Collinear laser spectroscopy (CLS) is a powerful tool to access nuclear ground state properties of short-lived radionuclides [1]. However, in order to explore the most exotic nuclides far away from stability, more sensitive methods are needed.
For this reason, the novel MIRACLS project at ISOLDE/CERN, aims to combine the high spectral resolution of conventional CLS with high experimental sensitivity. This is achieved by trapping ion bunches in a 30 keV MR-ToF (Multi-Reflection Time of Flight) device, which greatly enhances the observation time and hence, the sensitivity, while retaining the high resolution of CLS.
This presentation will introduce the MIRACLS concept, present the first results from a proof-of-principle experiment and give an outlook to the design of a 30 keV MR-ToF apparatus including a compact, linear Paul trap for optimal beam preparation.
