摘要：
At RHIC, the hydrogen jet target polarimeter (HJET) is used to measure proton beam polarization with the accuracy of sigma(syst)(P)/P less than or similar to 0.5% by counting low-energy (1-10 MeV) recoil protons in left-right symmetric detectors. The HJET performance also allowed us to precisely measure pp and pA (where A is any ion stored at RHIC) analyzing powers in the CNI region. The results of the measurements are discussed.
