The RHIC Spin Group of the BNL Physics Department supported through DOE Medium Energy

The purpose of the RHIC Spin Group is to provide leadership and support for the RHIC spin program at BNL, and to provide for the common requirements of the spin program, particularly for polarimetry. STAR and PHENIX spin, and polarimetry are combined within one group.

The goal of the RHIC spin program is to understand the spin structure of the proton, using the strongly interacting probes, quarks and gluons.

CNI Polarimetry at RHIC

The CNI polarimetery group develops, maintains and operates polarimeters in the Relativistic Heavy Ion Collider (RHIC) complex. These include the CNI polarimeter in AGS and the p-Carbon and polarized H-jet polarimeters in RHIC. The group provides the final polarization values essential for the analysis of the polarized RHIC data.

Spin Physics at STAR and PHENIX

The group is involved in a number of analyses dedicated to spin studies with the STAR and PHENIX detectors at RHIC Important recent documents the group has contributed to summarize and plan the future of the RHIC Cold QCD program at RHIC

EIC/eRHIC Project

Members of the RHIC Spin group collaborate with physicists around the world to realize a powerful new facility in the United States with the aim of studying gluons. This new facility, known as the Electron-Ion Collider (EIC), would collide intense beams of spin-polarized electrons with intense beams of both polarized nucleons and unpolarized nuclei from deuterium to uranium. Large, new detectors are being designed to detect the high-energy scattered particles as well as the low-energy debris as a means to definitively understand how the matter we are all made of is bound together.
