本文设计并表征了一种便携式中子散射相机，通过硬件与逻辑触发组合实现各向同性响应，并利用360°全景相机精确定位中子源，以支持散裂设施中中子场测量及本底抑制。
AI 中文摘要
我们描述了一种中子散射相机的设计和性能表征，该相机专门用于研究散裂设施实验区域中的中子场（通量、能量、方向），在这些区域中多个中子源可能同时贡献。硬件和逻辑触发器的组合提供了该应用所需的各向同性响应。中子源位置通过内置360°全景相机在图像上被精确重建。该设备提供的中子场的完整理解可用于场地选择和减少中子本底，这些本底会影响灵敏仪器，例如即将在欧洲散裂源安装的相干弹性中微子-核散射（CEνNS）探测器。
英文摘要
We describe the design and characterization of a neutron scatter camera specifically developed for the study of neutron fields (flux, energy, direction) in experimental areas of spallation facilities, where multiple neutron sources can simultaneously contribute. A combination of hardware and logic triggers provides the isotropic response required for this application. Neutron source locations are accurately reconstructed on images from a built-in 360$^\circ$ panoramic camera. The full understanding of neutron fields that the device provides can be used for site selection and abatement of neutron backgrounds affecting sensitive instruments such as coherent elastic neutrino-nucleus scattering (CE$ν$NS) detectors to be located at the upcoming European Spallation Source.
