The LISEL setup (Low-energy Isobar SEparation by Lasers) is currently being built at the University of Jena in the framework of a BMBF funded project. It comprises a gas-filled radio frequency quadrupole cooler where negative ions will be slowed down to thermal energies and overlapped with a laser beam. This allows an elemental selective suppression of isobars by laser photodetachment by careful selection of the photon energy. The tuneable Ti:Sapphire laser system is currently being developed at the University of Mainz. After commissioning the setup LISEL will be transferred to the DREAMS (DREsden AMS) facility at the Helmholtz Center Dresden Rossendorf (HZDR).
To get the required spectroscopic data especially for negative molecular ions a measurement program is currently being established at the low-energy electrostatic storage ring FLSR at the University of Frankfurt. This allows to study vibrationally cold molecules and acquire photodetachment data to establish further suppression schemes. This allows to study currently unavailable new isotopes and extends AMS to many new applications.
