Interested in working on superconducting radio-frequencies? Want to get involved in constructing and testing high performance superconducting radio-frequency cavities for CERN’s particle accelerators? And what about getting involved in the future projects? Take Part!

You will join the RF group which is responsible for RF technology and the operation of the RF systems in all the particle accelerators, along with upgrades and new projects. An important activity is the construction, test and operation of Super-Conducting RF (SCRF) cavities, where particularly high standards of cleanliness are required during manufacture and assembly. CERN’s present clean room and RF test facilities date from the early 1980s and the construction and test of the SCRF cavities for LEP, with minor upgrade for the LHC cavities. A number of important new projects and upgrades based on SCRF cavities are now under way or will start soon. These include the construction of a new Super-Conducting post accelerator for the ISOLDE Rare Ion Beams (RIB) facility, known as High Intensity Energy (HIE) ISOLDE and construction of a prototype four-cavity cryomodule for a high beam intensity high gradient Super-Conducting Proton Linac (SPL). A substantial upgrade program has now been initiated to bring CERN’s clean rooms, diagnostic and RF test facilities to the standards required for the successful realization of the state-of-the-art high performance cavities and cryomodules which are essential to these projects. Included in this upgrade are refurbishment of existing clean rooms, construction of new clean rooms and assembly areas as well as the installation of new equipment for cavity treatment, cleaning and RF testing.


As RF-Engineer/Applied Physicist in the KS section, you will develop and deploy new diagnostic equipment and procedures, carry out RF test of cavities and cryomodules, participate in the LHC RF system operation and assist in the upgrade of CERN’s SCRF clean room assembly and test facilities. This will involve:

  • Participating in the upgrade of CERN’s SCRF test facilities and infrastructure. This includes the cryogenics system upgrade, refurbishment of clean rooms and the commissioning of new systems for cavity treatment, processing and diagnostics.
  • Assisting in the exploitation of the facilities for the fabrication and test of moderate and high field cavities.
  • Leading the development of new diagnostics systems for high gradient cavities.
  • Organizing cavity preparation, assembly, carrying out RF measurements and analysing the results.
  • Doing/supervising precision clean room assembly of RF components.
  • Participating in the LHC RF system operation and being part of the standby service.
  • Collaborating with other institutes working on SCRF for new accelerators in order to share experience and identify common solutions and future developments.

Qualification required

University degree in Electrical Engineering or Physics, a Ph.D would be preferential.

Experience and competencies

The experience required for the post are:

  • Demonstrated experience in the fields of: Superconductivity and Radio Frequency Superconductivity.
  • Cryogenics and vacuum.

  • Working with the relevant quality control standards and procedures.


The technical competencies you will need to take up the post are:

  • RF measurement techniques.
  • Precision assembly and construction.
  • Assembly in clean rooms.


The behavioural competencies you will have to demonstrate are:

  • Demonstrating Accountability; working conscientiously and reliably.
  • Achieving Results; having a structured and organized approach towards work.
  • Working in Teams; working well in groups and readily fitting into a team, building and maintaining constructive and effective work relationships.
