Determination of the Analyzing Power Ay in quasi-free pp and np scattering with a Silicon Tracking Telescope at ANKE — •Andreas Mussgiller — Institut für Kernphysik, Forschungszentrum Jülich — now at Physikalisches Institut II, Universität Erlangen-Nürnberg
A beam-time in November of 2003 has been exploited to take data with a Silicon Tracking Telescope that has been developed for the ANKE spectrometer. In the experiment a deuteron beam of 2.4 GeV/c with eight different combinations of vector and tensor polarizations impinged on an unpolarized hydrogen cluster jet target.
From the obtained data it was possible to determine the analyzing powers Ay and Ayy for dp-elastic, and Ay for pp- and np-quasi elastic scattering. The performance of the Silicon Tracking Telescope and the analysis will be outlined, and first results will be presented.
