Process Operator in Cryogenic Test Facility (TTE Programme)

Updated: 2 months ago
Job Type: FullTime
Deadline: 06 Dec 2020

Are you an enthusiastic technician looking for a challenging professional experience to further your career?  If so, joining CERN’s TTE programme may very well give you that challenge.  

Come and join the team of cryogenics operation  of the SM18 test facility in the Technology Department. The group is responsible of the design, construction, operation & maintenance of cryogenic systems for accelerators and detectors. It is a unique opportunity to work and contribute to test the new generation of magnets and radiofrequency cavities for High Luminosity LHC project (upgraded LHC).

CERN is the world's largest particle physics laboratory and its flagship accelerator, the Large Hadron Collider, depends on having an unrivalled set of cryogenic systems on hand to guarantee reliable operation. The SM18 is one of the most important infrastructure to test sets of superconducting components able to operate in the CERN accelerators.

Typical cryogenic systems comprise compressors, heat exchangers, valves, instrumentation, vacuum pumps, controls and various test benches for cables, magnets and RF cavities. Process gas purity is essential.

From start-up and routine operation to maintenance support and emergency operation interventions, key point stands in maintaining the highest availability for the cryogenics equipment and reaches the SM18 target: allowing efficient tests for all the requested magnets and radiofrequency cavities within the allocated time while respecting safety, quality, priorities and procedures.

The experience you will gain as a member of the SM18 cryogenics operation team could not be acquired anywhere else, teaching you to work autonomously and to respond to all manner of situations around complex processes.


As member of the Cryogenics team, you will:

  • Be part of a team which runs the cryogenics testing facilities supporting the tests of cables, magnets and RF cavities developed and qualified by CERN at the SM18 testing facility for future upgrade of the LHC machine in the Hi Lumi project;
  • Participate to the ramp-up of a brand new helium liquefier commissioned and started in 2020;
  • Contribute to the continuous optimization of the cryogenics process and communicate about possible operation upgrades;
  • Integrate a multinational team with a range of skills and expertise;
  • Get the chance to broaden your knowledge into new areas;
  • Receive specific training and support for your professional development.

After a period of training, you will take on responsibility, on the ground and remotely, for operating the cryogenic system e.g.: trouble-shooting, emergency operation interventions, maintenance support, follow-up of contractor operation team depending on requirements and situations, updating the operating procedures, in particular with respect to the safety rules; and managing technical documentation.
