The tokamak WEST (Tungsten Environment in Steady-State Tokamak) will start operating by the end of 2016 as a test bed for the ITER divertor components in long pulse operation. In this context, radiative cooling of heavy impurities like tungsten (W) in the Soft X-ray (SXR) range [0.1 keV; 15 keV] is a critical issue for the plasma core performances . Thus reliable tools are required to monitor the local impurity density and avoid W accumulation.
