First ECR-ionized noble gas radioisotopes at ISOLDE Original Research Article

This paper describes a standard ISOLDE target unit equipped with a MINIMONO ECRIS ion-source. The ion-source has been tested off-line and equipped with a CaO target for on-line tests. Valuable information was gained about high current (100-500 μA) transport through the ISOLDE mass separators designed for <10 μA. The yields and release curves of several light gaseous elements produced via irradiation by 1.4 GeV protons of the CaO target are presented and compared with those obtained under similar conditions with a plasma ion-source.
