Scientist (Chemist)

The Machine Directorate at the European Spallation Source (ESS) in Lund, Sweden, invites applications for a Chemist for Materials Group.

Description of division
The ESS Target Division is part of the ESS Machine Directorate with responsibility to design, develop, procure, install, commission and test the systems needed to convert the energetic proton beam coming from the accelerator to neutron beams that are utilized for experiments. The first step in this process is production of high energy neutrons through a spallation process involving the proton beam interaction with a tungsten target. The fast, high energy neutrons that are released in the spallation process are slowed down to the energies that are suitable for different types of experiments at ESS, and then delivered to the instruments through beam ports. Key features of the target station are the target itself, the neutron moderator and reflector system, and the neutron beam-extraction system.

The Materials Group is the part of the Target Division organization responsible for materials science and engineering support of the project activities for engineering the 5 MW target station, as well as carrying out research activities on particle irradiated materials properties. The Materials Group is aligned with the Materials Work Unit of the ESS Target Project Organisation, within the Physics Work Package.   

Main responsibilities



• Actively participating or leading scientific research activities within Materials Group

• Provide scientific and technical expertise in chemical aspects of Materials



• Taking part in the neutronics benchmark project, by planning and anayzing online measurements of the ortho-to-para ratio of cryogenic hydrogen for the cold neutron source

• Analysing the radiochemical processes in the target-moderator-reflector systems, and development of new materials in the moderator-reflector systems

• Analysing the corrosion mechanism for materials in the operational helium environment in the target monolith

• Analysing the effects of fluid impurities on the properties of materials exposed to it within the fluid systems, and collaborating on purification solutions with engineers designing fluid systems

• Managing the chemical composition data of materials for neutronics, shielding and engineering support

• Investigating diffusion and release properties of materials under intense proton and neutron irradiation, and supporting the safety analysis for licensing of the facility

    3. Collaborating with peers within the ESS organisation in Lund, as well as inkind partners and collaborating institutions, to deliver the ESS Construction Project

Qualifications



• Master in chemistry (Ph.D. preferred) or an equivalent combination of education and experience in chemical phenomena in nuclear materials

• Experience in working at an accelerator or nuclear facilities, preferably in the field of target development and operation

• Experience working in an international environment is essential

• Excellent oral and written English skills are a prerequisite; knowledge of other European languages would be an advantage
