The postdoctoral researcher is expected to be involved in the successful installation and running of the nu-Ball2 gamma-ray spectrometer and its associated experimental program in 2022 and 2023. The nu-Ball2 project concerns the construction and deployment of a high efficiency hybrid Ge/LaBr3 detector for experimental nuclear studies at the ALTO facility of IJC Lab Orsay and is coordinated by Dr. Jon Wilson and Dr. Gabriel Charles. The successful candidate will be expected to be part of the team which helps run nu-Ball2 experiments at the ALTO within the context of an international collaboration. They will be involved in the analysis of data from one or more of these experiments which are related in particular to the spectroscopy of nuclear fission and nuclear structure studies. along with creativity, implementation of original ideas and the ability to work highly effectively within a small dedicated team.


The post-doctoral researcher will contribute to activities such as detector monitoring and fault detection, data processing and optimisation, data analysis and publication of one or more individual and/or joint articles based on results obtained during the project.


Practical experience with radiation detectors, particularly gamma-ray detectors is essential. Familiarity with sensitive Germanium detectors would be a distinct advantage. A knowledge of modern programming languages and analysis tools, e.g. C++, root and simulation tools such as GEANT IV is highly desirable. Knowledge of digital signal processing techniques and optimisation would be an advantage. The successful candidate should speak good English. French language skills would be an advantage, but not essential. An aptitude for working collaboratively in a dedicated team in the context of an international project/facility is required. The ability to work independently in a well-organised fashion on activities related to data analysis, etc. is also important.
Candidates must hold a doctorate in a related field and have proven research skills evidenced by a least one publication as the first/joint first or second author relating to the subject or activities of the project.

Work Context

The postdoctoral researcher will be part of the Structure Decay and Fission (SDF) group of the nuclear pole of IJC Lab, Orsay. The group includes around 15 physicists (permanent researchers, post-docs and doctoral students). The nu-Ball2 project on which they will work will be carried out at the ALTO facility of IJC Lab.
The ALTO facility is a platform hosting two accelerators that performs experiments in nuclear physics, astrophysics and interdisciplinary research.
Irène Joliot-Curie Physics Laboratory of 2 Infinities (IJCLab) is a mixed research/teaching laboratory 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 campus is located 20 km south of Paris and easily accessible by RER in 35 minutes.
IJCLab was born in 2020 from the merger of five units (CSNSM, IMNC, IPN, LAL, LPT). There are around 560 permanent staff members and approximately 200 non-permanent including 120 doctoral students. The research themes of the laboratory are nuclear physics, high energy physics, theoretical physics, astroparticles, astrophysics and cosmology, particle accelerators, energy and the environment and health.

Additional Information

Please submit a cover letter and CV without any breaks in dates, showing diplomas, titles and work and professional experience along with two letters of recommendation.
The closing date for the receipt of applications is 10/02/2022.
As IJCLab is subjected to ZRR (Zone à Régime Restrictif) military regulation, hiring choices must be approved by the Haut Fonctionnaire Securité Défense (HFSD). Therefore, the date of employment written above should be understood as provisional, and may need to be delayed.
