Abstract

TO TEST ITS APPLICABILITY AS WALL MATERIAL FOR NUCLEAR FUSION EXPERIMENTS, A COPPER BASED BINARY ALLOY CONTAINING 17 AT.% OF LITHIUM HAS BEEN BOMBARDED WITH A MONOENERGETIC MASS-ANALYZED 6 KEV ARGON ION BEAM AT TARGET TEMPERATURES CLOSE TO ROOM TEMPERATURE. THE VELOCITY DISTRIBUTIONS OF BOTH CONSTITUENTS HAVE BEEN MEASURED BY MEANS OF LASER INDUCED FLUORESCENCE. MEAN SURFACE BINDING ENERGIES OF 2.2 EV FOR THE LI COMPONENT AND 2.4 EV FOR THE CU COMPONENT HAVE BEEN DERIVED FROM THE EXPERIMENTAL DATA, COMPARED TO 3.5 EV FOR A PURE COPPER TARGET. A COMPARISON OF THE ENERGIES INDICATES ONLY A MODERATE LITHIUM ENRICHMENT IN THE FIRST FEW ATOMIC SURFACE LAYERS OF THE ALLOY UNDER IRRADIATION. MEAN TRANSPORT VELOCITIES OF THE SPUTTERED PARTICLES HAVE BEEN CALCULATED.
