The Machine Directorate at the European Spallation Source (ESS) in Lund, Sweden, invites applications for a Group Leader for ESS Spallation Physics position in the Target Division.

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 new central group for Spallation Physics will have duties across all ESS site including:

  • Neutronics – Monte Carlo transport calculations and activation calculations.
  • Computer tools and cross-section development.
  • Experimental verifications & developments
  • Spallation materials properties and fluid dynamics of interest for the operation and upgrade of the facility.
  • Interface to the neutron scattering instrument teams
  • Shielding calculations (and waste characterization & classification)

Description of main responsibilities

The Group Leader for ESS Spallation Physics will have the following responsibilities:

  • Line management responsibilities; lead, plan and coordinate the work within the group, recruit and retain competent and motivated personnel with target physics expertise, promote a well-functioning work environment etc
  • The full spectrum of physical processes and their interconnections for spallation source target station design, construction and operation, with particular emphasis on the holistic analysis of target configuration for optimal performance, safety, availability, maintainability, environmental friendliness and cost efficiency
  • Data collection, research and development of research on the physical processes and interactions in spallation target stations: target, structural parts, reflector, containers, vacuum vessels, pipes, utilities
  • The full spectrum of materials issues for spallation source target station design
  • Data collection, research and development of research on engineering design aspects of materials for various functions in the target station: target, structural parts, reflector, containers, vacuum vessels, pipes, utilities
  • Safety and aging of materials in the radiation conditions of spallation, review and application of standards and qualified materials data, extension of qualification of materials of special interest for spallation, when applicable
  • Conceptual, functional and detailed engineering design of an irradiation plug for material testing at the ESS target station
  • Leading participation in the conceptual, functional and engineering design for the holistic optimization of the ESS target station configuration
  • Interface with other areas of activities in the Target Division and other ESS divisions
  • Organizational, management and reporting responsibilities for special and general tasks assigned within the Target Division in the framework of various ESS projects
  • Compilation, documentation and dissemination of the results of in technical reports, scientific publications and at professional meetings
  • Interaction with experts in other similar facilities, academic institutions and industry in order to maintain a world class expertise in target physics at ESS
  • Guiding and supervising the work of collaborators in the Target Physics Group, responsibility for safety, quality, compliance, internal and external coordination
  • Training young group members in physics research, development and engineering
  • Budget planning

The responsibilities in all these areas concern all phases of the ESS project: conceptual design, engineering design, research and development in preparation to build, construction, commissioning, operation and maintenance.

Qualifications

To be successful in this role, we expect the candidate to have the following skill set and experiences;

  • Proven leadership skills: As a line manager and coordinator of the work it is crucial that you have excellent leadership skills and extensive expertise in people management and team building management.
