Postdoctoral position PUMA beamline

Gif sur Yvette

Job description:

SOLEIL is the French national synchrotron facility, located on the Saclay Plateau near Paris. It is a multi-disciplinary instrument and research laboratory whose mission is to conduct research using synchrotron radiation, to develop cutting edge instrumentation on the beamlines, and to make these developments available to the scientific community. SOLEIL synchrotron, a unique tool for both academic research and industrial applications across a wide range of disciplines including physics, biology, chemistry etc., opened in 2008. It is used annually by thousands researchers from France and abroad. SOLEIL is based on a synchrotron source that is state-of-the-art both in terms of brilliance and stability. This large scale facility, a partner of the Université Paris Saclay, is a “publically owned” private company, founded by the CNRS and the CEA.

PUMA (French for « Photons Utilisés pour les Matériaux Anciens ») is a hard X-ray imaging beamline optimized for the scientific communities of the hertitage sciences. The 2d imaging endstation offers a resolution of several microns with elemental (XRF), chemical (XANES) and structural (XANES and XRD) contrast.

This opening will be situated in the Experiments Division at the PUMA beamline.

Detailed mission:


The candidate will be working in the experiments division at the PUMA beamline, whose team currently includes one scientist and one assistant engineer. The candidate will have the following missions:

To contribute to the user support program of the PUMA beamline ;

To participate in the commissioning and development of the instrumentation ;

To appropriate a research project in the heritage sciences in discussion with the beamline responsible ;

To prepare and perform the experiments necessary for the advancement of his scientific project ;

To analyse the data obtained from his research and publish his results in scientific journals ;

To present his results and the PUMA beamline in national and international conferences.
