[en] The objective of this review article is primarily to give an overview of the production of the energetic heavy ions by various particle accelerators in the country and around the world and further to use them for atomic physics experiments. An effort has been made to bring out an exposition of the heavy-ion 15 UD pelletron machine which has been recently installed as a National Facility for the University users at the Nuclear Science Centre (NSC), New Delhi. Possible major research areas aiming to utilize the facility are mentioned. The relevant theoretical models to interpret the processes involved in metallization of atoms or ions are also summarized. A few experimental techniques to study the primary and multiionization processes are illustrated. In addition, some effort has been devoted to give a brief description of the parallel plate avalanche counter (PPAC) and the micro channel plates (MCP) detectors which are very often employed in accelerator based atomic physics experiments.
