The applications of very precise mass measurements (δm/m ≤ 10−8) on exotic short-lived nuclei have opened up an attractive research realm which will be present also at the future international facility FAIR (Facility for Antiprotons and Ion Research) with MATS. The MATS Penning trap facility comprises several key elements: a Radio Frequency Quadrupole (RFQ) buncher for beam preparation, an Electron Beam Ion Trap (EBIT) for charge breeding, and two Penning trap systems, one for preparation and spectroscopy and one for mass measurements. The conceptual design of these elements is almost ready. One feature of the MATS facility will be the manipulation of highly charged ions and the monitoring of their cooling process using a novel cryogenic broad-band Fourier Transform-Ion Cyclotron Resonance (FT-ICR) detection system. A prototype of this system is currently under commissioning at the Max-Planck-Institute for Nuclear Physics in Heidelberg. It will be used at first in the beam line of the Karlsruhe Tritium Neutrino experiment (KATRIN). In this contribution the layout of the MATS facility will be presented underlining the recent highlights obtained with this novel FT-ICR system.
