High intensity ion guides and purification techniques for low energy radioactive ion beams

This report gives an overview of the different devices which can be used for the purification of high intensity low energy radioactive ion beams: high resolution magnetic separators (HRS), multi-reflection time-of-flight mass separators (MR-TOF-MS) and Penning traps (PT). An overview of HRS, existing or in development, and the methods to increase the resolving power are presented. The MR-TOF-MS of ISOLTRAP and other projects having been presented during this conference, only the main characteristics of such devices are discussed. Concerning the PT, intensively used to measure masses with high precisions, we will present the PIPERADE project which aims to provide pure beams of exotic nuclei with unprecedent intensities at the future DESIR/SPIRAL2 facility.
