概要	Limiter experiments with a Mo test limiter have been carried out in TEXTOR under various conditions with ohmic and NBI heating. Maximum power loads reached about 20 MW/m(2) resulting in surface temperatures up to the melting point. A maximum fraction of 8% of the total convective energy in the plasma was deposited onto the Mo limiter. Molybdenum impurities are mainly produced by physical sputtering due to the impact of C and O impurities. Under ohmic heating conditions the Mo impurity radiation increased with increasing plasma density, though the relative source strength of the Mo release decreased. Approaching a critical density of about 3 x 10(13) cm(-3) Mo accumulated in the plasma centre leading to strong central radiation with hollow temperature profiles, which resulted in a minor disruption.
