Plasma Scenario Modeller

Location: Milton Park, Abingdon, Oxfordshire
Salary: COMPETITIVE
Job type: Full Time, Permanent

The role

Spherical tokamaks (STs) have several beneficial features that make them an attractive option for commercial power production. The compressed shape of STs allows them to simultaneously operate with high self-driven bootstrap current fractions and high betas, the ratio of plasma to magnetic pressure. These features reduce the recirculating power and the required magnetic volume, both of which significantly improve the economics of fusion power. There is also strong evidence that energy confinement is STs has a stronger favourable dependence on toroidal field that observed at conventional aspect ratio. This improved confinement may allow high field ST power plants to be made even more compact.

Tokamak Energy are looking for a plasma physicist to develop and optimise operating scenarios that take full advantage of the favourable properties of high field STs. This role will include: optimising scenarios to improve performance, modelling fully non-inductive scenarios with high bootstrap fractions; modelling the core and edge plasma regions; developing plasma current start-up and ramp-up schemes that are compatible with HTS tokamaks; optimising for improved stability and high performance; and developing predominately RF heated regimes. The role will include modelling for both current and future devices. The successful candidate will also work closely with Tokamak Energy’s collaborators to understand and incorporate results from relevant experiments.

Responsibilities

  • Responsible for Tokamak Energy’s in-house scenario development capabilities
  • Scenario modelling to optimise performance of Tokamak Energy’s current machine, ST40
  • Part of the concept design team for the world’s first HTS high field spherical tokamak, ST-F1

Selection criteria

  • PhD in plasma physics or fusion related field, or equivalent experience
  • Experience modelling tokamak plasmas using transport/equilibrium/stability codes
  • Demonstrated ability to work effectively in a multi-disciplinary team of scientist and engineers
  • Organised approach to overcoming complex challenges

Benefits

  • 25 days holiday, pro rata (plus bank holidays)
  • Company pension scheme
  • Eligible for company share option scheme after 1 years’ service
  • Company bonus scheme, discretionary, dependant on performance
  • Private medical insurance after 3 months service
