Applied Physicist for Beam-beam and DA optimisation (BE-ABP-INC-2024-175-GRAP)

This position is focused on optimising the dynamic aperture (DA) and beam-beam collisions of the HL-LHC. This is to be achieved through studying and improving magnet field quality (FQ) and sorting activities.

The selected candidate will work on the following topics:

  • Study of sorting scenarios for the new HL LHC magnets with particular emphasis on prioritization of the sorting criteria (transfer function errors and field quality).
  • Follow up of the quality of magnets (transfer function and field quality) in view of defining their slot allocation and assess of their impact on the machine dynamic aperture.
  • Use the outcome from the sorting scenarios and slot allocation to study HL LHC operational scenarios in terms of dynamic aperture. The studies should naturally focus to the flattop luminosity production hence including beam-beam effects (e.g. luminosity levelling strategy, filling schemes and crab cavities configuration) together with the overall machine settings (tunes, chromaticity and octupoles).
  • Analyse the impact of the aforementioned parameters (e.g., measured field quality, sorting scenarios, beam-beam effect, octupoles...) on the beam halo formation.

Your profile

Skills

  • Numerical tools (python)
  • Non-linear beam dynamics and incoherent effects for synchrotron rings and colliders
  • Fluent in English, the ability to work in French would be an advantage.
  • You have a professional background in Applied physics (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 CERN fellow or graduate contract before.

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

Working hours: 40 hours per week

Job reference: BE-ABP-INC-2024-175-GRAP

Field of work: Applied Physics

What we offer

  • A monthly stipend ranging between 6287 and 6911 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.

We are on a Quest. A Journey into discovery like no other. Bring your expertise to our unique work and develop your knowledge and skills at pace. Join world-class subject matter experts on unique projects, in a Quest for greater knowledge and deeper understanding.

Begin your CERN Quest. Take Part

Diversity has been an integral part of CERN's mission since its foundation and is an established value of the Organization. Employing a diverse workforce is central to our success.
