Fission yield studies with SPIG-equipped IGISOL : a novel method for nuclear data measurements

2010

This thesis work consists of two sections. In the first section, the development of a so-called Laser Ion Source Trap (LIST) device is described. The LIST device is based on a double SPIG (SextuPole Ion Guide) system, providing the possibility to improve the elemental selectivity of the IGISOL method via highly discriminative laser ionization occurring outside the ion guide. The improved selectivity enables the production of isotopically pure beams. The double SPIG can be used without laser ionization and replaces the conventional skimmer electrode. In this work, the SPIG is compared to the skimmer and is shown to remarkably improve both the efficiency and beam quality of the IGISOL facilit…
