At CERN, the European Organisation for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world's largest and most complex scientific instruments, they study the basic constituents of matter - fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact, and provides insights into the fundamental laws of nature.

Job description
The n_TOF facility at CERN provides high-intensity, wide-energy neutron beams for high-precision studies in nuclear astrophysics and medical applications. This position will focus on simulation studies with the aim of optimising the facilities performance.
You will contribute to neutronics validation and benchmarking of the latest neutron data libraries. The work will include the redesign of a collimation system as well as the design of a dedicated neutron transmission measurement station.
You will also have the opportunity to gain experience in the operations experimental facilities as part of the local support team for n_TOF.
Your 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.
Your profile
Experience in using Monte Carlo transport codes for physics experiments.
Experience performing studies in the field of neutron physics/neutronics.
Skills:
Neutron physics knowledge.
Monte Carlo simulation.
Fluka knowledge would be an advantage.
Spoken and written English, with a commitment to learn French.
Eligibility criteria:
You are a national of a CERN Member or Associate Member State.
You have a professional background in Physics (or a related field) and have either:
a Master's degree with 2 to 6 years of post-graduation professional experience;
or a PhD with no more than 3 years of post-graduation professional experience.
You have never had a CERN fellow or graduate contract before.
This position involves:
Work in Radiation Areas.
Interventions in underground installations.
Stand-by duty, when required by the needs of the Organisation.
Work during nights, Sundays and official holidays, when required by the needs of the Organisation.
What we offer
A monthly stipend ranging between 6,372-7,004 Swiss Francs (net of tax).
Coverage by CERN's comprehensive health scheme (for yourself, your spouse and children), and membership of the CERN Pension Fund.
Depending on your individual circumstances: installation grant; family, child and infant allowances; payment of travel expenses at the beginning and end of contract.
30 days of paid leave per year.
On-the-job and formal training at CERN as well as in-house language courses for English and/or French.
We've signed the Gradcracker feedback pledge.
(This means that we will supply feedback if requested after an interview.)
