Your responsibilities

The Accelerators and Beam Physics Group within the Beams Department (BE) is responsible for studying and understanding the beam dynamics over the complete CERN Accelerator Complex through theoretical, simulation and experimental studies. 

In the position of Applied Physicist for Ion Beam Development you will dedicate your work to the ion source, which delivers primary ions for the CERN accelerator chain. Up to now mainly lead ions were delivered to the experiments. Future experiments are requesting now also lighter elements.

You will:

• Study the production of lighter elements at the source level, including the choice of the material (based on operational and safety aspects), the operational source parameters, source extraction simulations, stability and reliability studies;
• Improve the general reliability and simplify the ongoing operation 
• Participate in the operation of the source.

Your profile

Skills and/or knowledge

• Experience in ion tracking simulations with space charge;
• Experience in optical spectroscopy;
• Knowledge of ion production in plasmas;
• Knowledge of materials used in sources;
• Fluent in English, the ability to work in French would be an advantage.

Eligibility criteria:

• You are a national of a CERN Member or Associate Member State.
• You have a professional background in Physique (or a related field) and have either:
  • a Master's degree with 2 to 6 years of post-graduation professional experience;
  • or a PhD with no more than 3 years of post-graduation professional experience.
• You have never had a fellow or graduate contract before.

Job closing date: 17.09.2023 at 12:00 AM (midnight) CET.

Job reference: BE-ABP-HSL-2023-23-GRAP

Contract duration: 24 months, with a possible extension up to 36 months maximum.

Target start date: 01-January-2024

What we offer

• A monthly stipend ranging between 6194 and 6808 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.
• On-the-job and formal training at CERN as well as in-house language courses for English and/or French.

About us

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.
