Fellowship at CERN: Collective Effects with Muons

Great opportunity to work under the supervision of the JUAS Director, Elias METRAL at CERN:

Applied Physicist – Collective Effects with Muons (BE-ABP-CEI-2025-38-GRAP)

As an Applied Physicist in this exciting field, you will:

• Analyse beam loading effects and their impact on the design of the ionisation cooling cell.
• Investigate collective instabilities that could limit beam quality during cooling and acceleration.
• Study the low-energy acceleration phase (0.2–60 GeV) in pre-accelerators and Recirculating Linear Accelerators (RLAs).
• Perform start-to-end simulations, connecting the cooling phase to beam collisions.
• Identify performance limitations arising from collective effects and propose mitigation strategies.
• Collaborate with international experts in the IMCC to advance muon collider technology.

Your profile

Skills

• Knowledge of Beam dynamics.
• Knowledge of collective effects.
• Knowledge of beam tracking in rings.
• Fluent in English, the ability to work in French would be an advantage.

Eligibility criteria:

• You are a national of a CERN Member or Associate Member State.
• You have a professional background in Accelerator physics, muon colliders (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.
