Power exhaust problem is growing in interest as the tokamak power of the foreseen projects ITER, DTT, DEMO increases, achieve the required maturity for the employed technology to face this problem is therefore crucial. Particles escaping plasma confinement bring many consequences to deal with, from erosion of the impinging target, to plasma contamination passing through the very high heat load that needs to be dissipated in the divertor region. To find the optimal choice according to each aspect is not an easy task and a balance of the capability to face them by the different divertor solutions is under study, among these proposals a capillary porous structure (CPS) is envisioned to keep in place a thin film of liquid metal that can be exploited as a primary facing component (PFC) free from radiation damage and able to cope with higher power loads also by mean of his latent heat of evaporation.
