Phys. Rev. ST Accel. Beams 9, 050101 (2006) [13 pages]Determination of deuteron beam polarizations at COSYReceived 29 November 2005; published 16 May 2006 The vector (Pz) and tensor (Pzz) polarizations of a deuteron beam have been measured using elastic deuteron–carbon scattering at 75.6 MeV and deuteron-proton scattering at 270 MeV. After acceleration to 1170 MeV inside the COSY storage ring, the polarizations of the deuterons were remeasured by studying the analyzing powers of a variety of nuclear reactions. For this purpose a hydrogen cluster target was employed at the ANKE magnetic spectrometer, which is situated at an internal target position in the ring. The overall precisions obtained were about 4% for both Pz and Pzz. Though all the measurements were consistent with the absence of depolarization during acceleration, only an upper limit of about 6% could be placed on such an effect. ©2006 The American Physical Society
