安装了 NaI(Tl) 光谱仪系统，用于测量天体物理相关能量为 10 至 500keV 的原子核辐射中子俘获反应的横截面。该系统由两台大型反康普顿NaI(Tl)光谱仪和一个新的数据采集系统组成。光谱仪可以探测从中子俘获态到低位态迅速发射的离散γ射线，数据采集系统可以以更高的速率传输事件，与现有系统相比，大约高30倍。
An NaI(Tl) spectrometer system has been installed to measure the cross section of a radiative neutron-capture reaction of a nucleus at an astrophysically relevant energy of between 10 and 500keV. The system consists of two large anti-Compton NaI(Tl) spectrometers and a new data-taking system. The spectrometer can detect a discrete γ-ray emitted promptly from a neutron-capture state to its low-lying state, and the data-taking system can transfer events with much higher rates, about 30-times higher, compared to the existing system.
