At CERN, the European Organisation 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.

Job description
You will contribute to a proposal covering the design, optimisation, and performance evaluation of a potential future collider at CERN. The role encompasses both beam optics development and beam dynamics simulations, including the study of key effects such as synchrotron radiation, beam-beam interactions, and impedance.
Your responsibilities
Contribute to the conceptual design phase of the study, supporting the development and assessment of the collider design.
Propose optimisations of the linear and nonlinear beam optics of the collider, including tune scans and multi-objective optimisation of the dynamic aperture, as well as optimising collider parameters to maximise machine performance and operational robustness.
Perform particle tracking studies for the collider across its operating energy range, including the effects of beam-beam interactions, synchrotron radiation, and beam impedance.
Investigate key accelerator physics challenges for the collider, drawing on experience from the FCC-ee study.
Your profile
Knowledge of beam dynamics in synchrotrons and/or storage rings.
Experience with some of the key beam dynamics effects relevant to lepton colliders, such as transverse coupling, beam-beam interactions, synchrotron radiation, or beam impedance.
Experience in setting up, performing, and interpreting particle tracking simulations for accelerator physics studies.
Skills
Experience with accelerator physics simulation and analysis tools, such as MAD-X, ELEGANT, pyAT, Xsuite, or equivalent software.
Experience in running and managing large-scale simulations on high-performance computing (HPC) systems.
Strong communication and collaboration skills, with the ability to work effectively in an international, multidisciplinary environment.
Ability to present technical and scientific results clearly, both orally and in writing.
Spoken and written English, with a commitment to learn French.
Eligibility criteria:
You are a national of a CERN Member or Associate Member State.
You have a professional background in 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.
What we offer
A monthly stipend between 6,372-7,004 Swiss Francs per month (tax free) depending on your degree.
30 days of paid leave per year plus 2 weeks' annual closure.
Coverage by CERN’s comprehensive health insurance scheme (for yourself, your spouse and children), and membership of the CERN Pension Fund.
Family, child and infant monthly allowances depending on your individual circumstances.
A relocation package (installation grant and travel expenses) depending on your individual circumstances.
Possibility to extend your contract up to 36 months.
On-the-job and formal training including language classes.
We've signed the Gradcracker feedback pledge.
(This means that we will supply feedback if requested after an interview.)
