Plasma Edge Model Developer
FTA 2 years FT
£32,993 TO £50,272 pa (including MPP) + excellent benefits including outstanding pension scheme
4th April 2019
Do you have significant experience of developing scientific codes and optimising the algorithms to fully exploit HPC, or are you an experienced plasma edge modeller? Would you be passionate about applying your expertise to improve the availability of high-quality simulations that can be exploited to help solve major challenges that face nuclear fusion research?
The UK Atomic Energy Authority has an excellent opportunity for a plasma edge model developer to join their team within the Integrated Scenarios and Transport Unit (ISTU) of the Tokamak Science Department. ISTU is responsible for maintaining and developing plasma modelling software for the JET experiment, and for delivering plasma modelling to help guide JET towards high performance fusion plasmas. JET is in an exciting period in its history, preparing for world-first fusion experiments with D-T plasmas in its ITER-like wall configuration. Optimisation of performance in these experiments requires sophisticated plasma simulations to model heat, particle and momentum transport and how the edge plasma interacts with the tungsten and beryllium wall.
The post-holder will contribute to the ISTU`s modelling activity by:
- developing new algorithms and physics modules both for the 2D multifluid plasma edge code EDGE2D, and for the kinetic neutral particle Monte-Carlo code EIRENE.
- developing parallel algorithms to exploit advanced computers more effectively in the increasingly demanding calculations needed for JET.
- supporting and maintaining the codes.
- developing and maintaining interfaces between EDGE2D, EIRENE and the core transport code JETTO, and adapting these interfaces to exploit ITER`s integrated modelling framework (IMAS).
- delivering edge plasma simulations on request in support of the JET experiment
- supporting scientific users of the EDGE2D-EIRENE code package
While the post-holder`s main priorities are to develop tools and support users, opportunities may arise to exploit edge modelling tools to contribute to JET science. The ISTU team supports a range of additional plasma modelling tools: e.g. for equilibrium reconstruction, inter-shot data analysis, and modelling core transport. If a need arises, the post-holder may be requested to apply their skills (where appropriate) to assisting with the support and development of these other codes.
This post will be offered as a two-year fixed term appointment (with possible transition to a permanent contract at the end of the term).
The appointment will be made either at Level 4 or Level 5 depending on the expertise and experience of the successful applicant. We encourage and welcome applications at either Level; the relevant criteria for each Level are specified in the corresponding Job Descriptions in the application pack. The position will attract a salary in the range £32,993-£37,069 (at Level 4 including MPP) or £44,959-£50,272 (at Level 5 including MPP), and industry leading benefits that include an outstanding pension scheme.
The UK ATOMIC ENERGY AUTHORITY hosts and manages the JET nuclear fusion energy experiment on behalf of the EU and is also home to the UK`s MAST-U fusion energy experiment. UK ATOMIC ENERGY AUTHORITY also works with industry and other third parties to develop new technologies currently in Remote Handling and Materials research. Following recent UK funding two new centres of excellence in tritium fuel handling and component testing and validation are being built. The culture at UK ATOMIC ENERGY AUTHORITY promotes research, innovation and leading-edge technological excellence, whilst investing in its people.
