Recently commissioned and future RNB facilities

There is a worldwide interest in fundamental and applied scientific research with exotic nuclear beams in order to improve our understanding of the nature of matter and of the evolution of matter in the universe. The nuclear physics working group of the OECD Megascience Forum concluded in 1999 that "A new generation of high-intensity RNB facilities of each of the two basic types, ISOL (Isotope Separator On Line) and In-Flight, should be built on a regional basis. Interested governments are encouraged to undertake the necessary decisions within the next few years, and the facilities themselves should become operational in five to ten years". This interest has led to the design and development of a number of new facilities to increase both the variety and the number of exotic ions. This paper reviews and compares recently commissioned and proposed facilities.
