Missions

The candidate will work together with the scientists and the engineers from the LP2iB laboratory (Laboratoire de Physique des deux Infinis de Bordeaux) and the GSI/FAIR facility in the preparation and the realization of our next experiment at the Experimental Storage Ring (ESR) of GSI/FAIR, as well as in the analysis and interpretation of the data measured in our last experiment. The candidate will contribute to designing, mounting and testing different detection systems for our new reaction chamber, ensuring their compatibility with the ultra-high vacuum conditions of the ESR. The candidate will present our work at international conferences and will coordinate the writing of scientific articles describing the experiments and the results. Finally, the candidate will participate to the supervision of PhD, master and undergraduate students.

Contexte de travail

This post-doctoral position is funded by the ERC-Advanced grant NECTAR (Nuclear rEaCTions At storage Rings, https://www.lp2ib.in2p3.fr/nucleaire/nex/erc-nectar/ ). The aim of NECTAR is to determine neutron-induced reaction cross sections of radioactive nuclei. These cross sections are essential to understand the synthesis of heavy elements in stars and for applications. However, the difficulties to produce and manipulate the necessary amounts of radioactive nuclei make the direct measurement of such cross sections extremely difficult or even impossible. Surrogate reactions in inverse kinematics represent one of the most promising indirect approaches to determine these cross sections. NECTAR combines for the first time surrogate reactions with the ESR storage ring of the GSI/FAIR facility in Germany, which offers the ideal conditions for the study of this type of reactions. The first two NECTAR experiments successfully conducted in 2022 and 2024 have shown the significant advantages of this combination (see https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.134.072501 and https://journals.aps.org/prc/abstract/10.1103/PhysRevC.111.024614).
The person recruited will work at the LP2iB, which is a mixed unit composed of staff from the Centre National de Recherche Scientifique (CNRS) and the University of Bordeaux. Frequent travel to GSI/FAIR in Darmstadt, Germany, is to be foreseen, with stays of several weeks to several months. The working hours are those of LP2iB and GSI, except in exceptional cases, for example during experiments.
