Abstract

The problem of increasing the mean size of clusters in gas-jet targets is tackled. Based on a mathematical model of clustering, the dependence of the cluster mean size on the nozzle length and rate of expansion is derived. The nozzle shape providing micrometer-size clusters is found. The parameters of gas-jet targets produced with this nozzle are studied in detail.
