      abstract     = {A fast tune measurement is developed for the Cooler
                      Synchrotron COSY at the Institut für Kernphysik of
                      Forschungszentrum Jülich. Betatron oscillations of the beam
                      are excited with a band-limited RF signal via a stripline
                      kicker. Resonant transverse oscillations are then observed
                      using capacitive beam position monitors. Based on the
                      bunch-by-bunch beam position data the betatron tune is
                      determined. The usage of bunch-by-bunch data is
                      characteristic of the new system. It allows for a discrete
                      tune measurement within a few milliseconds, as well as
                      continuous tune monitoring during beam acceleration. The
                      high precision tune measurement also enables determination
                      of the beam chromaticity. Therefore, the beam momentum is
                      varied by means of the RF frequency and the subsequent tune
                      change is determined. For routine use during beam operation
                      and experiments, the developed method is integrated into the
                      control system.},
