A multicusp ion source for radioactive ion beams

In order to produce a radioactive ion beam of /sup 14/O/sup +/, a 10 cm-diameter, 13.56 MHz radio frequency (RF) driven multicusp ion source is now being developed at Lawrence Berkeley National Laboratory. In this paper we describe the ion source performance with respect to its capability as an ion source for radioactive ion beam (RIB) production using Ar, Xe and a 90% Ar/10% CO gas mixture. In addition ion optic simulations for the radioactive beam line leading to the design of the ion beam extraction/transport system for the actual experimental setup will be discussed.
