Your responsibilities

In this role, you will join the Accelerator Systems Department (SY), more specifically a team in the Sources, Targets and Interactions Group, who is in charge of Beam-Machine Interaction studies. 
As such, you will contribute to the Physics Beyond Colliders initiative, an exploratory study aimed at exploiting the full scientific potential of the CERN's accelerator complex and scientific infrastructures through projects complementary to the Large Hadron Collider and other possible future colliders

You will: 

- work on energy deposition calculations with a realistic implementation of the FLUKA model to estimate the heat loads in the different equipment intercepting the beam;
- compute Beam loss measurement signals for setting appropriate thresholds during the beam tests, to evaluate the performance of the setup and to assess the expected radiation environment and its impact and possible mitigation on the electronics (R2E);
- carry out new benchmark studies for crystal-assisted heavy ion collimation;
- perform energy deposition studies for heavy ion losses, estimating the absorbed dose in the magnets to evaluate their lifetime;
- contribute to energy deposition studies for the HL-LHC collimation upgrades.

Your profile

Skills and/or knowledge

• Experience in Monte Carlo transport code usage (preferably FLUKA);
• Knowledge of programming techniques, languages and scripting (i.e. bash, python);
• Knowledge of accelerator physics and nuclear physics would be desired;
• 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 Applied physicist/Physics engineer (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: 22.08.2023 at 12:00 AM (midnight) CET.

Job reference: SY-STI-BMI-2023-44-GRAP

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

Target start date: 01-December-2023

This position requires:

• Work during nights, Sundays and official holidays, when required by the needs of the Organization.

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.
