Applied Physicist

Job Posting Organization:
CERN, the European Organization for Nuclear Research, is a leading scientific research institution established in 195

• It is located in Geneva, Switzerland, and is known for its groundbreaking work in particle physics. CERN operates the world's largest particle physics laboratory and employs thousands of scientists, engineers, and support staff from over 100 countries. The organization's mission is to uncover the fundamental structure of the universe by studying the basic constituents of matter and the forces that govern their interactions. CERN is renowned for its Large Hadron Collider (LHC) and is at the forefront of scientific research, contributing to our understanding of the universe's fundamental laws.

Job Overview:
The position of Applied Physicist at CERN is focused on advancing the field of accelerator physics, specifically in the area of beam loss detection. The successful candidate will join the Accelerator Systems Department, which is responsible for the technical systems related to beam operations in CERN's accelerators. This role involves significant contributions to the development of beam loss detectors for current and future accelerators, particularly the Future Circular Collider Electron-Positron (FCCee). The position requires a strong commitment to research and development, data analysis, and the ability to identify strategic directions for future technologies in beam loss monitoring. The candidate will work collaboratively within a team and will have opportunities to represent CERN at various academic and professional events.

Duties and Responsibilities:
The Applied Physicist will have a diverse set of responsibilities, including:

• Participating in the collection of specifications for beam loss detectors for the FCCee project.
• Studying the evolution of beam parameters and their impact on detection technologies.
• Defining the layout of beam loss detectors for FCCee.
• Performing simulations to evaluate detector responses across different technologies.
• Analyzing and interpreting measurement results, documenting findings, and disseminating outcomes through publications.
• Representing CERN at conferences, workshops, and outreach activities.
• Collaborating with team members to ensure effective communication and project progress.

Required Qualifications:
Candidates must possess a Master's degree or PhD in applied physics, engineering, or a related field, with relevant experience in beam instrumentation or beam loss detection. Demonstrated experience in data analysis, particularly in high-energy physics, is essential. Candidates should also have experience in the commissioning and operation of beam instrumentation systems, as well as the integration of new equipment into accelerator layouts. Technical competencies in gas-based particle detection technologies, experimental data analysis, accelerator performance optimization, and detector assembly and integration are required.

Educational Background:
A Master's degree or PhD in applied physics, engineering, or a closely related field is required for this position. The educational background should include a strong foundation in physics principles, particularly those related to particle physics and accelerator technology.

Experience:
Candidates should have substantial experience in data analysis, particularly in the context of beam loss measurements in high-energy physics environments. Experience in the commissioning and operational aspects of beam instrumentation systems is critical, as is familiarity with the integration of new technologies into existing accelerator frameworks. The ideal candidate will have a proven track record of working on complex scientific projects and contributing to research and development efforts.

Languages:
Fluency in spoken and written English is mandatory, and candidates should demonstrate a commitment to learning French as part of their professional development. Proficiency in additional languages may be considered an asset but is not required.

Additional Notes:
This position is a limited duration contract for 5 years, with the possibility of applying for an indefinite position under certain conditions. The role requires a commitment to a 40-hour work week and may involve working in radiation areas, during nights, Sundays, and official holidays, as well as interventions in underground installations. A valid driving license is also required for this position. The job grade is classified as 6-7, and the reference for this job is SY-BI-BL-2025-108-LDB.
