Applied Physicist

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

• It is dedicated to advancing the frontiers of science and technology, particularly in the field of particle physics. CERN employs over 2,500 staff members and collaborates with thousands of scientists from around the world, representing more than 100 nationalities. The organization operates in multiple countries, primarily in Europe, and is known for its groundbreaking research and innovation in understanding the fundamental components of matter and the universe.

Job Overview:
The position of Applied Physicist at CERN focuses on simulation studies aimed at optimizing the performance of the n_TOF facility, which provides high-intensity neutron beams for nuclear astrophysics and medical applications. The successful candidate will engage in various simulation studies to enhance the facility's physics performance and contribute to the redesign of critical systems such as the collimation system and a neutron transmission measurement station. This role also involves quantifying and mitigating secondary radiation through optimized shielding configurations and design modifications. The candidate will utilize advanced Monte Carlo modeling techniques, specifically using FLUKA, to refine low-energy neutron transport and validate the latest neutron data libraries. Additionally, the position offers the opportunity to gain hands-on experience in the operations of experimental facilities as part of the local support team for n_TOF.

Duties and Responsibilities:

• Conduct simulation studies to optimize the physics performance of the n_TOF facility and its future programs.
• Redesign the collimation system and design a dedicated neutron transmission measurement station.
• Quantify and mitigate secondary radiation through optimized shielding configurations and design modifications.
• Utilize FLUKA for advanced Monte Carlo modeling, focusing on low-energy neutron transport, self-shielding effects, and Doppler broadening corrections.
• Perform neutronics validation and benchmarking of the latest neutron data libraries.
• Collaborate with the local support team for n_TOF and participate in the operations of experimental facilities.
• Engage in continuous learning and professional development within the field of neutron physics and related areas.

Required Qualifications:
Candidates must be nationals of a CERN Member or Associate Member State and possess a professional background in Physics or a related field. They should 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. Additionally, candidates must not have previously held a CERN fellow or graduate contract.

Educational Background:
The position requires a Master's degree in Physics or a related field, or a PhD in the same area. The educational background should include a strong foundation in physics principles, particularly in neutron physics and Monte Carlo simulations.

Experience:
Candidates should have experience in using Monte Carlo transport codes for physics experiments and performing studies in the field of neutron physics or neutronics. A background in advanced Monte Carlo modeling and familiarity with FLUKA is advantageous.

Languages:
Fluent spoken and written English is mandatory, and candidates should demonstrate a commitment to learning French, which is considered beneficial for the role.

Additional Notes:
The contract duration is 24 months, with the possibility of extension up to a maximum of 36 months. The position requires a commitment of 40 hours per week and offers hybrid working flexibility. The target start date for this position is September 1, 202

• The role may involve work in radiation areas, interventions in underground installations, and stand-by duty as required by the organization. Candidates may also be required to work during nights, Sundays, and official holidays based on organizational needs. The compensation includes a monthly stipend ranging from 6,372 to 7,004 Swiss Francs, which is tax-free, along with 30 days of paid leave per year, comprehensive health insurance coverage, family allowances, and a relocation package.
