Missions

The objective of the COSMOSAT project is to develop a new generation of Atom Probe, instrument non-existent at present. This instrument will be unique on a worldewide scale and will be optimized and dedicated to the analysis of cosmochemical samples thanks to the partnership between the GPM of Rouen, the only university French laboratory to develop its own instruments, and CAMECA, the only (French) company to market this type of instrument. The researcher will have in charge the optimization of the prototype under development.

The researcher will have in charge the optimization of the prototype under development with tasks concerning
➢ UHV Chamber optimization
➢ Test of the new energy compensation device of the Atom probe (hardware and software optimisation)
➢ Tests and optimisation of the laser pulsing capabilities
➢ Tests and optimisation of the detection system (hardware and software optimisation)
➢ Experimental analyses on geological materials (performance evaluation)

Activities

• Hardware design of the prototype (proposing possible modifications of the prototype)
• Hardware tests of different subparts (detectors / laser pulsing units / focusing units / UHV pumping
Software optimisation of the prototype and acquisition system
• Experimental analysis on the instrument
Tests and evaluations and optimisation of performances of the instrument
• Scientific production (articles and communications in scientific congress…)

Work Context

The GPM (“Groupe de Physique des Matériaux”, UMR CNRS 6634) is structured into 5 departments: Materials-Aging-Mechanics, Scientific Instrumentation, Nanosciences, Disordered Systems-Polymers and Nano-Health-Physics. It brings together 140 staff, including 60 Professors/Researchers, 30 ITAs and 50 PhD students/Postdocs/Trainees. The laboratory is located on the Campus Sciences et Ingénierie Rouen Normandie (in Rouen), within the University of Rouen Normandie and INSA Rouen Normandie (7000m2).
The recruited researcher (M/F) will be attached to the Scientific Instrumentation Department of the GPM, whose core business is the development of the Tomographic Atomic Probe, an instrument for nanoanalysis of materials, whose manager is François Vurpillot, (N+1 of the recruited researcher). The researcher will be integrated into the COSMOSAT project development team (F. Vurpillot, G. Da Costa, J. Houard, F. Danoix)

The Scientific Instrumentation Department is recognized as an international leader in the development of materials nano-analysis instruments, among them the Atom Probe Tomography (APT) technique (unique lab to develop this technic in France). The department is composed of 8 prof/researchers, and trains approximately 3 new doctoral students per year who become nationally and internationally recognized specialists in this rapidly developing field. For 25 years, the department has been promoting these advances through collaboration with CAMECA, an industrial leader in the field of APT. The CNRS manages the patents and licensing contracts resulting from this research. Note that the scientific instrumentation in support of an integrated technical staff of 6 engineers and assistant engineers.
Scientific instrumentation is a sub-discipline in Materials Science (a sub-theme of the 28th section of the CNU, or section 5 of the CNRS) but which requires extremely broad skills in the fields of physics (Materials, Cryogenics , optics, atomic physics, etc.), electronics, and data sciences. This research activity was born with the laboratory more than fifty years ago, and has been pursued continuously with unusual success by several generations of researchers and engineers who have passed on the relay of scientific excellence.

The position is located in a sector under the protection of scientific and technical potential (PPST), and therefore requires, in accordance with the regulations, that your arrival is authorized by the competent authority of the MESR.
