After 40 hour irradiation time, about 7 ci of radioactive isotope 64cu was produced via 63cu ( n, y ) 64cu reaction. after simple disposal, the irradiated copper sample was installed in the high - intesity ion sputter source on the hi - 13 tandem accelerator. then 64cu ions extracted from the high - intesity ion sputter source and injected into the tandem accelerator, 64cu ions can be accelerated to an energy of 80 mev and formed the off - line rnb since natural
