Applied Physicist

Job Posting Organization:
CERN, the European Organization for Nuclear Research, was established in 1954 and is one of the world's largest and most respected centers for scientific research. With a mission to uncover the fundamental structure of the universe, CERN employs thousands of scientists, engineers, and support staff from over 100 countries. The organization operates the world's largest particle physics laboratory, where physicists and engineers work together to explore the basic constituents of matter. CERN's commitment to diversity and inclusion is a core value, and it actively promotes a diverse workforce as essential to its success.

Job Overview:
The position of Applied Physicist within the Vacuum, Surfaces and Coatings (VSC) Group at CERN involves a comprehensive engagement with the lifecycle of accelerator vacuum systems. The role requires the candidate to plan and execute measurement campaigns for particle accelerator vacuum components, perform simulations to support design and experimental parameters, and analyze data to document and report results. The successful candidate will also be involved in the development of vacuum systems for the Beam Screen Test Bench Experiment (BESTEX) at the Karlsruhe Research Accelerator, which includes preparing and commissioning experimental setups for photon-stimulated desorption and photoelectron yield measurements. This position is critical for the FCC-ee project, focusing on quantifying photon stimulated desorption induced by synchrotron radiation.

Duties and Responsibilities:

• Plan and conduct measurement campaigns for particle accelerator vacuum components.
• Perform simulations of synchrotron light distribution and vacuum conditions using tools like SynRad and MolFlow.
• Assemble and pre-align prototype beam screens and test objects in experimental vacuum chambers.
• Implement changes to measurement setups to facilitate characterization of novel beam screens.
• Operate setups and characterize properties of beam screens, ensuring accurate data acquisition and analysis.
• Prepare, install, and commission experimental setups for photon-stimulated desorption and photoelectron yield measurements at BESTEX.
• Collaborate with the KARA site team for installation and technical changes.
• Ensure proper vacuum conditions and commission control systems for experimental chambers.
• Document and report results of experiments and simulations.

Required Qualifications:
Candidates must be nationals of a CERN Member or Associate Member State and possess a professional background in Physics or Materials Science/Engineering (or a related field). The ideal candidate will have either a Master's degree with 2 to 6 years of post-graduation experience or a PhD with no more than 3 years of post-graduation experience. Additionally, candidates must not have previously held a CERN fellow or graduate contract.

Educational Background:
A Master's degree in Physics, Materials Science, Engineering, or a closely related field is required. A PhD in a relevant discipline is also acceptable, particularly for candidates with less professional experience.

Experience:
The position requires a professional background with a minimum of 2 years of experience for Master's degree holders or up to 3 years for PhD holders. Experience in ultra-high vacuum systems, computer-based simulation, and experimental setups is essential. Familiarity with data analysis and control software is also necessary.

Languages:
Fluency in spoken and written English is mandatory, with a commitment to learn the basics of French being advantageous. Proficiency in additional languages may be beneficial but is not required.

Additional Notes:
The contract duration is 24 months, with a possible extension up to a maximum of 36 months. The position requires a commitment of 40 hours per week and may involve work in radiation areas, underground installations, and during nights, Sundays, and official holidays as needed. Candidates must obtain medical clearance due to occupational health risks associated with the position. The monthly stipend ranges from 6287 to 6911 Swiss Francs (net of tax), and benefits include comprehensive health coverage, paid leave, and training opportunities.
