摘要
Production efficiencies of radioactive oxygen and nitrogen beams for the SPIRAL target-source system, measured at GANIL on the SIRa test bench, are presented. From the overall efficiency of oxygen, the product between the efficiency of transformation of O into CO and the effusion of CO from the target to the ion source, was deduced. The production yield measurements of oxygen and nitrogen isotopes performed on the SIRa test bench and those of fluorine directly measured on the SPIRAL facility are presented.
