Neutronics Scientist

ISIS is a world-leading centre for research in the physical and life sciences at the STFC Rutherford Appleton Laboratory near Oxford in the United Kingdom. Our suite of neutron and muon instruments gives unique insights into the properties of materials on the atomic scale. We support a national and international community of more than 3000 scientists for research into subjects ranging from clean energy and the environment, pharmaceuticals and health care, through to nanotechnology and materials engineering, catalysis and polymers, and on to fundamental studies of materials.

We are looking for a scientist to join the growing ISIS Neutronics Group.  The design of new neutron capabilities at ISIS is underpinned by detailed computer calculations and simulations.  Such new capabilities include, for example, modifications to the ISIS Target Stations’ target and moderator assembly, designs for new neutron instruments or upgrades to existing instruments.  Neutronic calculations are key to the development of the target, moderator assemblies and beam transport elements such as guides and choppers, shielding, instrument detector configurations and final instrument performance.  They allow optimization of components in response to the scientific needs of the research community.  The ISIS neutronics team currently uses standard neutron transport codes, such as MCNPX, together with in-house developed software.
 
This is an area of growth and development within ISIS with key challenges as we continue to develop the ISIS facility and also participate in international projects and collaborations such as the European Spallation Source. The group aims to develop the required work flows and methods to quickly and efficiently tackle the grand challenges in nuclear analysis for spallation facilities.  The group offers the potential for the postholder to develop their own research in radiation transport modelling within the overall objectives of the group.  We are looking for a person to join this growing team who has experience in radiation transport simulation and who would like to join us to continue to develop the application of this technique to modern neutron sources.

About You

•         Play an  important role in the development  of neutronic simulation technique and its application to the work at ISIS encompassing target, moderator, reflector, shielding and instrument developments.

•         Provide support and advice  in neutronic calculations to accelerator and health physics group in the areas of shielding and activation of components.

•         Be responsible for helping to deliver the work of  the neutronics group in a timely and professional manner.

•         Ensure that the neutronics simulations are carried out in a well-documented quality controlled manner.

•         To manage a workload from competing demands.

•         Collaborate with other neutron sources around the world in the area of neutronics.

•         Enable the work of the group to be presented at relevant international conferences and in journal articles

You will report to the Neutronics Group Leader and will need to be team oriented and be able to liaise extensively with other ISIS staff and groups to progress neutronics simulation needs.  There will be opportunities to collaborate with similar groups at other neutron sources, particularly with regard to the development of the European Spallation Source currently under construction.

Personal Skills and Attributes

•         A PhD or equivalent experience in the physical sciences, most likely in an area related to nuclear physics, particle transport simulation or activation.

•         Familiarity with the operation and development of simulation codes for particle transport including knowledge of Monte-Carlo techniques such as variance reduction methods, use of nuclear cross-sections, knowledge of transport codes (MCNPX, FLUKA, GEANT4, etc).

•         A track record in the performance of particle simulations for the development of instrumentation or facilities.

•         Direct experience of simulation relevant to neutron facilities would be an advantage.
