Plasma detachment in tokamaks is useful for reducing heat flux to the target. It involves interactions of the plasma with impurities and
neutral particles, leading to significant losses of plasma power, momentum, and particles. Accurate mapping of plasma emissivity
in the divertor and X-point region is essential for assessing the relationship bet…
A prototype infrared video bolometer (IRVB) was succesfully deployed in MAST-U, the first deployment of such a diagnostic in spherical tokamaks. The IRVB was designed to study the radiation around the x-point and has the potential to return emissivity profiles of unprecedented spatial resolution. The system was fully characterised prior installatio…
