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.

Diversity has been an integral part of CERN’s mission since its foundation and is an established value of the Organization.

Job Description

The experiments at the LHC will be upgraded to cope with the increased collision rates in the High Luminosity LHC (HL-LHC) era that is foreseen to start in 2029.

As Radiation Protection Physicist, you will

  • perform radiation protection assessments contributing to the design of the LHC experiments upgrades for HL-LHC operation. The assessments will focus on the exposure of personnel during interventions in future Long Shut-downs as well as the activation of detector components and the related activation zoning of the experimental caverns;
  • perform simulations with the FLUKA Monte Carlo radiation transport code, coupled to the in-house developed SESAME and DORIAN codes;
  • write analysis code for these assessments;
  • participate in the further development of the SESAME and DORIAN codes.

In this role, you will be integrated in the CERN operational radiation protection team and involved in operational tasks, such as radiation measurement campaigns, and thereby gain experience in the operation of particle collider experiments. Finally, you will have the opportunity to take over operational radiation protection responsibilities.


Eligibility criteria:

  • You are a national of a CERN Member or Associate Member State;
  • You have a Master’s degree and between 2 and 6 years’ experience or PhD with up to 3 years of relevant experience in Nuclear Physics/Engineering or High Energy Physics or other related field;
  • You should have a working knowledge of English or French.

Skills and/or knowledge:

  • Radiation Protection concepts;
  • Monte Carlo simulation codes for radiation transport;
  • Programming skills (python, C++, FORTRAN);
  • Source code configuration management systems;
  • Data analysis;
  • Excellent interpersonal and communication skills.

Additional Information

What we offer:

  • An employment contract of in principle 24 months, with a possible extension up to 36 months;
  • On-the-job and formal training at CERN as well as in-house language courses for English and/or French;
  • A monthly stipend ranging between 6050 and 6650 Swiss Francs per month (net of tax);
  • Coverage by CERN’s comprehensive health scheme (for yourself, your spouse and children), and membership of the CERN Pension Fund;
  • Depending on your individual circumstances: installation grant; family, child and infant allowances; payment of travel expenses at the beginning and end of contract;
  • 30 days of paid leave per year.

How to Apply:

You will need the following documents to complete your application:

  • A CV;
  • A scanned PDF of your most recent relevant qualification;
  • We recommend to add two recent letters of recommendation, giving an overview of your academic and/or professional achievements. You can upload these letters at the time of application if you have them to hand. You will also be provided with a link as soon as you have submitted your application to forward to your referees to upload their letters confidentially.

The earliest expected start date for selected candidates is May 2023.
