Salary: Competitive
Job type: Permanent
Application deadline: 25 September 2020

The role

Tokamak Energy is currently operating the world’s first high field spherical tokamak, ST40; designing and building increasingly powerful high-field HTS magnets; and designing a large scale HTS tokamak, ST-F1, that will demonstrate thermonuclear fusion power production and the viability of our approach at significant scale.  We are seeking a talented scientist to join our physics team and contribute to the design and optimisation of advanced divertors to test in ST40 and adopt in future devices. The role will involve: i) developing and assessing divertor concepts using a range of modelling tools, in particular fluid and kinetic codes to assess first wall loads, detachment, radiation, neutral dynamics and pumping; ii) contributing to ST40 experiments and experimental data analysis; and iii) maintaining and establishing collaborations in the field of plasma exhaust within the fusion community.


  • Assist with the design and assessment of divertors for ST40 and future devices by perform plasma boundary simulations using fluid and neutral modelling tools
  • Contribute to boundary physics experiments on ST40
  • Contribute to experimental data analysis of ST40 divertor diagnostics (e.g. IR camera and Langmuir probes)
  • Report findings at internal meetings, conferences and in peer-reviewed journals
  • Contribute to the development of SOL predictive and interpretive models and codes
  • Coordinate and contribute to relevant collaborations in the field of plasma exhaust
