中子探测器阵列(NEDA)项目旨在建造一种新的高效紧凑型中子探测器阵列，以便与AGATA等大型射线阵列相耦合。NEDA的应用范围从用于聚变-蒸发反应的选择性中子多重数过滤器到大立体角中子标记装置。在本工作中，我们用蒙特卡罗技术模拟了NEDA与中子壁耦合的早期实现的可能构型，以评估它们的性能指标。与以前的仪器相比，这一早期NEDA实施的目标是提高效率和为发射1、2或3个中子的聚变-蒸发反应通道选择多重性的能力。每个NEDA探测器单元具有约3.23L的正六角棱镜形状，并填充了EJ301液体闪烁体，具有良好的中子识别性能。用聚变-蒸发事件发生器进行了模拟，并用中子壁探测器阵列测量的58Ni+56Fe反应的一组实验数据进行了验证。
The NEutron Detector Array (NEDA) project aims at the construction of a new high-efficiency compact neutron detector array to be coupled with large-ray arrays such as AGATA. The application of NEDA ranges from its use as selective neutron multiplicity filter for fusion-evaporation reaction to a large solid angle neutron tagging device. In the present work, possible configurations for the NEDA coupled with the Neutron Wall for the early implementation with AGATA has been simulated, using Monte Carlo techniques, in order to evaluate their performance figures. The goal of this early NEDA implementation is to improve, with respect to previous instruments, efficiency and capability to select multiplicity for fusion-evaporation reaction channels in which 1, 2 or 3 neutrons are emitted. Each NEDA detector unit has the shape of a regular hexagonal prism with a volume of about 3.23l and it is filled with the EJ301 liquid scintillator, that presents good neutron-discrimination properties. The simulations have been performed using a fusion-evaporation event generator that has been validated with a set of experimental data obtained in the58Ni +56Fe reaction measured with the Neutron Wall detector array.
