论文摘要
在RHIC，氢气目标极化计（HJET）用于用精度$σ_p^\ text {syst}/p \ lessssim0.5 \％$来测量质子束极化，通过计数左右右手对称探测器中的低能（1--10 MEV）后退质子。 HJET的性能还使我们能够精确地测量$ PP $和$ p $ a（在RHIC中存储的任何离子）分析CNI地区的权力。讨论了测量结果。
At RHIC, the hydrogen jet target polarimeter (HJET) is used to measure proton beam polarization with accuracy $σ_P^\text{syst}/P\lesssim0.5\%$ 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 $p$A (where A is any ion stored at RHIC) analyzing powers in the CNI region. The results of the measurements are discussed.
