The cooler synchrotron COSY delivers unpolarized and polarized protons
and deuterons in the momentum range 300 MeV/c up to 3.65 GeV/c. Electron
cooling at injection level and stochastic cooling covering the range from
1.5 GeV/c up to maximum momentum are available to prepare high precision
beams for internal as well as for external experiments in hadron physics.
In case of electron cooled beam the intensity is limited by transverse
instabilities. The major losses are due to the vertical coherent beam
oscillations. To damp these instabilities a transverse feedback system is
under construction. First results with a simple feedback system are
presented. Due to the feedback system operation the intensity and
lifetime of the electron cooled proton beam at injection energy could be
significantly increased. Measurements in frequency and time domain
illustrate the performance of the system.
