Applied Physicist - n_TOF Facility

The position focuses on simulation studies to optimize the n_TOF facility's performance, including neutronics validation and benchmarking of neutron data libraries. The role involves redesigning a collimation system and designing a neutron transmission measurement station, with opportunities to support experimental facility operations.

Responsibilities

• Simulation studies for n_TOF facility physics performance optimisation and future program.
• Redesign of a collimation system as well as the design of a dedicated neutron transmission measurement station.
• Quantifying and mitigating secondary radiation through optimised shielding configurations and design modifications.
• Use of FLUKA for advanced Monte Carlo modelling, including refinement of low-energy neutron transport, such as self-shielding effects in the unresolved resonance region and Doppler broadening corrections.
• Neutronics validation and benchmarking of the latest neutron data libraries.

Requirements

• You are a national of a CERN Member State or Associate Member State, excluding Pakistani and Lithuanian nationals for 2026 start date.
• By the application deadline, you have a master’s degree with 2 to 6 years of professional experience since graduation or a PhD with a maximum of 3 years of professional experience since graduation.
• You are not eligible with only a bachelor’s degree.
• You have never had a CERN fellow or graduate contract before.
• Experience in using Monte Carlo transport codes for physics experiments.
• Experience performing studies in the field of neutron physics / neutronics.
• Your studies focused on Physics.
• Neutron physics knowledge.
• Monte Carlo simulation.
• Fluka knowledge would be an advantage.
• Spoken and written English, with a commitment to learn French.
