摘要：

This paper describes methods used in the manufacturing of chemically reactive targets such as calcium ((nat)Ca), lithium-6 ((6)Li) and molybdenum-97 ((97)Mo) for nuclear physics experiments at the iThemba LABS cyclotron facility (Faure, South Africa). Due to the chemical properties of these materials a suitable and controlled environment was established in order to minimize oxygen contamination of targets. Calcium was prepared by means of vacuum evaporation while lithium was cold rolled to a desired thickness. In the case of molybdenum, the metallic powder was melted under vacuum using an e-gun followed by cold rolling of the metal bead to a desired thickness. In addition, latest developments toward the establishment of a dedicated nuclear physics target laboratory are discussed. (C) 2009 Elsevier B.V. All rights reserved.
