RHIC PERFORMANCE AS POLARIZED PROTONS COLLIDER IN RUN-6*

The Relativistic Heavy Ion Collider in Run-6 was operating in polarized proton mode. Polarization was maintained with two Siberian Snakes per ring. Beams were colliding with 100 GeV and 31.2 GeV energies. The control of polarization orientation at STAR and PHENIX experiments was done using helical spin rotators. Physics data were taken with longitudinal, vertical and horizontal beam polarization at the collision points. This paper presents the performance of RHIC as a polarized proton collider in the Run-6 with emphasis on beam polarization and luminosity issues.
