摘要：
重离子实验紧凑型谱仪（Compact Spectrometer for Heavy Ion Experiment，CSHINE）正在建造中，旨在通过 Hanbury Brown–Twiss（HBT）粒子关联函数研究同位旋年代学，以及非对称核物质的核状态方程。CSHINE 由硅条探测器（silicon strip detector，SSD）望远镜和大面积平行板雪崩计数器组成，分别用于测量轻带电粒子和裂变碎片。在第一阶段，两台 SSD 望远镜被用于观测 30 MeV/u 的 ⁴⁰Ar + ¹⁹⁷Au 反应。本文给出的结果表明，氢和氦以很高的同位素分辨率被观测到，并且可以由所获得的数据构建轻带电粒子的 HBT 关联函数。
英文摘要：
The Compact Spectrometer for Heavy Ion Experiment (CSHINE) is under construction for the study of isospin chronology via the Hanbury Brown$-$Twiss (HBT) particle correlation function and the nuclear equation of state of asymmetrical nuclear matter. The CSHINE consists of silicon strip detector (SSD) telescopes and large-area parallel plate avalanche counters, which measure the light charged particles and fission fragments, respectively. In phase I, two SSD telescopes were used to observe 30 MeV/u $^{40}$Ar +$^{197}$Au reactions. The results presented here demonstrate that hydrogen and helium were observed with high isotopic resolution, and the HBT correlation functions of light charged particles could be constructed from the obtained data.
