Impact of three-dimensional polarization profiles on spin-dependent measurements in colliding beam experiments

“…The evaluations above assume that the beam polarization profiles (namely the profile parameters R x;y;s ) do not change from the polarimeter location in the ring to the experimental collision points, even if they are separated by ''Siberian snakes'' (magnets that flip the spin direction by 180 degrees), and by spin rotators (magnets that rotate the spin from vertical to longitudinal or horizontal, and back) [1]. This is a separate topic for careful investigation and confirmation.…”

“…The Relativistic Heavy Ion Collider (RHIC) is the only collider of spin polarized protons [1]. During beam acceleration and storage the polarization P evolves.…”

Operations and Performance of RHIC as a Cu-Cu Collider

“…Luminosity for the Cu-Cu run at 100GeVIc Figure 1 summarizes RHIC performance in the Cu-Cu high energy run. Measured integrated luminosity at the 4 experiments (beams collided at Star and Phenix with p*=0.90, at Brahms with pY=2.6 m and at Phobos with p*=3m) is compared to the minimum and maximum luminosity projections [3] used for run planning. Minimum projections were based on RHIC performance in Run-4 with Au and assuming the same charge per bunch with Cu ions.…”

Effect of 3D Polarization profiles on polarization measurements and colliding beam experiments

“…The Relativistic Heavy Ion Collider (RHIC) is the only collider of spin polarized protons [2]. During beam acceleration and storage profiles of the polarization P develop, which affect the polarization measured in a polarimeter, and the polarization and figure of merit (F OM ) in colliding beam experiments.…”
