Job Details

Job Posting Organization:
CERN, the European Organization for Nuclear Research, is a renowned international research organization established in 195

• It is located in Geneva, Switzerland, and is one of the world's largest and most respected centers for scientific research in the field of particle physics. CERN employs thousands of scientists, engineers, and support staff from over 100 countries, and its mission is to uncover the fundamental structure of the universe through advanced research and experimentation. The organization operates the world's largest particle accelerator, the Large Hadron Collider (LHC), and is involved in numerous international collaborations and projects aimed at advancing our understanding of matter and the universe.

Job Overview:
The position of Applied Physicist at CERN is designed for qualified and highly motivated individuals with a strong background in the simulation of radiation interactions with matter. The successful candidate will join a diverse team within the Accelerator Systems Department (SY), which is responsible for the technical systems related to beam operations in CERN's accelerators. The role involves significant contributions to the Future Circular Collider (FCC) design, particularly in the areas of particle shower simulations and the development of effective shielding solutions for synchrotron radiation. The Applied Physicist will work closely with accelerator beam physicists and mechanical engineers to ensure the successful design and operation of the FCC and its associated systems. This position offers an exciting opportunity to engage in cutting-edge research and development, contributing to the future of particle physics and accelerator technology.

Duties and Responsibilities:
As an Applied Physicist, the candidate will be responsible for several key functions, including:

• Designing the collimation system for the FCC by leading Monte Carlo studies of particle showers, collaborating with other physicists and engineers.
• Developing shielding solutions to mitigate synchrotron radiation in the collider and booster rings, ensuring radiation levels are kept within safe limits.
• Maintaining and enhancing machine models to improve Monte Carlo simulation tools.
• Supervising graduate students and interns in FCC-related calculations and documenting their findings.
• Collaborating on research and development activities within CERN and participating in international projects and collaborations.

Required Qualifications:
Candidates must possess a PhD or equivalent relevant experience in nuclear physics, particle physics, engineering, or a closely related field. Additionally, they should have demonstrated experience in particle-matter interactions, Monte Carlo simulations of particle showers, and the characterization of radiation environments in accelerators. Technical competencies should include simulation and design of particle accelerators, knowledge of electromagnetic radiation propagation, and the application of computational and mathematical physics. Strong analytical skills and the ability to optimize accelerator performance are also essential.

Educational Background:
A PhD or equivalent degree in nuclear physics, particle physics, engineering, or a related discipline is required for this position. The educational background should include extensive training in theoretical and experimental physics, particularly in areas related to particle interactions and radiation physics.

Experience:
The ideal candidate should have substantial experience in the field of particle-matter interactions, particularly in the context of accelerator physics. Experience with Monte Carlo simulations, especially in complex geometries, is crucial. Familiarity with the characterization of radiation environments in accelerators is also necessary, along with a proven track record of working on related projects or research.

Languages:
Proficiency in spoken and written English is mandatory, with the ability to understand and communicate in French being advantageous. Candidates should be capable of drafting technical specifications and scientific reports, as well as making oral presentations in at least one of the two languages.

Additional Notes:
This position is offered as a limited duration contract for a period of five years, with the possibility of applying for an indefinite position under certain conditions. The working hours are set at 40 hours per week, and the role may require work during nights, Sundays, and official holidays based on organizational needs. The job grade for this position is classified as 6-7, and it is referenced under job code SY-STI-BMI-2025-15-LD.
