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.},
