The Department of Physics at Technische Universität Darmstadt, Institute of Nuclear Physics, group of Professor Dr. Alexandre Obertelli, is searching a

Research Associate/Postdoc (all genders)

The contract duration will be limited until 31.12.2023. The position is embedded in the Collaborative Research Center 1245 funded by the German Research Foundation (DFG). In case of a successful approval of a further funding period, an extension of the term of employment is foreseen.

The Collaborative Research Center 1245 "Atomic Nuclei: From Fundamental Interactions to Structure and Stars" together with the Johannes Gutenberg University Mainz aims at the study of strong and electroweak interactions as they occur in atomic nuclei as well as in stars.

The position holder is expected to perform research tasks in the framework of subproject A8 "Evolution of the shell structure on the way to the neutron break-off edge". Within this subproject a detector system (Silicon Tracker for RAdioactive-nuclei Studies at SAMURAI Experiments, STRASSE) will be developed and built to perform missing-mass and gamma spectroscopy in quasi-free (p,2p) scattering experiments in inverse kinematics. SAMURAI is part of the RIBF accelerator facility in Wako, Japan. The goal here is to study atomic nuclei with very large neutron-to-proton asymmetry. STRASSE will consist of a highly segmented silicon strip detector, which will be combined with a reaction volume of liquid hydrogen. In addition, STRASSE will be operated in combination with particle calorimeters and gamma detectors.

The position holder is expected to play a leading role in the further construction, testing and commissioning of the detector system and in particular also to develop the liquid hydrogen target and integrate it into STRASSE. In addition, she_he is expected to provide significant support to the experimental program in Japan and to the analysis and interpretation of the data obtained in the SAMURAI-069 experimental program. Preparation for publication of results in peer-reviewed journals and their presentation at conferences and workshops is required, as well as involvement in other SFB activities.

A completed PhD in the field of physics at a scientific university, knowledge and experience in the field of nuclear structure physics, in-depth knowledge in the development and operation of suitable detector systems for experiments in basic nuclear physics research with particle beams, experience in the analysis of such experiments, and a strong reliability and commitment are expected. Experience in working with liquid hydrogen and in supervising students is an advantage.

The fulfillment of the duties likewise enables the scientific qualifications of the candidate.

The Technische Universität Darmstadt intends to increase the number of female employees and encourages female candidates to apply. In case of equal qualifications applicants with a degree of disability of at least 50 or equal will be given preference. Wages and salaries are according to the collective agreements on salary scales, which apply to the Technische Universität Darmstadt (TV-TU Darmstadt). Part-time employment is generally possible.

Applications (in English) with curriculum vitae, letter of motivation, as well as final certificates should be sent in electronic form (as one pdf file), quoting the identification number, to the Managing Director of the Institute of Nuclear Physics, Professor Dr. Dr. hc. mult. Norbert Pietralla (
