The CSRe internal target has two operation modes: polarized mode and unpolarized mode. The unpolarized target is a cluster target. The clusters are produced during the expansion of the gas in the supersonic part of the nozzle. The cluster beam is formed while passing a set of the skimmers, giving an intense beam with a well-bounded intensity profile. To get the good clusterization it’s necessary to keep the temperature of
