Applied Physicist - CLEAR Facility (BE-ABP-PEC-2025-216-GRAP)

You will contribute to the operation and development of the CLEAR user facility, optimising beam parameters to meet experimental needs. The role includes coordinating with user groups, supporting experiments, and following up on requests. A key focus is on medical research, including Very High Energy Electrons (VHEE) and FLASH radiotherapy. You will coordinate beam-time activities, improve operational tools and procedures, and take part in consolidation and upgrade projects. The role also involves mentoring students and leading training activities at CLEAR and partner schools such as JUAS and ATSOA.

Your responsibilities:

• Operate a linear electron accelerator;
• Communicate and provide support to user groups;
• Carry out beam experiments aimed at the development of novel cancer radiotherapy techniques;
• Collaborate on the development and improvement of software tools for accelerator operation;
• Train and supervise undergraduate and graduate students;
• This role includes team supervision responsibilities.

Your profile:

Experience:

• Experience in particle accelerator operation, especially on electron beams;
• Knowledge of accelerator physics;
• Familiarity with software development and programming;
• Experience and/or knowledge of medical applications of particle beams is a plus.

Skills:

• Analysis and optimisation of accelerator performance;
• Operation of accelerators;
• Operation and support of experimental facilities;
• Assembly and integration of experiments;
• Knowledge and application of accelerator physics theory;
• Applied medical physics;
• Spoken and written English or French, with a commitment to learn the other language.

Eligibility criteria:

• You are a national of a CERN Member or Associate Member State.
• You have a professional background in Applied physicist or Engineering (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.
