Company Description

By 2050, the planet could be using twice as much electricity as today. Are you interested in contributing and helping to shape the future of the world’s energy? If so, read on.

Fusion, the process that powers the Sun and stars, is one of the most promising options for generating the cleaner, carbon-free energy that our world badly needs. UKAEA are at the forefront of realising energy from fusion, working with industry and research partners to deliver the ground-breaking developments that will underpin tomorrow's fusion power stations with the aim of bringing fusion electricity to the grid.

Who are we looking for?

We are seeking to recruit a physicist to develop and exploit computational and analytical models describing the behaviour of radio-frequency waves in STEP, MAST-U, and other tokamaks funded by EUROfusion.

It is an exciting time for UKAEA as we have established a national programme aimed at exploring the options, challenges and solutions for accelerating the delivery of fusion power: the Spherical Tokamak for Energy Production (STEP). The plasma current in such devices must be driven in part externally, and radio-frequency waves in the electron cyclotron range of frequencies provide a possible method of achieving this. To investigate the viability of this type of current drive method in STEP, a radio-frequency heating and current drive system is being designed for use on the MAST Upgrade (MAST-U) spherical tokamak.

Job Description

What will you be responsible for?

Depending on your level of experience, your key responsibilities will include:

  • Planning, coordinating and performing work on the modelling of radio-frequency waves and their effects on electrons in tokamak plasma, implementing research strategy in this area.
  • Contributing to the development of codes describing the propagation, mode conversion and damping of radio-frequency waves in tokamak plasmas, together with the effects of these waves on electron populations.
  • Using existing and/or upgraded codes to model the propagation, mode conversion and damping of radio-frequency waves in tokamak plasmas.
  • Modelling heating and current drive resulting from the launch of radio-frequency waves into tokamak plasmas.
  • Contributing to and help to formulate heating and current drive elements of the research programmes on MAST-U, other tokamaks funded by EUROfusion and STEP, implementing research strategy in these areas.
  • Reporting results at science and other regular progress meetings.
  • Disseminating results through conferences and peer-reviewed journal papers

Qualifications

Essential skills, experience and competence required

  • Hold, or be about to hold, a PhD in plasma physics or possess equivalent experience.
  • Proficiency with programming languages, e.g. FORTRAN, C, IDL, Python, Matlab.
  • Proven ability to conduct independent research.
  • The post-holder must be a good team-player with an outward-facing work ethos as they will work closely with scientists around the world.
  • Good oral and written communications skills

Desirable skills, experience and competence

  • Post-doctoral research experience in the modelling of radio-frequency heating and current drive in tokamak plasmas.
  • Experience in designing and exploiting microwave heating and current drive systems for magnetic fusion devices.
  • Strong record of publications in a closely related field.
