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

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

Job Description

The AWAKE ( experiment at CERN studies advanced proton driven wake field acceleration for future particle physics applications. The second phase of the experimental program, called AWAKE RUN2, requires a new electron injector, capable of producing very short bunches and excellent beam quality. The design is based on an S-band RF-photo injector combined with x-band acceleration and velocity bunching.

  • You will contribute to further optimize the baseline design with particular emphasis on performance and potential cost savings. A reduced prototype of such an injector is currently built at CERN, and you will participate in the completion of this prototype injector and the commissioning with beam as well as its performance demonstration;
  • Finally, you will participate in the operation of the RUN 1 injector installed in the AWAKE experiment.


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 accelerator physics or other related field;
  • You should have a working knowledge of English or French.

Skills and/or knowledge:

  • Good knowledge of accelerator physics in particular RF engineering and beam dynamics;
  • Experience with numerical simulations (PIC for beam dynamics, FEM for RF devices);
  • Basic programming skills for example in C++, Python or MatLab;
  • Hands on experience with accelerator components or operation;
  • Team work, good 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.

Ready to take part? Then please submit your application by 23 January 2023 at  midnight (12.00 AM CEST).
