Tagged neutron-based experimental system has been developed with a laboratory D-T neutron generator at BARC. The system can identify the C, N, O elemental signatures from an interrogated object (explosive or benign) using the Associated Particle Technique (also known as tagged neutron method) employing alpha–gamma coincidence and time-of-flight methodology. The system consists of a matrix of 64-pixel YAP:Ce α-particle detectors incorporated in the neutron generator and a BGO (3″ × 3″) gamma detector. Main parameters of the system were investigated, and its performance was evaluated through various experiments performed at laboratory environment. The experimental results of pure element spectra (graphite for Carbon, water for Oxygen), complex sample (melamine) spectrum and study of explosive simulant (RDX) spectrum have demonstrated the successful implementation of the tagged neutron method.

基于标记中子的实验系统已经在BARC上使用实验室DT中子发生器进行了开发。该系统可以使用α-γ重合和飞行时间方法，使用关联粒子技术（也称为标记中子方法）从被询问物体（爆炸或良性）中识别C，N，O元素特征。该系统由一个结合在中子发生器中的64像素YAP：Ceα粒子探测器和一个BGO（3“×3”）伽马探测器组成的矩阵。研究了系统的主要参数，并通过在实验室环境下进行的各种实验来评估其性能。纯元素光谱（石墨表示碳，水表示氧气）的实验结果，
