Applied Physicist in the field of Accelerators in the Technology Department (TE), Machine Protection and Electrical Integrity Group (MPE), Performance Evaluation Section (PE)

Within the TE Department, the MPE Group provides support to the operation of the accelerators and maintains state-of-the art technology for magnet circuit protection and interlock systems.

Avoiding accidental release of the energy stored in the beam or in the magnet system is one of the most challenging aspects in the operation of the LHC and in the design of future accelerators. Sophisticated and highly reliable protection systems are therefore required in order to safely operate such accelerators with beam energies exceeding 360 MJ and energies stored in the magnet system exceeding 1 GJ. Proper protection requires a thorough design of the protection architecture, based on detailed studies and simulations and finally realised using new techniques and sophisticated hardware. Safe protection is required through the entire operational cycle: during equipment tests, at injection, during operation with stored beam and during extraction.


As applied physicist in the TE-MPE-PE Section, you will:

  • Analyse data from beam and magnet operation of the LHC in order to understand and assess the performance of the protection systems and take part in magnet training campaigns.
  • Identify and study beam-related failure cases and derive specifications of protection systems for LHC upgrades and future accelerators.
  • Participate in the R&D on beam-induced damage of accelerator equipment.
  • Contribute to the activities to monitor and increase the reliability and availability of the LHC.
  • Participate in the first-line operational support concerning the LHC protection systems (both beam and magnet circuit related), in close collaboration with equipment owners and teams involved in operation.
  • Supervise and coach technical students, PhD students, and fellows.


Master's degree, PhD or equivalent relevant experience in the field of Applied Physics.
