Job Description

Your responsibilities

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.

As an RF engineer, you will:

  • Follow up the fabrication of SRF Crab cavities in industry; review and approve fabrication reports in MTF;
  • Follow up RF measurements during fabrication of SRF Crab cavities in industry;
  • Perform warm and cold (2 K) RF 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:

Experience:

  • Experience with RF measurements of RF equipment, particularly SRF cavities, is an asset;
  • Knowledge of SRF cavity fabrication techniques;
  • Knowledge of Python programming;
  • Understanding of cost, quality, and schedule control principles.

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

Diversity has been an integral part of CERN's mission since its foundation and is an established value of the Organization. Employing a diverse workforce is central to our success.
