Jf. Roux et al., MASS SELECTION OF NEUTRAL CLUSTERS IN LOW-ENERGY CLUSTER BEAM DEPOSITION EXPERIMENTS - IS IT REALISTIC, Applied physics letters, 64(10), 1994, pp. 1212-1214
The crucial problem in controlling and filtering the size of free neut
ral clusters generated by a cluster source is studied in the particula
r case of the Sattler source type. The present work shows that a veloc
ity selector can be used to control the size of neutral clusters produ
ced in the low-energy cluster beam deposition system. This velocity se
lector is also used to measure the kinetic energy of free Bi clusters.
The experimental results obtained for Bi clusters are compared with p
revious theoretical predictions.
