Abstract
Since 2001, the SPIRAL1 facility has been providing post-accelerated radioactive beams by the ISOL method. Over the last decade, SPIRAL1 has been improved to provide beams of condensable elements, by using a combination of a FEBIAD-type ion source (to produce 1+ ions) and a PHOENIX ECR charge breeder (to transform 1+ ions into N+ ions for post-acceleration). Both these elements have been improved in recent years: the FEBIAD source has been upgraded to improve its efficiency and reliability over time and the charge breeder was modified to extend the range of available charge states. In addition, a krypton beam was recently sent in a FEBIAD target ion-source system (TISS), allowing to produce medium mass radioactive 1+ ions that had not been previously produced in SPIRAL1. This papers compiles recent results illustrating the gain in performances and beam offer at SPIRAL1.
