Methods of production of short-lived isotopes at the ISOLDE (isotope separator on-line) mass separator

Abstract

A survey of the target and ion-source techniques used at the ISOLDE (isotope separator on-line) facility for the production of short-lived mass-separated nuclei is given. The production of high-intensity beams of radioactive nuclei by bombardment of thick targets with 600-MeV protons or 910-MeV ³He is discussed. The release properties of various refractory target materials are presented, and the influence of reactive gases and the development of ion sources are considered. Results of on-line tests are given.
