摘要

讨论了在U-70加速器设施（俄罗斯国家研究中心库尔恰托夫研究所高能物理研究所）的SPASCHARM实验中弹性质子-质子和反质子-质子散射的自旋效应。实验将使用偏振光束或偏振靶来测量质子和反质子弹性散射的分析能力$A_{N}$。分析了用两种不同类型的探测器记录质子弹性散射反冲粒子的可能性。在第一种情况下，建议使用闪烁计数器，第二种选择是基于比例室的检测器。比较了弹性$pp$散射在两种实验装置配置下的配准效率，确定了所需的测量时间。

Measurement of the Analyzing Power of ${pp}$ and $\bar{{p}}{{p}}$ Elastic Scattering at the SPASCHARM Facility at U-70

The study of spin effects in elastic proton–proton and antiproton–proton scattering in the SPASCHARM experiment at U-70 accelerator facility (Institute for High Energy Physics, National Research Centre Kurchatov Institute, Protvino, Moscow oblast) is discussed. Polarized beams or a polarized target of the experiment will be used to measure the analyzing power $A_{N}$ of elastic scattering of protons and antiprotons. The possibility of using two different types of the detectors to register recoil particles of elastic scattering of protons is analyzed. In the first case, it is proposed to use scintillation counters, the second option is a detector based on proportional chambers. A comparison of the registration efficiency of elastic $pp$ scattering for two configurations of the experimental setup is carried out, and the required measurement time is determined.
