Survey Technician Job in Geneva, , Switzerland

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

Survey Technician Job Description

You will join:
 

• The EN Engineering Department provides CERN with the Engineering Competences, Infrastructure Systems and Technical Coordination required for the design, installation, operation, maintenance and dismantling phases of the CERN accelerator complex and its experimental facilities.
• The EN/ACE (Alignment, Coordination and Engineering) Group is responsible for planning and coordinating all maintenance and installation activities in the CERN Accelerator Complex, providing support to the experiments using the CERN accelerators, during their preparation, integration, installation and operation, and for the design installation and maintenance of the secondary beam zones. The Group is also responsible for the metrology and the alignment of accelerators and detectors components.
• The Large Scale Metrology (SU) section is responsible for the metrology and alignment of accelerators and detectors components. This involves the accurate positioning, the maintenance of the geodetic networks along the 63 km of beam lines and in the big experimental caverns at CERN. Its activities also include the dimensional quality checks of the accelerator and detector components before their installation, from their manufacturing to their assembly and calibration, when classical workshop metrology is inadequate. Inside this Section, a team is responsible of the alignment of the components located along the accelerators and transfer lines as well as the internal metrology of these components before their installation in the tunnels. This team is also responsible for the "as built" measurements of equipment and buildings using the laser scanner technology.

• Align all types of magnets in the CERN accelerator complex and in particular in the LHC long straight sections (LSS), write the corresponding survey reports, and manage the relevant documentation.
• Realize metrology measurements at all stages of the assembly of accelerator components using the laser tracker technology.
• Discuss the requests with the clients (equipment owners, physicists, etc.) and present them with the results.
• Ensure the availability and the good functioning of the instrumentation and the software provided to a contractor and follow-up on the work done by the contractor, including the data processing.
• Give feedback to improve the survey field procedures, methods and software.
• Calibrate the Electronic Distance Measurers (EDM) in the calibration base.
• Realise "as built" measurements of tunnels and buildings using the laser scanner technology.

• Some initial experience in the domain of high accuracy geodetic metrology.

• Use of high accuracy survey instruments (theodolites, total stations, optical & digital levers).
• Laser tracker measurements: basic use of the technology.
• Expert use of standard compensation software: basic use.
• Laser scanning: use of instruments and software.
• Use of Office software packages: Word, Excel, Powerpoint.

• English or French: spoken and written. The ability to understand and speak the other language (or willingness to learn it) in routine situations would be an advantage.

• Work in Radiation Areas.
• Interventions in underground installations.
• Shift work, when required by the needs of the Organization.
• Stand-by duty, when required by the needs of the Organization.
• Work during nights, Sundays and official holidays, when required by the needs of the Organization.
