Scientific Positions in Plasma Physics

The UK Atomic Energy Authority has scientific positions available on its Spherical Tokamak for Energy Production (STEP) programme

  • Closing date: 31 Jan 2021
  • United Kingdom | UK Atomic Energy Authority
  • Date posted: 18 Dec 2020
  • Job type: Government/Public sector
  • Discipline: Plasma science & technology 

If you are a plasma physicist and want to be part of an exciting programme that aims to demonstrate fusion as a net-zero carbon energy source, we need you!

Do you want to work at the forefront of research and technology, solving one of humanity’s biggest problems?

Do you want to be part of a unique international environment?

Come and join us on the Spherical Tokamak for Energy Production (STEP) programme, an exciting and ambitious national endeavour, working in a vibrant team in conjunction with industry to deliver a multi £bn prototype fusion energy plant by the early 2040s. Successful delivery of the prototype will pave the way for a commercial fleet of fusion reactors.

STEP is funded by the UK government for an initial five-year phase, through to 2024, and our key objective is to define a concept tokamak design in that timeframe. To help us achieve this aim, we are now seeking to recruit physicists to work in the following areas of tokamak plasma modelling:

  • Gyrokinetic simulations of core plasma turbulence (two positions).
  • Fast particle physics.
  • Plasma disruptions.
  • Runaway electron physics.
  • Radiofrequency (RF) physics.

While each of these positions will be primarily focussed on plasma modelling in the high beta burning plasma domain of STEP, successful candidates will also work on plasma modelling and experiments in other tokamak devices at Culham and internationally. UKAEA operates the new MAST-U spherical tokamak, one of the two largest spherical tokamaks in the world, which will help to develop the physics basis for STEP. UKAEA also operates JET, the world’s largest tokamak, and is strongly involved in ITER and the European fusion programme. Further details of the STEP project can be found at and more information about UKAEA’s wider work is available here:

In all cases applicants should hold, or be about to hold, a PhD in plasma physics or possess equivalent experience
