Lund, Sweden

The European Spallation Source is seeking a Lead Scientist on Centralised Polarisation System for Neutron Scattering Instruments.

The Instrument Technologies Division is part of the Science Directorate, which executes the Neutron Scattering Systems (NSS) project. The NSS scope is to design, build and commission neutron scattering instruments, and the Instrument Technologies Division, together with its in-kind partners, is dedicated to providing and supporting key components not only during construction but also during operation of the facility’s scientific instruments.

The expected high brightness of ESS is ideally suited to using polarised beams and polarisation analysis on the neutron scattering instruments, which are currently being designed and built by partners involving the majority of neutron scattering facilities in Europe. The use of polarised beams and polarisation analysis allows the unambiguous separation of structural, magnetic and incoherent scattering contributions, which has applications throughout biology, soft matter, chemistry and condensed matter physics taking advantage of the inherent strengths of neutrons in being able to see hydrogen atoms and investigate magnetism in novel materials. Whereas the scientific capabilities of many of the first 15 neutron instruments would benefit from polarisation of incident beams and polarisation analysis of scattered beams, few have this in their current scope of construction. ESS will provide polarisation and polarisation analysis capabilities to the instruments via a central service through the Instrument Technologies Division.
The successful candidate will initially report directly to the Head of the Division but work closely with other scientists and engineers within the Directorate. She/he will need to define the scope and detailed project plan, which will deliver a centralised polarisation system for the neutron scattering instruments by December 2023. She/he will be setting up and executing the project, which will require to liaise with instruments construction teams, ESS Scientific and Technical Advisory Panels and other stakeholders to ensure that technical solutions fulfil not only long-term availability and reliability criteria for systems, sub-systems and components but equally so the high-level scientific requirements of the neutron scattering instruments.
Once the Directorate starts operating the instruments it is foreseen to transfer the position into one of the technical groups within the division to provide support and technical assistance during the operation of instruments.

The successful candidate will need to
• lead in the definition of requirements and technical specifications for polarisation systems based on high-level scientific requirements
• participate in the development of strategies, techniques and methods to ensure optimised systems in performance, reliability and cost
• support in-kind partners in the design and procurement of prototype systems for management of polarisation devices
• support in-kind partners and/or commercial suppliers during testing and installation of systems
• commission a centralised polarisation system on site
• ensure safe operation, performance and maintainability of systems
• support the User Programme during facility operation and maintenance during shutdown periods

We are looking for a self-motivated person with a PhD degree in one of the natural sciences with Physics being preferred, as well as 5+ years of work experience, preferably at a facility similar to ESS.
Additional skills and competencies would include:
• Being precise, attentive to detail, striving for the upmost quality, always looking to refine methods and techniques to improve the deliverable
• Being able to multi-task and to work to deadlines
• Having experience leading and managing a team of people with different competencies
The candidate should be able to demonstrate experience in:
• Developing scientific requirements of system with due consideration of scientific requirements of neutron scattering instruments
• Developing scope, budget, schedule and associated risks description that will allow project execution
• Participation in development of complex mechanical systems and assemblies
• Manufacturing considerations in the context of prototype developments incl quality assurance
Additional experience would include:
• Track record of project management
• Experience in stakeholder involvement and stakeholder’s expectation management
• Experience of working in an international environment
Excellent oral and written English skills are a prerequisite; knowledge of other European languages would be an advantage.

Duration & Location

The position is permanent with six months probation period. The position is to be filled as soon as possible. Your work place will be situated in Lund, Sweden.

Massachusetts Institute of Technology
Nuclear Reactor Laboratory

Molten salts are widely used for electrical and thermal energy storage, materials processing, and in Generation-IV Molten-Salt Fission Reactors (MSR) and future fusion reactors (ARC) as a coolant and/or fuel. In particular, the MSR application requires detailed knowledge of the molten salt properties in order to understand and predict the salt’s behavior in service. Fundamental properties of interest include molecular structure and speciation, as well as dynamic properties such as diffusion coefficients for the salt and corrosion and fission products dissolved in it. Computer modeling is necessary to predict changes in physical and chemical properties due to irradiation and burning of dissolved fuel. Our group will perform ab initio molecular dynamics simulations to understand the multi-component liquid solution. Machine learning algorithms will be used to develop a fast-acting model that can handle molten salt with an arbitrary number of chemical elements and be able to predict chemical potential as a function of composition and temperature. The measurement data for the modeling will be obtained with the help of advanced neutron and x-ray scattering and spectroscopy, which provide the most reliable and direct determination of the structure and dynamics of the melts.

The MIT Nuclear Reactor Laboratory (MIT-NRL) is an interdepartmental center that operates a high performance 6 MW nuclear research reactor known as the MITR. It is the second largest university research reactor in the U.S. and the only one located on the campus of a major research university. During its long and distinguished history, the NRL has supported educational training and cutting-edge research in the areas of nuclear fission engineering, material science, radiation effects in biology and medicine, neutron physics, geochemistry, and environmental studies.

It is the only university research facility in the U.S. where students can be directly involved in the development and implementation of nuclear engineering experimental programs with neutron flux levels comparable to power reactors. The MITR is an indispensable resource for developing the workforce for the future of nuclear power.

The MITR is equipped with experimental facilities available to users both within and outside MIT. The NRL staff provides technical assistance for research projects for high school students, undergraduate and graduate students, university researchers and faculty members, and national laboratory users.

The Energy Frontier Research Center (EFRC) on Molten Salts in an Extreme Environment (MSEE) was recently funded at BNL. Liquid molten salts (MS) are found as solvents of the fuel constituents and/or coolants in nuclear reactor technology. Due to their nature as ionic fluids, MS have structural and dynamical correlations distinct from those of uncharged molecular or atomic liquids. The scientific mission of MSEE is to provide fundamental atomic-level understanding of bulk and interfacial molten salts. The Center will measure and predict the local and intermediate-range interactions, the structures and dynamics of molten salts in the bulk and at interfaces. Specifically, the Center will develop and use in situ synchrotron x-ray spectroscopy, scattering and imaging techniques to understand interfacial and corrosion processes in MSEE. X-ray measurements will be integrated with modeling approaches i) to provide fundamental new information on surface ordering and dynamics of MS and ii) to understand and predict non-equilibrium, metastable states formed during the reactions at interfaces.
