Accelerator Physicist, potential future collider

Big Science Sweden; Genf; Hybrid; CHF 100,000 - 150,000; Full time

Job summary

CERN in Geneva invites applications to contribute to a proposal for the design, optimisation, and performance evaluation of a potential future collider. The role covers beam optics development and beam dynamics simulations, including synchrotron radiation, beam-beam interactions, and impedance.

You will support the conceptual design, propose linear and nonlinear optics optimisations, and perform particle tracking across energy ranges to maximise machine performance and robustness.

Qualifications

• Master's degree with 2–6 years of professional experience since graduation, or PhD with up to 3 years since graduation.
• Bachelor's degree alone is not eligible.
• CERN fellow or graduate contract applicants are not eligible.

Responsibilities

• Contribute to the conceptual design phase of the study for the collider design.
• Propose optimisations of linear and nonlinear beam optics, including tune scans and dynamic aperture optimization.
• Perform particle tracking studies across the operating energy range, including beam-beam, synchrotron radiation and impedance effects.
• Investigate accelerator physics challenges drawing on experience from related collider studies.

Mer information

What you'll do

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.

Be sure to meet the eligibility criteria

• You are a national of aCERN Member State or Associate Member State. Currently, we cannot consider applications from Pakistani, Lithuanian, Latvian, Cypriot and Croatian nationals, as the ceiling defined under Article II.5 of the Associate Membership Agreement has been reached.
• By the application deadline, you have a master’s degree with 2 to 6 years of professional experience since graduation or a PhD with a maximum of 3 years of professional experience since graduation. You are not eligible with only a bachelor’s degree.
• You have never had a CERN fellow or graduate contract before.
• Please pay attention to the additional criteria and requirements for this specific position and mentioned above.
