【 摘 要 】

During the RHIC run-4 polarized proton operation, the intensity and polarization profiles were measured by scanning the Coulomb-nuclear interference (CNI) polarimeter targets across the beam. The scans reported here were all performed on flattop at beam momenta {approx}100 GeV/c, and all but one was a vertical scan, since several of the vertical polarimeter targets had broken by the time of the measurements. This note summarizes some analyses of these profiles. Wall current monitor data are compared to these results for one beam and fill.
