Status of the MLLTRAP system [*] — •Christine Weber, Robert Meissner, Peter Müller, and Peter Thirolf — Fakultät für Physik, LMU - München, 85748 Garching

The MLLTRAP Penning trap system serves as a development environment, both for mass spectrometry as well as for decay spectroscopy experiments [1] at Europe’s upcoming facilities for low-energy experiments with exotic isotopes. High-precision mass spectrometry in a Penning trap is carried out via a determination of a stored ion’s cyclotron frequency. These experiments are planned at the future DESIR facility of SPIRAL2 in France [2].

A novel detector-trap system is presently being built for the realization of direct in-situ decay spectroscopy experiments of stored ions at MATS [3] at FAIR. This setup combines the high-resolution purification capabilities of a Penning trap with a customized detector-trap. It serves for the ion storage as well as for the detection of the emitted decay products. In this way, novel types of nuclear decay spectroscopy experiments are becoming feasible, which are free from any background or scattering effects from a source material. This contribution gives an outline on the future perspectives of MLLTRAP and the present status of the development work.
