CHIMERA will be the only machine in the world able to test components under the unique combination of conditions encountered in large fusion devices, such as ITER.

It is designed to address the specific engineering challenges associated with fusion and validate complex, bespoke and high-risk manufacturing.


CHIMERA is designed to test metre scale prototype components in an environment representative of a fusion power plant, including those that will be exposed to the harshest conditions, such as the first wall, blanket, divertor and diagnostic systems.

CHIMERA will simultaneously subject components to:

  • High temperatures
  • High heat flux
  • Static and pulsed magnetic loads
  • Thermal cycling, fatigue, creep and other failure modes
  • Under vacuum, air or inert gas

Components will be analysed using optical digital image correlation and laser metrology to map 3D surface deformations and damage. These and other techniques can be used to generate and synchronise component digital twins – predictive models and simulations that will be crucial to the design and qualification of future fusion power plants.
