Job Description

As a key member of the CERN team, you will contribute to the development and refinement of electromagnetic simulation models for the Proton Synchrotron (PS) and Super-Proton-Synchrotron accelerator (SPS). These models are crucial for estimating the longitudinal and transverse impedance contributions of both existing and new accelerator components.

Your primary responsibilities will include performing electromagnetic simulations in CST or other relevant tools to validate the design of new components and propose modifications to existing machine elements without impairing their functionality. You will work closely with a team that focuses on several critical tasks:

  • Contributing to and updating the models of existing machine elements, such as kickers and beam instrumentation components, to accurately represent the overall impedance for accelerators like the LHC, SPS, PS, and PSB.
  • Conducting RF measurements to assess the longitudinal and transverse impedance of machine elements before they are installed in the accelerators.

The objective of this impedance mitigation work is to reduce the impedance of both new and already installed equipment. Impedance studies play a fundamental role during the development and prototyping phases of new equipment, ensuring that impedance requirements are met and proposing mitigation strategies if necessary before finalizing the design with the equipment owners.

Required Skills and Knowledge

  • RF engineering and simulations of EM-field configurations (knowledge of basic beam dynamics would be an asset).
  • Basics of RF measurement techniques (knowledge of Python would be an asset).
  • 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 RF-engineering, 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.
