The research on the properties of nuclei is major for improving nuclear models. Laser spectroscopy enables studies of nuclear deformation and moments by measuring isotope shifts and hyperfine structures.
The Jet Resonance Ionization Spectroscopy (JetRIS) setup at GSI extends measurements to previously inaccessible nuclides (Z > 100). The ionization in a hypersonic gas jet allows the measurement of atomic transitions of the nuclei. Detecting nuclides via α-decay limits the accessible nuclides. A decay-independent detection scheme will expand this number. For this purpose, JetRIS will be combined with a multiple-reflection time-of-flight mass spectrometer (MR-ToF MS), which will also enhance detection efficiency. A radiofrequency quadrupole cooler buncher is used for the conversion of the continuous ion beam of JetRIS into ion bunches required for the MR-ToF MS.
This contribution will present results from the characterization and optimization of the buncher system.
