Radiation Physicist FCC-ee; SY-STI-BMI--GRAP

Radiation Physicist for FCC-ee (SY-STI-BMI--GRAP)

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.

• 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.

• Knowledge of particle‑matter interactions.
• Experience with Monte Carlo radiation transport simulations.
• Proficiency in scientific computing.
• Knowledge of accelerator physics is an advantage.
• The ability to collaborate in a multidisciplinary and international team environment.

• Knowledge of Monte Carlo radiation transport codes (FLUKA, Geant4, etc.).
• 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.
• Spoken and written English, with a commitment to learn French.
• You have a professional background in Applied 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.

• Contract duration: 24 months, with a possible extension up to 36 months maximum.
• Working hours:
  
  40 hours per week.
• Job flexibility:
  Fully Onsite.
• Job reference: SY-STI-BMI--GRAP.
• Field of work:
  Applied Physics.
• A monthly stipend between 6,287 and 6,911 Swiss Francs per month (tax free) depending on your degree.
• 30 days of paid leave per year plus 2 weeks annual closure.
• Coverage by CERN’s comprehensive health insurance scheme (for yourself, your spouse and children), and membership of the CERN Pension Fund.
• Family, child and infant monthly allowances depending on your individual circumstances.
• A relocation package (installation grant and travel expenses) depending on your individual circumstances.
• Possibility to extend your contract up to 36 months.
• On-the-job and formal training including language classes.
