Abstract

A new multitracer production system, which consists of a gas-jet-coupled multitarget system for short-lived radioactive tracers and a gas- and water-cooled target system for intense beam irradiations, has been installed on a beam line of the K540 MeV RIKEN Ring Cyclotron. The performance of the gas-jet system was investigated with 50 radionuclides of 18 elements produced in the 135 MeV nucl.-1-14N induced reaction on natCu. The gas-jet efficiencies of the nuclides varying from 61Cu to 24Na, except for the chlorine isotopes, show a smooth variation as a function of the mass difference between a product and a target. The multitracers on the natAg and 197Au targets were also produced by the 135 MeV nucl.-1-14N beam with the intensity of 0.7 pμA, which was more than seven times the limit of the previous system.
