Power deposition measurements have been carried out on the ALT-II toroidal belt pump limiter and the inner bumper limiter in TEXTOR for Ohmic, neutral beam and RF heated discharges. Two infrared cameras and the ALT-II thermocouple array indicate that lamda(E) remains unchanged (7mm) in the presence of beams but increases to 10mm with ICRH. The heating distribution is less uniform on the bumper limiter than on ALT-II, which explains the differences seen in graphite surface pumping.
