Principal 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 centres 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 in multiple countries and is known for its groundbreaking work in particle physics, utilizing the world's largest and most complex scientific instruments to study the basic constituents of matter. CERN's commitment to diversity and inclusion is a core value, fostering a collaborative environment that enhances innovation and discovery.

Job Overview:
The Physics Beyond Colliders (PBC) initiative at CERN aims to expand the scientific reach of the accelerator complex by enabling innovative experiments that probe new frontiers in particle physics. This position offers a unique opportunity for a motivated researcher to engage in detailed electromagnetic simulations of novel PBC installations, quantifying their impedance impact on beam stability, and proposing or designing mitigation solutions as necessary. The role also involves the development and application of innovative measurement techniques, such as non-wire bench methods, to characterize complex PBC structures experimentally. Additionally, the successful candidate will advance the in-house Wakis code, extending its capabilities for PBC applications and benchmarking it against commercial solvers. The position also includes contributions to high-intensity beam studies in the injector complex, thereby broadening the project's impact.

Duties and Responsibilities:

• Carry out electromagnetic simulations of novel PBC devices and installations.
• Quantify the impedance impact of these structures on high-intensity beam stability.
• Contribute to the development of innovative experimental methods, including non-wire bench techniques, to characterize complex structures.
• Advance and benchmark the in-house Wakis code against commercial solvers, extending its capabilities for PBC applications.
• Propose or design mitigation solutions to ensure the safe integration of new experimental devices.
• Participate in high-intensity beam studies in the injector complex, supporting the PBC physics programme.

Required Qualifications:
Candidates must possess experience in electromagnetic simulations or accelerator physics. An understanding of beam dynamics or high-intensity beams is advantageous. The ideal candidate should demonstrate motivation to work at the intersection of novel physics experiments, simulation tools, and experimental techniques. Collaboration in a multidisciplinary and international team environment is essential.

Educational Background:
Applicants should have a professional background in Applied Physics or a related field. They must hold either a Master's degree with 2 to 6 years of post-graduation professional experience or a PhD with no more than 3 years of post-graduation professional experience. Additionally, candidates must be nationals of a CERN Member or Associate Member State and should not have previously held a CERN fellow or graduate contract.

Experience:
The position requires candidates to have relevant experience in electromagnetic simulations or accelerator physics, with a preference for those who have worked with high-intensity beams or beam dynamics. The experience level should align with the educational qualifications, ensuring that candidates have practical knowledge and skills applicable to the role.

Languages:
Proficiency in English, both spoken and written, is mandatory. Candidates should also demonstrate a commitment to learning French, which is considered beneficial for the role.

Additional Notes:
The contract duration is set for 24 months, with a possible extension of up to 36 months. The working hours are 40 hours per week, and the position offers hybrid job flexibility. The target start date for this role is 01-March-202
