Post doc for simulation of neutron scattering experiments

The Niels Bohr Institute at University of Copenhagen is offering a post doc position in Monte-Carlo simulations of neutron scattering instruments and experiments, commencing on 01.06.2017 or as soon as possible thereafter.


Description of the scientific environment

The neutron- and X-ray scattering (NSX) group at the Niels Bohr Institute presently contains around 50 professors, post docs, and students. The group is involved in a wide scope of research activities, including instrument construction for the European Spallation Source (ESS) and the School and Workshop part of the Nordic Neutron Science Programme (NNSP).

Project description

This project is composed of three parts, with the common theme of simulation of neutron scattering experiments and instruments. All simulation work will be based upon the McStas software co-authored by this group, and by the McStas extensions for guide simulation (guide_bot) and for simulating realistic multiple scattering (Union). The three parts of the project are:

  • Extending the simulations of multiple scattering by Union to include all main types of neutron scattering (powder and crystal diffraction, small-angle scattering, reflectivity, and inelastic scattering from diffusion and quasiparticles). With this tool, virtual experiments will be set up to provide examples for the teaching at the NNSP Schools and workshops.
  • Development of virtual experiment simulations and corresponding exercises/teaching material taylored for e-learning at the portal.
  • Optimization of the guide for the ESS backscattering instrument MIRACLES on preparation for final approval of the instrument layout. This work will be carried out in collaboration between the NXS group at the NBI and ESS-Bilbao.Project leaders are:
  • Kim Lefmann,
  • Linda Udby,
  • Heloisa Bordallo,

Job description

The position is available for about 1.5 years, depending upon available funding. Your key tasks as a post doc:

  • Expand the capabilities in McStas and Union to expand the capability for simulating neutron scattering experiments
  • Assist teachers in the NNSP courses and workshop to set up virtual experiments using the tools developed
  • Development of virtual experiment simulations and corresponding exercises/teaching material taylored for e-learning at the portal.
  • User-support of McStas Union
  • Optimize the guide for the neutron backscattering spectrometer MIRACLES, currently in the stage of final design.
  • Write scientific articles
  • Teach and disseminate your research, e.g. in connection to the NNSP School and workshops

Formal requirements

Applicants should hold a Ph.D. degree in Physics or equivalent with good results and good English skills and have experience with X-ray and/or neutron scattering. The ideal candidate will be proficient in the McStas simulation tool and its extensions guide_bot and Union and have good programming skills. As criteria for the assessment of your qualifications emphasis will also be laid on previous publications and relevant work experience.
