The WEST tokamak has just installed an actively cooled tungsten divertor as its main plasma-facing component, based on technology similar to that of ITER. This very important milestone was reached thanks to a collective and collaborative effort. It paves the way for WEST operation over long periods (up to 1000s) with high levels of heat flux (> 10 megawatts per square meter). This allows WEST to test these components against ITER-type plasma in a tokamak environment.
Interactions between the plasma and the walls of tokamak fusion facilities can generate dust from materials exposed to the plasma. This dust can interfere with
