PANDORA（Particle Analyzer Neutron Detector Of Real-time Acquisition）系统是一种基于塑料闪烁体和数字读出器的中子探测器，它是为不稳定同位素束的逆运动学实验而研制的。PANDORA可用于任何涉及低能中子（100 keV-10 MeV）发射的反应研究，其中背景抑制和提高信噪比至关重要。数字读出系统提供了一个机会，脉冲形状歧视（PSD）的检测粒子以及智能触发的基础上。将PANDORA的优值结果与文献中的数据进行了比较。使用PANDORA，可以分离91±1%的所有探测到的中子，同时可以排除91±1%的探测到的伽马射线，将伽马射线背景降低一个数量级。
Abstract The PANDORA (Particle Analyzer Neutron Detector Of Real-time Acquisition) system, which was developed for use in inverse kinematics experiments with unstable isotope beams, is a neutron detector based on a plastic scintillator coupled to a digital readout. PANDORA can be used for any reaction study involving the emission of low energy neutrons (100 keV–10 MeV) where background suppression and an increased signal-to-noise ratio are crucial. The digital readout system provides an opportunity for pulse shape discrimination (PSD) of the detected particles as well as intelligent triggering based on PSD. The figure of merit results of PANDORA are compared to the data in literature. Using PANDORA, 91±1% of all detected neutrons can be separated, while 91±1% of the detected gamma rays can be excluded, reducing the gamma ray background by one order of magnitude.
