Abstract
A novel type of experimental setup, dedicated to in-trap decay spectroscopy in a Penning trap, is presently being developed at the double Penning-trap facility MLLTRAP, installed at the Maier-Leibnitz Laboratory in Garching. This new tool for α and electron decay spectroscopy is envisaged to be implemented in the future MATS facility at FAIR. It combines the high-resolution mass-purification capabilities of a first Penning trap with a customized ‘detector-trap’ setup, consisting of an arrangement of position-sensitive silicon (Si)-strip detectors that replaces the conventional ring electrode of the trap, providing both, ion storage and detection of decay products. In this way, decay-spectroscopy experiments of mass-selected nuclides, trapped as a carrier-free source, thus avoiding any background or scattering effects, will become feasible via direct in situ spectroscopy of stored ions.
