THE GENERATION OF RADIOACTIVE ION-BEAMS

A new design is presented of an ion source of the hollow-cathode type adapted to the on-line isotope separator JASNAPP-2 at JINR, Dubna. To determine its optimal work conditions the source characteristics have been investigated. With the source were generated radioactive fluxes o f various isotopes of Po, At, Ri, Pb, Pr and Rn using a 660 MeV proton beam and the Th (p, xpn) reaction. The relative values of the cross-s ections for production of the above isotopes are also given. Copyright (C) 1996 Published by Elsevier Science Ltd
