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 probe 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, primarily in Europe, and is known for its groundbreaking work in particle physics, utilizing the world's largest and most complex scientific instruments to study fundamental particles and their interactions.

Job Overview:
The Applied Physicist position within the High Field Magnets (HFM) Programme at CERN focuses on advancing accelerator magnet technologies for future energy-frontier circular colliders. The role involves collaboration with international partners to enhance Nb₃Sn superconducting wires, aiming for improved performance through innovative wire designs and microstructural optimization. The successful candidate will engage in designing studies, conducting quantitative image analysis, and analyzing phase transformations and diffusion processes during heat treatment. Additionally, the role includes assessing mechanical deformation of wires and cables, as well as developing and conducting cryogenic electromagnetic tests of superconductors, contributing significantly to the advancement of superconducting technologies.

Duties and Responsibilities:
The Applied Physicist will be responsible for a variety of tasks including:

• Designing and conducting studies to guide the development of superconducting wires in collaboration with manufacturers and research institutes.
• Performing quantitative image analysis of superconducting wires to derive meaningful conclusions.
• Analyzing phase transformations and diffusion processes that occur during the heat treatment of materials.
• Assessing the mechanical deformation of wires during cabling and of cables under transverse stress, utilizing both experimental methods and modeling techniques.
• Developing and executing cryogenic electromagnetic tests on superconductors, such as critical current and magnetization tests, and analyzing the resulting data to inform future developments.

Required Qualifications:
Candidates must possess a professional background in Physics, Materials Science, or a related field. Essential qualifications include experience in image analysis, a solid understanding of materials science principles including phase equilibria and deformation, and proficiency in scripting for data analysis and automation. Desirable qualifications include knowledge of applied superconductivity, experience with finite element modeling, and familiarity with developing electrical tests. Candidates must also be nationals of a CERN Member or Associate Member State and should not have previously held a CERN fellow or graduate contract.

Educational Background:
The position requires candidates to have 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. This educational background should be in Physics, Materials Science, or a closely related field, ensuring that candidates have the necessary theoretical and practical knowledge to excel in the role.

Experience:
The ideal candidate should have a minimum of 2 years of relevant professional experience post-graduation if holding a Master's degree, or up to 3 years if holding a PhD. This experience should be directly related to the field of applied physics or materials science, particularly in areas relevant to superconductivity and magnet technologies.

Languages:
Fluency in spoken and written English or French is mandatory, with a commitment to learn the basics of the other language being highly desirable. This bilingual capability will facilitate effective communication within the diverse international environment at CERN.

Additional Notes:
The contract duration for this position is 24 months, with the possibility of extension up to a maximum of 36 months. The working hours are set at 40 hours per week, with a target start date of December 1, 202

• The position offers a competitive monthly stipend ranging from 6287 to 6911 Swiss Francs (net of tax), along with comprehensive health coverage for the employee and their family, membership in the CERN Pension Fund, and various allowances depending on individual circumstances. Employees are entitled to 30 days of paid leave per year and will have access to both on-the-job and formal training opportunities, including in-house language courses.
