Precision small scattering angle measurements of proton-proton and proton-nucleus analyzing powers at the RHIC hydrogen jet polarimeter

A. A. Poblaguev, A. Zelenski, E. Aschenauer +7

At RHIC, the hydrogen jet target polarimeter (HJET) is used to measure proton beam polarization with accuracy ${\sigma }_P^{\text{syst}}/P\lesssim 0.5\%$ by counting low energy (1--10 MeV) re…
