Formation of layers deposited in remote areas of TEXTOR are discussed in detail. Their composition, thickness and optical properties were examined. These deposits form soft, semitransparent films consisting mainly of carbon, hydrogen and deuterium. The content of hydrogenic species depends on temperature of the location, where the deposit had grown. The D/C fraction varies between similar to 0.07 at the hot part of the duct inside the vacuum vessel and similar to 0.7 in cold sections of the pump duct. The mean deposition rate of carbon in the pump ducts was similar to 1 x 10(21) C/h; which corresponds to about 0.1% of carbon eroded from the blades of the poloidal belt limiter. Despite the low deposition rate of carbon and, consequently, als...
