Trap-based Cluster Research and Cluster-based Investigations of Ion Storage at ClusterTrap.

ClusterTrap is a setup devoted to the investigation of atomic clusters. The Penning trap allows various studies after preceding preparation steps. In particular, the clusters may be size selected and their charge state may be varied by electron impact ionization or electron attachment during storage. On the other hand the clusters can be used for extended studies of the properties of the Penning trap. Both aspects are described with recent examples. © 2006 American Institute of Physics [ABSTRACT FROM AUTHOR]
