概要	Ion fluxes in the scrape-off layer (SOL) of the TEXTOR tokamak were traced by means of the collector probe technique during tests of tungsten and molybdenum limiters. Graphite probes were exposed under different operation conditions: limiter position, plasma density, neon edge cooling and heating mode. Following the exposures, the surfaces were examined with ion beam analysis techniques (RBS, NRA) in order to determine deposition rates of metals, deuterium and other species. Under the same experimental conditions deposition rates of tungsten are found to be 6.5-7.5 times lower than those for molybdenum.
