Offer Description

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.

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, focusing on flattop luminosity production including beam-beam effects.
• Analyse the impact of the aforementioned parameters on the beam halo formation.
• 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 Ph D with no more than 3 years of post-graduation professional experience.
• You have never had a CERN fellow or graduate contract before.
