Junior Mechanical Technician (BE-RF-PM-2019-22-LD)

  • Geneva, Switzerland
  • Contract

Company Description

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 http://home.cern.

Job Description


Are you an enthusiastic Junior Mechanical Technician looking to acquire RF power experience whilst working on complex RF problematics? CERN, take part!

You will join:

  • The Beams Department (BE), which hosts the Groups responsible for beam generation, acceleration, diagnostics, controls and performance optimisation.
  • The Radio-Frequency Group (BE-RF), responsible for the RF Acceleration and Transverse Damping Systems for CERN accelerators. Our team operates the RF systems of existing accelerators and participates in the design of future accelerators and upgrades of existing machines.
