ISIS Neutronics Group Leader

We require a Leader for the ISIS Neutronics Group to lead the neutronics activity at ISIS.

The design of new neutron capabilities within ISIS is underpinned by detailed computer calculations and simulations.  Such new capabilities include, for example, significant modifications to the ISIS First Target Station target and moderator assembly, designs for new neutron instruments or upgrades to existing instruments. Computer simulations are used in all these cases to predict the behaviour of neutrons as they are created, moderated, transported, manipulated, scattered and detected.  These neutronics calculations underpin the design of targets and reflectors, moderators, beam transport elements such as guides and choppers, instrument detector configurations and final instrument performance.  They allow optimisation of components in response to the scientific needs of the research community.  The ISIS neutronics team currently use the MCNPX neutronics code together with in-house developed software

This is an area of growth and development within ISIS, and we require a person to lead the neutronics group.  The person will need to have significant experience in radiation transport computer modelling and simulation, including activation analysis. 

 

List of Duties / Work Programme / Responsibilities

The postholder will:

•         lead the neutronics activity at ISIS, including developing ISIS work in this area for target, moderator, reflector, shielding and instrument developments.

•         be responsible for the work of a group of neutronics scientists, including line management of the team

•         set priorities for the neutronics work from competing demands

•         ensure that the neutronics simulations are carried out in a well-documented and well-established manner

•         liaise with a wide variety of internal groups regarding neutronics simulations, including engineers, instrument scientists and health physics

•         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

 

Contacts and Communication

The post-holder will report to the Head of the ISIS Diffraction and Materials Division.  They will be the line manager for neutronics team members (currently 3 staff).  They will need to liaise extensively with other ISIS groups to establish neutronics simulation needs, priorities and specifications.  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 in the physical sciences, most likely in an area related to nuclear physics, particle transport, activation.

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

•         A track record in the performance of particle simulations for the development of instrumentation or facilities or for the prediction of radiation activity.  Direct experience of simulation relevant to neutron facilities would be an advantage.

•         Experience of project management and prioritization of group work

•         Line management experience would be an advantage.

  

Any other Relevant Information

This is a permanent post within ISIS.

Some overseas travel will be expected.
