Applied Physicist (BE-BI-EA-2019-92-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

Job Description


Are you skilled in detector design, simulation and operation? Are you up for the challenge of developing instrumentation for accelerators at the high energy and intensity frontier? Take Part!

CERN is looking for talented individuals specialising in applied physics to join its Beams Department, which hosts the Groups responsible for beam generation, acceleration, diagnostics, controls and performance optimisation. This position will be in the Beam Instrumentation Group where you will take part in developing, testing, commissioning and maintaining the diagnostic devices used to deliver beams to CERN’s experimental areas.


Your main task will be to develop, test, produce, operationally deploy and maintain the instrumentation and diagnostic systems used to measure the secondary beams in the CERN experimental areas, which will undergo a large consolidation campaign over the next 5 years. In addition, you will be expected to contribute to other activities within the Group, in particular the development and operation of electron coolers and electron lenses.

The job will involve:

  • Designing the detectors and readout electronics for scintillating fibre monitors as part of the CERN North Experimental Area consolidation project.
  • Simulating and analysing detector performance.
  • Building, testing and managing the series production of these detectors.
  • Installing, commissioning and maintaining large scale systems throughout the CERN experimental areas.
  • Contributing to the development and testing of electron coolers and electron lenses.


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


  • Demonstrated experience in the field of applied physics with emphasis on the design, construction and testing of experimental beam line detectors.
  • Experience in the field of gas based and optical particle detection technologies and related read-out electronics will be an advantage.

Technical competencies:

  • Analysis and optimization of detector performance.
  • Assembly and integration of detectors.
  • Operation and support of experimental facilities.
  • Testing and validation of detector, accelerator and beam line components.
  • Simulation, design and development of (parts of) detectors.

Behavioural competencies:

  • Achieving Results: delivering high quality work on time and fulfilling expectations.
  • Working in Teams: building and maintaining constructive and effective work relationships; working well in groups and readily fitting into a team; participating fully and taking an active role in team activities.
  • Demonstrating Flexibility: demonstrating openness to new ideas and situations; being willing to work on different projects simultaneously.
  • Solving Problems: identifying, defining and assessing problems, taking action to address them; finding the information needed to solve problems; making objective judgments based on all the facts available.
  • Learning and Sharing Knowledge: keeping up-to-date with developments in own field of expertise and readily absorbing new information; sharing knowledge and expertise freely and willingly with others; coaching others to ensure knowledge transfer.

Language skills:

Spoken and written English or French: ability to draw-up technical reports and to make oral presentations in at least one of the two languages. Basic knowledge of the other language or a willingness to acquire it rapidly.
