Postdoctoral position / 24-month fixed-term contract at Irfu,CEA Saclay, France

A postdoctoral position / 24-month fixed-term contract is open at Irfu, CEA-Saclay to work on the project SENTINELLE, with a focus on the development of a Micromegas detector for online monitoring of the reactivity of low-power nuclear systems.

The position is expected to start from November 2026 and no later than early April 2027.
Applications will be reviewed as they are received. As the CEA recruitment procedure takes approximately two months, interested candidates are encouraged to contact us sufficiently in advance of their preferred starting date.

The SENTINELLE project (Stochastic neutron noise techniques for online surveillance) aims to develop new methods for online monitoring of the reactivity of low-power nuclear systems using temporal fluctuations in the neutron signal – stochastic neutron noise. These fluctuations and the temporal correlations between neutron events contain information on fission chains and can therefore be used to infer parameters related to the multiplication of the nuclear system. The long-term objective is to demonstrate the feasibility of an integrated "detector + algorithm" system capable of estimating reactivity from neutron-noise measurements, for example during reactor start-up or for monitoring corium during decommissioning operations at the Fukushima Daiichi nuclear power plant.

Postdoctoral researcher position in precision beta decay at LLNL

The Nuclear Physics and Accelerator Technology Group at Lawrence Livermore National Laboratory is looking to hire a postdoctoral researcher to play a major role in performing precision nuclear beta-decay experiments using ion traps. The primary focus of this position will be on advancing the St. Benedict ion-trap program, which aims to measure beta-recoil-ion coincidences in superallowed mixed-mirror decays to test the unitarity of the CKM matrix. Responsibilities will include commissioning the detector system, helping collect the first experimental data with beams at the University of Notre Dame, and developing detailed simulations of the ion-trap dynamics, decay physics, particle propagation, and detector response. The collected data will then be used to validate the simulations, interpret the results, and quantify key experimental systematics. The candidate is also expected to contribute to the BPT and BEARtrap experimental programs that use ATLAS beams at ANL to study tensor currents in the electroweak interaction and beta-delayed neutron decay, respectively.

For more details and to apply for this position, please see the posting on the LLNL careers page https://www.llnl.gov/join-our-team/careers/find-your-job/all/REF8801O. Applications submitted on or before October 9th will receive full consideration.

For questions regarding this position, please contact Dr. Aaron Gallant (gallant3@llnl.gov) and Dr. Nicholas Scielzo (scielzo1@llnl.gov).
