| Outline of Final Research Achievements |
In this research project, new concepts towards microscopic multipole traps have been investigated and several possibilities have been tested in the experiment. We accomplished several tests of small trapping systems as used for extraction of ions from a gas-catcher cell. Experience has also been obtained for the cryogenic operation of a previously existing Paul trap during various on-line experiments over the period of the grant.
The final goal of an independent microscopic multipole trap coupled to a mass spectrometer is further pending, but can be accomplished using the existing devices. By the experience obtained up to date, planar trap designs (i.e. printed electrodes on an insulating board) are most promising for the realization of the trapping structures. Trapping systems with smaller volumes are necessary and can be realized by more narrow electrode boundaries, so that the motional space of the ions is restricted to enable a meaningful combination with a mass spectrometer.

| Academic Significance and Societal Importance of the Research Achievements |
Nuclear isomers separated by their mass offer unique opportunities to precisely study masses of superheavy elements on the search for the island of stability. This research project is focused on the realization of very high resolving powers of fast mass spectrometers to enable isomeric resolution.
