Job ref: EN-EA-LE-2019-128-LD


As a Beam Physicist, you will be responsible for the exploitation of secondary and tertiary beams in the CERN accelerator complex. You will set up, adapt, and develop particle beams, participate in the design of experimental facilities, directly interact with the experiments and collaborate and guide the operations team to optimally exploit the beamlines according to the needs of experiments.

In particular, you will be expected to:

  • Take responsibility for the exploitation of the secondary beams in the PS East and SPS North Areas and in the CERN accelerator complex, ensuring that the beams operate at high efficiency to fulfil the yearly physics programme;
  • Perform particle beam design studies (optics, simulations, background conditions), ensure their readiness and optimize the beams for the needs of the experiments;
  • Resolve interface issues and liaise with the experiments for the optimal exploitation of the beam lines in line with the respective physics goals;
  • Discuss with users to understand their requirements in terms of secondary and tertiary beam characteristics, ensure the requirements are in line with existing beam lines, study and propose upgrades whenever necessary;
  • Provide guidance and work in close collaboration with the PS and SPS operations teams to ensure the optimal exploitation of the beam lines and ensure the best support to the experimental teams;
  • Contribute to the modernisation process of all beam related design software tools and in the preparation of hardware consolidation of the beam lines;
  • Write and contribute to software used for the high-level control or analysis of the beam lines;
  • Document the beam lines and report to the relevant committees;
  • Collaborate with the radioprotection and safety teams to ensure the safe operation of the beam lines, particularly for the experimental teams;
  • Supervise students and technicians as required by on-going projects and activities.

PhD in the field of physics.


  • Extensive experience in experimental high-energy particle physics and knowledge of particle detectors;
  • Working with modern simulation tools widely used in particle and accelerator physics and capability for data analysis;
  • Experience in radiation protection issues, in particular, related to particle beams and accelerators, and methods used to mitigate the risks;
  • Experience in programming and modelling of particle or nuclear physics processes is essential;
  • Knowledge of safety issues in particle accelerators, underground installations and experimental areas, and practices used to mitigate the risks;
  • Knowledge of modern engineering or project management techniques is considered as an asset.

Technical competencies:

  • Simulation, design and development of primary and secondary beam lines;
  • Simulation, design and development of (parts of) detectors;
  • Knowledge and application of beam optics (rings and transfer lines), (transfer or secondary lines);
  • Knowledge of programming techniques and languages (physics and beam related programming including data analysis);
  • Knowledge of particle matter interaction and respective physics processes;
  • Monte-Carlo techniques, transport codes and respective physics model
