Abstracts

EN

Emittance of short-lived nuclide beams produced in hot cavity ion sources is calculated. Influence of half-life period as well as the average sticking time on beam emittance is under investigation. Two different shapes of ionizer cavity are considered: almost fully spherical and hemispherical ones. Changes of beam emittance due to the extraction channel geometry (its diameter and length) are studied. A new concept of scaled efficiency (ion source brightness analogon) is introduced in order to compare the two-ion source configurations. Phase space portraits of the extracted beams are presented.
