Description
SPES is an INFN project supported by two Italian national laboratories, Laboratori Nazionali di Legnaro (LNL, Legnaro, Padova) and Laboratori Nazionali del Sud LNS, Catania), and is currently under way at LNL. Aim of this project is the production, ionization and post-acceleration of radioactive ions to perform forefront research in nuclear physics. To this scope, the project chose an ECR-based charge breeding technique: in particular, an upgraded version of the Phoenix booster, developed by LPSC of Grenoble in 2014 and successfully tested in March 2015. The SPES- Charge Breeder (SPES-CB) took advantage of the latest upgrades of this device, like the optimization of the axial position of the two iron rings surrounding the hexapole, carried out during the EMILIE Project. Other improvements derived from the experience on charge breeding made at INFN or from special needs of the SPES project. The SPES-CB will be equipped with a complete test bench, totally integrated with the SPES beam line, and a specially designed Medium Resolution Mass Spectrometer (MRMS), in order to limit beam contaminations induced by the breeding stage. This contribution will describe the main technological aspects of the SPES-CB and its beam line, together with the first results obtained during the acceptance tests. The presentation will show also the results of the work, carried out by the INFN in the framework of the EMILIE project, on the numerical simulation of the 1+ beam capture by the plasma of the charge breeder, evidencing the very good agreement between numerical and experimental results for both heavy and light ions.
