Vacuum technician for the design and operation of vacuum systems in the Technology Department (TE), Vacuum Surfaces and Coatings group (TE-VSC), Beam Vacuum Operation (TE-VSC-BVO).


You will join:

The Beam Vacuum Operation (BVO) section, taking care of the design and procurement, assessment and assembly, operation and maintenance of most of the CERN's vacuum systems. The vacuum test laboratory provide characterization of accelerator equipment by means of outgassing measurement and residual gas analysis. In addition to interventions in the accelerators, the tasks encompass assessment of ultrahigh vacuum components, evaluation of performance of getter coatings, and qualification of materials and surface finishing for vacuum application. 



As a Vacuum Technician in the TE-VSC-BVO Section, you will:

  • Install vacuum equipment in the CERN's accelerators and test tightness by helium leak detection.
  • Monitor the pressure profile recorded by vacuum gauges, in particular in the LHC's cryogenic beam pipes.
  • Test vacuum components prior to installation by pumping speed and outgassing rate measurement, and residual gas analysis.
  • Participate in the design of vacuum equipment.
  • Procure ultrahigh vacuum pumps and components, writing functional and detailed specifications.
  • Participate in the accelerators' maintenance and consolidation programmes.
  • Provide writing reports of measurement tests and accelerator interventions.
  • Participate in the regular stand-by duty service of the VSC group.


Qualification required

Higher technical diploma in the field of mechanics, measurements, material instrumentation, chemical or equivalent experience.
