A study of the different operation modes of a sputtering gas-aggregation source is presented. The size distributions of small cobalt clusters shed some light on the first steps of the growth process. Large clusters of 2 to 6 nm diameter with narrow distributions are obtained. Their icosahedral structure is identified by HRTEM observations.
