摘要

The Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory has been operating since 2000. Over the past decade, thanks to the continuously increased bunch intensity and reduced ${ensuremath{eta}}^{*}mathrm{s}$ at the interaction points, the peak luminosity in the polarized proton operation has been increased by more than two orders of magnitude. In this article, we will present the operational observations at the routine proton physics stores. The mechanisms for the beam loss, transverse emittance growth, and bunch lengthening are analyzed. Numerical calculations and multiparticle tracking are used to model these observations.
