Researcher in Scientific Instrumentation (M/F). Development of APT for cosmochemistry

Context:

This post doc is part of a wider project COSMO-SAT (P.I. A.-M. Seydoux-Guillaume, Co-P.I. F. Vurpillot and M. Roskosz) from the PEPR Origins (https://www.cnrs.fr/fr/cnrsinfo/pepr-origins-entre-ruptures-technologiques-et-origines-de-la-vie). The objective of COSMO-SAT is to develop a new generation of tomographic atom probe dedicated to the analysis of geological and extraterrestrial samples in order to significantly improve their quantitative and isotopic measurements at the nanometric scale. Measuring quantitatively the elemental and isotopic composition of samples, down to the atomic scale, allows to trace and quantify the irradiation processes and the gas-grain interactions in the protoplanetary disk, to determine the origin of presolar grains and their associated nucleosynthesis, as well as the origin of primitive complex objects. The project has several

ambitious instrumental improvement objectives (https://pepr-origins.fr/projet/cosmo-sat-2/) to tackle various questions. This will be at the centre of the present Post doc. More details in the attached pdf

Profile:

The targeted candidate should hold a PhD in materials science characterization. Moreover, knowledge in data mining on atomic scale analytical techniques are pre-requisites for the successful completion of this project. Prior experience on FIB preparation, APT or TEM would be an advantage.
