You will contribute to a proposal covering the layout, optics design, performance optimisation and evaluation of a potential future collider at CERN, the Linear Collider Facility @ 380 GeV (LCF380).
Your responsibilities
- Work on various design aspects of LCF380.
- Perform beam dynamics simulations to demonstrate its performance.
- Investigate the interaction regions (optics design, layout, for a possible dual beam delivery system) and the damping rings to optimise performance.
- Contribute to writing the summary design report.
Your profile
- Knowledge and understanding of lepton beam dynamics and optics design, including synchrotron radiation.
- Knowledge and experience in the setup, analysis and interpretation of particle tracking studies.
- Analysis of experimental data.
Skills
- Accelerator physics codes like MAD, Xsuite, ELEGANT, pyAT, GuineaPig, etc.
- Running simulations on an HPC.
- Good presentation skills.
- 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.
