Applied Physicist - Beam-Dust Interactions (TE-MPE-CB-2026-139-GRAP)

Job Description

Do you want to contribute to solving a long-standing mystery of particle accelerators: why can tiny dust grains have such a big impact on high energy particle beams? This could be the perfect opportunity for you.

You will lead the development of a novel experimental setup, from design and construction to commissioning, combining computational studies and hands-on testing to advance cutting-edge accelerator research.

Your responsibilities:

• Design and develop a dedicated test stand to study beam-dust interactions in accelerator environments.
• Conduct cutting-edge research in collaboration with experts in beam physics, machine protection, and vacuum technology.
• Develop and apply physics models for the charging and release mechanisms of macroscopic dust grains on conducting and insulating surfaces.
• Design and execute experimental tests to validate theoretical models.
• Investigate controlled methods for producing and reproducing beam-dust interaction events.
• Identify and propose mitigation strategies to minimise dust-induced beam losses in future accelerator facilities.

Your profile:

• Demonstrated experience in modelling physics phenomena.
• Experience in setting up and conducting laboratory experiments, including measurement analysis.
• Experience with numerical simulations and scientific computing would be an asset.

Skills:

• Solid understanding of particle accelerators and beam physics.
• Strong foundation in classical electrodynamics.
• Proficiency in scientific programming (e.g., Python, MATLAB, or similar).
• Ability to work independently while collaborating effectively with experts from different technical domains.
• Creative problem-solving skills with the ability to develop innovative solutions.
• 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 related field (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.
