At GSI-Darmstadt we use the Radiation-Detected Resonance-Ionization Spectroscopy (RADRIS) technique, to study elements in the heavy actinide region to determine their basic nuclear and atomic properties. A setup combining the features of RADRIS with laser spectroscopy in a gas-jet is currently under development to minimize broadening mechanisms occuring in the gas environment of RADRIS, improving the spectral resolution by about an order of magnitude. Due to low production rates in these experiments it is important to minimize the background from other reaction or decay products. In addition, for long-lived nuclides a decay-based detection will not be feasible. With a multi-reflection time-of-flight mass seperator (MR-ToF MS) a separation of ions with different mass to charge ratio can be achieved with a high mass resolving power, suppressing background from unwanted species. For this reason an MR-ToF MS will be added to the gas-jet apparatus. A technical overview oft the MR-ToF MS will be given and its integration into the system will be discussed.
