ESS is now looking for a Radiation Transport Scientist for the ESS Spallation Physics Group organised within the Target Division as part of the Technical Directorate.

The ESS Spallation Physics Group has the responsibility to perform ESS wide all work in the area of particle transport physics and related subjects, with the exception of accelerator proton transport, neutron scattering instrument optics and detector response and dose to worker and public calculations. The duties of the ESS spallation physics group include, but are not limited to:


• Neutronics: Monte Carlo transport calculations (MCNP, Phits, Fluka, etc) and activation calculations (CINDER, Fispact, etc).
• Computer tools and cross-section development.
• Experimental verifications & developments.
• Study of materials of interest for the operation and upgrade of the facility.
• Interface to the neutron scattering instrument teams

Job description

The successful candidate will be part of the ESS Spallation Physics Group. As an experienced scientist the new employee will coordinate and work on shielding design and activation calculations. The new employee will interface with other parts of the organisation to support globally acceptable solutions for shielding design and activation of materials.

Your main areas of responsibilities as a Radiation Transport Scientist will be to:


• Work with engineering and construction workpackage managers and work unit leads across the organisation to provide radiation transport assessments and recommendations for the customers’ systems.
• Work with and guide younger team members who are assigned to the tasks lead by the successful candidate.
• Perform particle transport calculations and activation calculations for customers across the organisation. 

Qualifications

The successful candidate will have:


• PhD or equivalent experience in physics, chemistry or health physics.
• Advanced knowledge in radiation transport.
• Advanced knowledge in using the Monte Carlo particle transport codes like MCNP(X), Phits, Fluka, etc.
• Ability to obtain an MCNP(X) license.
• Experienced in applying variance reduction methods for deep penetration problems in Monte Carlo transport calculations.
• Experience in using analytical formulas for neutron and gamma transport calculations.
• Experience in using burn-up code like Cinder or FISPACT to perform inventory calculations.
• Fluent in English, oral and written
• Being able to communicate effectively and willingly in a multicultural environment.
• Willingness to show initiative.
• Being able to develop solutions for evolving designs and requirements.
• Team player that can work independently.

Desired qualifications are:


• License for MCNP(X)
• Experience in designing and/or operating of spallation sources.
• Experience in designing and/or operating of research facilities.
• Knowledge in C++.
• Knowledge of European languages other than English.

Duration & Location
The position is permanent with six months initial probationary period.

Your work place will be situated in Lund, Sweden.

Start date
