Abstract
The Spin Physics Detector is an experiment at NICA designed to study the spin structure of the proton and deuteron and the other spin-related phenomena using polarized beams. Two endcap detector wheels of scintillator-based Beam-Beam Counters (BBCs) will be installed symmetrically aside from the interaction point and will serve as a tool for beam diagnostics including local polarimetry. The selection of material combinations for BBC is presented using scintillation tiles with different material combinations of the BBC prototype. The influence of the light collection was studied using matted and covered with Tyvek tiles. Different fibers (Saint-Gobain Crystals BCF91AS, BCF92S, and Kuraray Y-11), as well as different optical cements (CKTN type E, OK-72) were used. The prototypes were tested with cosmic rays and radioactive source using SensL SiPM readout.
摘要 "自旋物理探测器 "是美国国家核物理研究所的一项实验，旨在利用偏振光束研究质子和氘核的自旋结构以及其他与自旋有关的现象。两个基于闪烁体的光束-光束计数器（BBC）端盖探测器轮将对称地安装在相互作用点的一侧，并将作为光束诊断工具，包括局部偏振测量。利用闪烁瓦和 BBC 原型的不同材料组合，介绍了 BBC 材料组合的选择。使用无光泽和覆盖特卫强（Tyvek）瓷砖研究了光收集的影响。使用了不同的纤维（圣戈班水晶 BCF91AS、BCF92S 和可乐丽 Y-11）以及不同的光学胶结剂（CKTN E 型、OK-72）。使用 SensL SiPM 读出器对原型进行了宇宙射线和放射源测试。
期刊介绍：
The journal Fizika Elementarnykh Chastits i Atomnogo Yadr of the Joint Institute for Nuclear Research (JINR, Dubna) was founded by Academician N.N. Bogolyubov in August 1969. The Editors-in-chief of the journal were Academician N.N. Bogolyubov (1970–1992) and Academician A.M. Baldin (1992–2001). Its English translation, Physics of Particles and Nuclei, appears simultaneously with the original Russian-language edition. Published by leading physicists from the JINR member states, as well as by scientists from other countries, review articles in this journal examine problems of elementary particle physics, nuclear physics, condensed matter physics, experimental data processing, accelerators and related instrumentation ecology and radiology.
