S3-LEB and JetRIS: a collaboration around laser spectroscopy and ions manipulation

by Alexandre Brizard, 1st year PhD student at GANIL/GSI

The Super Separator Spectrometer (S3) will soon produce beams of exotic nuclei we long to study. Exotic because of their high number of nucleons, their quantum “magical” stability, or their newly studied ways to decay, we need tools to extract the information we want from this beam we will get. The Low Energy Branch is one of these tools.

S3-LEB will practice laser spectroscopy on these nuclei to reach knowledge on their shape and the way the nucleons are organised in it. This method will also be used to extract specific nuclei for further measurements as for their mass or their decay. The setup is rather new in Ganil, but fortunately our team can count on many collaborators around the world, with experience on the different sections of this Low Energy Branch.

Among these collaborators, GSI in Germany has two laser spectroscopy setups which are very similar to S3-LEB: RADRIS and JetRIS. In this presentation I will explain more about the operation of S3-LEB and its similarities and differences with its German cousins. I will then introduce my work on how to produce bunches of ions that are needed in both S3-LEB and JetRIS.
