The Radio Frequency Group (RF) within CERN's Accelerator Systems Department (SY) is seeking an Applied Physicist/Engineer to join the Superconducting Radio Frequency Cavity Technology section (SRF). You will be part of a small, dedicated team responsible for developing and implementing a new class of non-mechanical tuners for superconducting RF cavities, investigating both standalone cavity and integrated cryomodule solutions.

This is a challenging, multi-disciplinary project where you will take an active role in defining and assessing the integration and performance of a novel RF cavity tuning application. You'll be at the forefront of the development of a new frequency-tuning approach for SRF cavities, working on systems for both discrete RF frequency switching and continuous frequency modulation. Ultimately, your work will be applicable to CERN's Large Hadron Collider (LHC), the proposed Future Circular Collider (FCC), and the EU-funded Innovate for Sustainable Accelerating Systems (iSAS) program.

Eligibility criteria:

• You are a national of a CERN Member or Associate Member State.
• You have a professional background in RF engineering, superconducting RF (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.
