概要 In TEXTOR a Mo limiter has been tested under various conditions of ohmic and NBI heating for about 100 discharges. Maximum power fluxes of 20 MW/m(2) have been loaded onto the Mo limiter without any serious damage which led to maximal surface temperatures of about 2800 K. The Mo-limiter surface was molten two times with a very thin layer of melting. Local spectroscopy shows that Mo is released predominantly by physical sputtering of the low-Z impurities carbon, oxygen and silicon. The impurity deposition rates in the SOL were measured using collector probes showing a ratio of Si/C and Mo/C of typically 6/100 and 0.1-1/100, respectively.
