Ion traps play an important role not only in high-precision experiments on stable particles but also on exotic nuclei. Besides accurate mass measurements they have recently been introduced to nuclear decay studies and laser spectroscopy as well as to tailoring the properties of radioactive ion beams. This broad usage of trapping devices at accelerator facilities is based on the manifold advantages of a three-dimensional ion confinement in well controlled fields: First, the extended observation time is only limited by the half-life of the radionuclide of interest, yielding very high precisions for instance for mass measurements. Second, stored ions can be cooled and manipulated in various ways, even polarization and charge breeding of the ions are possible, giving a unique tool in order to prepare otherwise impossible experiments. Third, it is possible to create a backing free source of radioactive nuclei and to collect light particles (e− and e+) very efficiently, reducing a number of uncertainty in classical spectroscopic experiments. The MATS Collaboration proposes an advanced trapping system at the future GSI facility FAIR for high-precision mass measurements and decay studies on short-lived radionuclides. The proposed setup and the planned experimental program will be presented.
