Carbon cluster diagnostics-II: ExB velocity filter for large carbon   clusters
  An ExB velocity filter is described that has been used for the detection and diagnostics of large carbon clusters Cm (where m is up to ten thousand). The velocity and momentum analyses are compared for our special experimental arrangement. We describe the variability of the resolving power of our compact velocity filter as the main advantage over other comparable mass analysis techniques.
