      abstract     = {In this paper we report on the present status and future
                      plans of polarized beams in the COSY synchrotron ring. COSY
                      is a synchrotron ring in the momentum range from 295 to 3700
                      MeV/c. Polarized deuterons and protons are routinely
                      delivered to exp eriments over the whole momentum range. No
                      depolarization occurs during the acceleration of deuterons
                      in COSY. For polarized protons many depolarizing resonances
                      are crossed without polarization loss. At imperfection
                      resonances, vertical steerer magnets a re used to increase
                      the resonance strength, leading to a complete polarization
                      reversal. At intrinsic resonances a fast tune jump
                      quadrupole is used to quickly cross the resonances without
                      loss of polarization. Typical proton polarizations are close
                      to 0. 8 below 2.1 GeV/c and about 0.6 for higher momenta.
                      During recent operation an induced depolarizing resonance
                      was used for accurate determination of the relative momentum
                      spread dp/p of the stored beam yielding an accuracy of
                      better than 10(-')(4). For sp in filter studies of the PAX
                      collaboration a low beta target section was installed in
                      2009 and was successfully put into operation early 2010. An
                      upgrade of the EDDA polarimeter electronics and data
                      acquisition system is underway to ensure continued avail
                      ability of the polarimeter, which is essential for the
                      polarized proton operation of COSY. In the near future it is
                      planned to install a Siberian snake solenoid of 4.5 Tm to be
                      able to provide in addition to vertically polarized protons,
                      longitudinal pola rization as well. This solenoid will allow
                      the preparation of a longitudinally polarized beam up to a
                      kinetic energy of 500 MeV.},
