Title: Breakup corrections to the He 3 beam polarization measurements at the future BNL Electron Ion Collider

Journal Article · · Physical Review C

Requirements for hadron polarimetry at the future Electron-Ion Collider (EIC) include measurements of absolute 3He (h) beam polarization with systematic uncertainties better than $$σ^{syst}_{P}$$/P ≲ 1%. Due to the successful use, since 2005, of the polarized hydrogen jet target polarimeter (HJET) to measure proton beam polarization at the Relativistic Heavy Ion Collider (RHIC), the HJET technique promises to be suitable for the 3He polarimetry at EIC. For that, however, one needs to know the ratio of the h↑p and p↑h analyzing powers. For elastic scattering, this ratio can be evaluated with sufficient accuracy if p↑p analyzing power is precisely known. In this paper, the deuteron beam data acquired at HJET in RHIC Run 16 was used to evaluate corrections to the measured helion beam polarization due to the 3He breakup. The breakup effect was found to be negligible if the ratio of the beam and target (jet) single spin asymmetries are concurrently measured to determine the 3He beam polarization.
