systems under strong non-­‐linear perturbations. Enquiries and/or applications consisting of a resume, a brief statement of research interests, and the names and addresses of at least three references (3-­‐page limit), should be submitted to Dr. B. Farizon (see above)
