✦ Synopsis

Characterization of a continuous source of single-charged transition-metal cluster ions is reported. Formation and cooling of the clusters occur via vaporization with an 8 kHz Cu vapor laser in a He flow. Cluster ions are mass-selected by a magnetic sector. Clustering and temporal behavior are examined with respect to variation in the length of the clustering region. Al and Fe show ion intensity decreasing monotonically with cluster size. Introduction of oxygen into the He converts iron cluster ions to iron oxide cluster ions.
