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 employs thousands of scientists, engineers, and support staff from over 100 countries, making it a hub of international collaboration in the field of science. The organization operates multiple research facilities and experiments, including the Large Hadron Collider, and is dedicated to pushing the frontiers of knowledge and technology in understanding the fundamental constituents of matter and the forces that govern their interactions.

Job Overview:
As an Applied Physicist at CERN, you will be an integral part of the Superconducting RF Cavity Technology (SRF) Section within the Radio Frequency (RF) Group of the Accelerator Systems (SY) Department. This role involves engaging in the design, maintenance, and enhancement of superconducting RF cavity systems utilized in CERN's accelerators. You will work closely with a small team focused on researching and developing superconducting RF materials, aiming to enhance the performance of superconducting thin films deposited on copper for SRF applications. This work is particularly crucial for the Future Circular Collider (FCC) project. Your responsibilities will include conducting RF measurements at cryogenic temperatures, developing diagnostic tools, and performing data analysis to correlate coating parameters with superconducting properties. This position offers a unique opportunity to contribute to cutting-edge research and development in the field of applied physics, with a focus on superconductivity and RF technology.

Duties and Responsibilities:
The duties and responsibilities of the Applied Physicist include conducting RF measurements at cryogenic temperatures on 1.3 GHz single cell cavities, performing RF measurements of flat samples using a quadrupole resonator, and developing diagnostic tools for thermal and magnetic mapping. You will also be responsible for data analysis and correlation analysis related to coating parameters and standard DC superconducting quantities. Additionally, you will collaborate with team members to enhance the performance of superconducting RF materials and contribute to the overall research and development efforts within the SRF Section.

Required Qualifications:
Candidates must be nationals of a CERN Member or Associate Member State and possess a professional background in Applied Physics, Electronics Engineering, or a related field. The required qualifications include 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. It is essential that candidates have not previously held a CERN fellow or graduate contract. Furthermore, experience with RF measurements, data analysis, and laboratory work is highly desirable, along with familiarity with Python and cryogenic systems.

Educational Background:
The educational background required for this position includes a Master's degree or PhD in Applied Physics, Electronics Engineering, or a closely related field. Candidates should have a strong foundation in classical electrodynamics, RF measurement techniques, and RF superconductivity theory, which will be beneficial for the role.

Experience:
The position requires candidates to have relevant experience in RF measurements and data analysis, as well as hands-on laboratory experience. Cleanroom experience is considered an advantage. Additionally, familiarity with finite element electromagnetic simulation software is beneficial, and candidates should have a commitment to learning and improving their skills in the field.

Languages:
Proficiency in spoken and written English or French is mandatory, with a commitment to learn the basics of the other language being advantageous. This bilingual requirement reflects CERN's diverse and international working environment, where effective communication is essential.

Additional Notes:
This position is fully onsite and involves working in radiation areas, requiring a valid driving license and medical clearance due to occupational health risks. The contract duration 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, and the target start date for this position is March 1, 202

• The compensation includes a monthly stipend ranging from 6287 to 6911 Swiss Francs, tax-free, along with 30 days of paid leave per year, comprehensive health insurance coverage, family allowances, and a relocation package depending on individual circumstances. Additionally, on-the-job and formal training, including language classes, will be provided.
