Determination of Deuteron Beam Polarizations at COSY — •David Chiladze — IKP, Forschungszentrum Jülich

The vector and tensor polarizations of a deuteron beam have been measured using elastic deuteron-carbon scattering at 76 MeV and deuteron-proton scattering at 270 MeV. After acceleration to 1170 MeV inside the COSY ring, the polarization of the deuteron beam was checked by studying a variety of nuclear reactions with the ANKE magnetic spectrometer placed at an internal target position of the storage ring. All these measurements were consistent with the absence of depolarization during acceleration and provide us with a series of secondary standards that can be used in subsequent experiments at the COSY-ANKE facility. Final results obtained in these measurement will be presented and discussed.
