What you'll do
In this role, you will perform Monte Carlo radiation transport studies for the FCC-ee technical insertions, quantifying the radiation exposure of equipment installed in the FCC-ee tunnel. In addition, you will perform energy deposition studies for the design of different FCC-ee accelerator systems, in particular the collider and booster dump systems and protection devices.
Your responsibilities
Carry out particle-matter interaction studies with the FLUKA Monte Carlo code and implement geometry models for FCC-ee machine studies.
Assess the expected radiation levels due to regular beam losses and synchrotron radiation emission in the FCC-ee technical insertions.
Perform energy deposition studies for accidental beam losses in FCC-ee and actively participate in the conceptual design of FCC-ee protection devices (absorbers, collimators) and dumps.
Closely collaborate with beam physicists and mechanical engineers, in order to translate absorber and dump concepts into technical specifications
Your profile
Knowledge of particle-matter interactions;
Experience with Monte Carlo radiation transport simulations and transport codes (FLUKA, Geant4, etc.);
Proficiency in scientific computing;
Knowledge of accelerator physics is an advantage
Your skills
Basic programming skills (e.g. Python, C++) for data analysis and code development;
Familiarity with numerical methods and scientific computing;
Problem-solving mindset and ability to learn new tools quickly (e.g. auxiliary tools for particle transport simulations);
Excellent team-working attitude, with colleagues from different fields of applied physics and engineering (multidisciplinary and international environment)
Ideal start date: 01/03/2026
Contract duration: 24 month contract
Job flexibility: Fully Onsite
