Missions

The position is open to motivated young researchers who wish to develop their skills in low-energy experimental nuclear physics. IJCLab is involved in several technical developments for the new SPIRAL2 facility at GANIL, such as S3-LEB, NEWGAIN, and DESIR. As part of this position, the selected candidate will join the ongoing efforts to develop ion traps for the DESIR facility. More specifically, the work will focus on the construction of an EBIT (Electron Beam Ion Trap) for the ANR HINA project, which aims to study nuclear decay in highly charged ions produced at the DESIR installation.

Activités

The postdoctoral researcher will be responsible for developing the highly charged ion (HCI) production system. This will include the design, construction, and testing of the experimental setup at the Max Planck Institute, followed by its commioning at IJCLab on the MOSAIC platform. The young researcher will also have the opportunity to contribute to the development of the HCI physics program at the DESIR facility. Additionally, he/she will be responsible for supervising Master's and PhD students.

Compétences

The fellow must hold a doctoral degree in nuclear physics. Priority will be given to candidates with skills related to experimental nuclear physics at low-energy. Experience with charge breeding (EBIS/EBIT) would be an asset.
Expertise in the following areas is desirable:
• Mass spectrometry and related techniques (Ion trapping and cooling, ion optics simulation (SIMION, COMSOL Multiphysics), ion detection at low energy, high vacuum technology, etc.);
• Related electronics;
• Data processing and analysis (ROOT, Python, etc.);
• Scientific and Technical Writing.
Soft skills:
• Team work;
• Ability to supervise students (PhD and Master);
• Ability to adapt to new environments.

Contexte de travail

The Irène Joliot-Curie Physics Laboratory of 2 Infinities (IJCLab) is a UMR under the supervision of the CNRS (IN2P3), the University of Paris-Saclay and the University of Paris is located on the campus of the University of Paris -Saclay in Orsay. The laboratory is located on the campus of the Université Paris-Sud, Université Paris-Saclay in Orsay. The campus is located 20 km south of Paris and easily accessible by RER in 35 minutes.
The research themes of the laboratory are nuclear physics, high energy physics, astroparticles and cosmology, theoretical physics, particle accelerators and detectors as well as technical research and development and associated applications for energy, health and the environment.
The successful postdoctoral fellow will join the FIIRST team in the nuclear physics department. In addition, the fellow will join the local trap team and a larger international collaboration, which groups top laboratories in trapping techniques in France (LP2I, LPC Caen, IJClab) and Germany (MPIK, University of Heidelberg).

Le poste se situe dans un secteur relevant de la protection du potentiel scientifique et technique (PPST), et nécessite donc, conformément à la réglementation, que votre arrivée soit autorisée par l'autorité compétente du MESR.

Contraintes et risques

Part of the work will be carried out at the Tancrède facility (MOSAIC) on the Orsay campus as well as at the Max Planck Institute (MPIK), where the selected candidate will be required to undertake long-term stays. The position is therefore subject to special working conditions related to potential exposure to ionizing radiation. The candidate must be authorized to work in a monitored and controlled area while complying with all nuclear safety and security rules and procedures.

Informations complémentaires

To apply, candidates must submit their application via the CNRS portal before November 21st 2025, including a curriculum vitae, a summary of their research experience, and the contact information of at least two research contacts. For any additional inquiries, please direct them to the CNRS portal.
