论文摘要
在德国达姆施塔特（Darmstadt）的抗蛋白质和离子研究（FAIR）设施的相对论放射光束（R $^3 $ b）的反应，已构建了一种实验设置，以对核物质进行基本研究，使用作为相对能量的Exotic Nuclei的探针反应。 Among the various detection systems, one of the most recent upgrades consisted on the installation of a large area, around 2 m$^2$, multi-gap Resistive Plate Chamber (RPC), equipped with twelve 0.3 mm gaps and readout by 30 mm pitch strips, exhibiting a timing precision down to 50 ps and efficiencies above 98% for MIPs in a previous characterization of the detector. RPC是公平阶段0实验设置的一部分，该实验的重点是首次测量外来核（$^{16} $ c）内部的核子核子短距离相关（SRC），该核（$^{16} $ C）发生在2022年春季。该检测器的出色时光精确的准确性可以使该检测器的良好定时能力构成前元的分辨率，并在1％的脉冲量范围内进行了分辨率。在光束测量中，RPC效率超过95％，时间精度高于100 PS（包括参考闪烁体的贡献和颗粒的动量扩散），以便向前发射颗粒。
The Reactions with Relativistic Radioactive Beams (R$^3$B) collaboration of the Facility for Antiproton and Ion Research (FAIR) in Darmstadt, Germany, has constructed an experimental setup to perform fundamental studies of nuclear matter, using as a probe reactions with exotic nuclei at relativistic energies. Among the various detection systems, one of the most recent upgrades consisted on the installation of a large area, around 2 m$^2$, multi-gap Resistive Plate Chamber (RPC), equipped with twelve 0.3 mm gaps and readout by 30 mm pitch strips, exhibiting a timing precision down to 50 ps and efficiencies above 98% for MIPs in a previous characterization of the detector. The RPC was part of the setup of the FAIR Phase 0 experiment that focused on measuring, for the first time, nucleon-nucleon short-range correlations (SRC) inside an exotic nucleus ($^{16}$C) that occurred in Spring 2022. The excellent timing precision of this detector will allow the measurement of the forward emitted proton momentum with a resolution of around 1%. In beam measurements show an RPC efficiency above 95% and a time precision better than 100 ps (including the contribution of a reference scintillator and the momentum spread of the particles) for forward emitted particles.
