Abstract: | AES studies of argon ion induced desorption of carbon from tantalum were performed. The carbon adlayer was allowed to adsorb from a well characterized residual gas atmosphere, that was unvarying within 20%. The argon ions impact on the surface at an angle of 60° from the surface normal with energies between 0.2 to 1.0 keV. The total desorption cross section values measured under these conditions are 0.07–1.1 × 10?15 cm2. |
