Radio Frequency engineer (SY-RF-SRF-2023-111-GRAP)

  • Full-time

Job Description

Your responsibilities

As a Radio Frequency Engineer, you will join the Accelerators Systems Department (SY), which is responsible for the accelerator beam-related technical systems. This position is located in the Radio Frequency Group where you would join the team which is responsible for all superconducting cavities and cryomodules in the CERN accelerator complex.

In this role, you will work on the fabrication and testing of crab cavities to be installed in the future HL-LHC. More specifically, you will:

  • Follow up on the fabrication of SRF Crab cavities in the industry; 
  • Review and approve fabrication reports;
  • Follow up on Radio Frequency measurements during fabrication of SRF Crab cavities;  
  • Gradual takeover of responsibility for multiphysics simulations and data analysis to validate measurements and None-conformance reports related to crab cavities manufacturing and testing;
  • Perform warm and cold (2 K) Radio Frequency measurements of Crab cavities and cryomodules at CERN;
  • Coordinate activities inside CERN with different departments for the qualification and or preparation of SRF cavities.

Your profile

Skills and/or knowledge

  • Demonstrated knowledge of SRF cavity fabrication techniques with a primary focus on deflecting/crab cavities;
  • Experience with Multiphysics simulations tools (CST, HFSS, etc.);
  • Experience with RF measurements at 2K of SRF cavities;
  • Knowledge of cost, quality, and schedule control
  • Knowledge of Python is 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 electrical engineering or RF engineer (or a related field) and have either:
    • a Master's degree with 2 to 6 years of post-graduation professional experience;

About us

At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world's largest and most complex scientific instruments, they study the basic constituents of matter - fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact, and provides insights into the fundamental laws of nature. Find out more on
