Status and Future Plans of the Cooler Synchrotron COSY — •Bernd Lorentz, Ulf Bechstedt, Juergen Dietrich, Ralf Gebel, Andreas Lehrach, Rudolf Maier, Dieter Prasuhn, Alexander Schnase, Herbert Schneider, Rolf Stassen, Hans Stockhorst, and Raimund Toelle — Forschungszentrum Juelich, Germany

The cooler synchrotron COSY delivers unpolarized and polarized protons and deuterons in the momentum range between 600 MeV/c to 3.65 GeV/c to internal and external experiments. To provide high quality beams, an Electron Cooler at injection energy and a Stochastic Cooling System from 1.5 GeV/c up to maximum momentum are available.

Vertically polarized proton beams with a polarization of more than 0.80 are delivered to external experiment areas at different momenta up to the maximum momentum of COSY. In the last year deuteron beams with different combinations of vector and tensor polarization were delivered to internal and external experiments.

In this report the status of the cooler synchrotron COSY is presented and future plans are discussed.
