A team of researchers led by Professor Kilian Singer, head of the project at Mainz University and now Professor at the University of Kassel, used a Paul trap
to capture a single electrically charged calcium atom.
The 16 papers discuss such aspects as the isotope-selective manipulation of ions in a Paul trap
, the creation and dynamics of topological defects in ion Coulomb crystals, coherent manipulations in a microfabricated ion trap, the high-resolution fluorescence and absorption imaging of single trapped ions, monitoring single quantum systems by unsharp measurements, and ion-atom hybrid systems.
Gunter Werth had to set a Paul trap
as used in Mainz in India, where it was combined with a magneto-optic trap.

The quadrupole shift is likely to be the most difficult to evaluate in a frequency standard and may have a magnitude of about 1 Hz for a single ion in a Paul trap
The so-called Paul trap
and its cousin, the Penning trap, play an important role in modern spectroscopy.
