Applied Physicist - FCC-ee Collimation Studies (BE-ABP-NDC-2025-126-GRAP)
The Future Circular Collider (FCC) aims to be the next generation of high-performance particle colliders, succeeding the Large Hadron Collider (LHC). A key challenge for the FCC-ee is its stored beam energy, which is about two orders of magnitude higher than in previous lepton colliders, making even minor beam losses potentially damaging to accelerator components.
Beam collimation presents unprecedented challenges for this collider. A highly efficient system is required to ensure reliable operation, minimize background noise for experiments, and maintain safety in case of unforeseen beam losses.
In this role, you will:
1. Assist in improving the initial design of the FCC-ee collimation system to safely dispose of predicted beam losses and reduce background for experiments.
2. Conduct performance and Machine-Detector Interface (MDI) studies for various beam loss scenarios, iterating on the collimation system design.
3. Enhance existing simulation codes to assess collimation performance in lepton machines.
4. Collaborate with internal and external teams, providing input on beam losses, collimator design, and detector background studies.
5. Participate in beam measurements at operational machines like Super KEKB in Japan or the LHC, applying this knowledge for further experience and code benchmarking.
Your profile
Skills:
* Basic knowledge of Accelerator Physics.
* Experience with simulation tools such as X-suite, Mad-X, Geant4, and their coupling with beam dynamics codes is advantageous.
* Familiarity with beam dynamics and particle-matter interaction tools.
* Proficiency in Python programming is a plus.
* Fluency in spoken and written English or French, with a willingness to learn the other language.
* Educational background in Applied Physics or a related field, with either:
o a Master's degree with 2 to 6 years of post-graduate professional experience, or
o a PhD with up to 3 years of post-graduate professional experience.
* Applicants must not have previously held a CERN fellow or graduate contract.
Contract duration: 24 months, with potential extension up to 36 months.
Working hours: 40 hours/week.
