An important issue in the development of thermonuclear fusion reactors is the lifetime of the reactor wall. Bombardment by energetic ions and neutral particles from the plasma will lead to continuous erosion of the plasma-facing surface. Actual rate of erosion is governed by varyity of factors, such as surface roughness and angle of incidence. To obtain quantitative data, relevant for future reactor design, we studied sputter yield of Mo and varied surface roughness. In paper we investigated sputtering of Mo with keV deuterium ions in well defined laboratory condition. Findings were supported by 3D Monte-Carlo simulation in SDTrimSP-3D computer code.

Co-workers from the department Mitja Kelemen, Sabina Markelj and Primož Pelicon were working together with co-workers from department of surface engineering (F4), Max-Planck-Institut für Plasmaphysik, Istituto per la Scienza e Tecnologia dei Plasmi CNR, Politecnico di Milano and VTT Technical Research Centre of Finland.
