Abstract :
Radioactive isotopes produced by the in-flight method are converted into low-energy ions with a thermal ionizer (TI) ion catcher, the operation of which is based on a hot cavity ion source. The extraction efficiency of the TI for different alkali and alkali-earth elements has been studied and compared to a model based on diffusion only. The model describes the stationary limit, i.e. the extraction efficiency, as well as the dynamic response of the TI output when the primary beam is switched on and off.
