Single volume fission energy neutron detector
| DWPI Title: Single volume fission energy neutron detection system for detecting fission energy neutrons emitted from target, has kinematics of neutron indicative of location of target relative to scintillator block |
| Abstract: A single volume fission energy neutron detector is described herein. The detector includes a single volume of scintillator. A photodetector is positioned adjacent to a surface of the scintillator, wherein the photodetector has relatively small spatial resolution corresponding thereto and relatively small temporal resolution corresponding thereto. Based upon values read out from detection bins of the photodetector, kinematics of a neutron that interacted with scintillating material of the scintillator are reconstructed. Based upon the kinematics (of the neutron and other detected neutrons), a location of material from which the neutron was emitted is ascertained, and an image of the material is generated. |
| Use: Single volume fission energy neutron detection system of single volume of scintillator for detecting fission energy neutrons emitted from target. |
| Advantage: The sufficient amount of data is acquired to allow for reconstruction of neutron kinematics as the spatial resolution of the detection bins is relatively small, and as the temporal resolution for data readout by the readout circuit is relatively small. The detection system identifies fission energy neutrons with improved efficiency. |
| Novelty: The system (100) has a photodetector (112) with readout circuit that reads values from the position bins. A computing system (116) estimates kinematics of a neutron (118) interacted with scintillating material of scintillator block twice. The computing system estimates kinematics of neutron based upon values from detection bins read out by readout circuit. The kinematics of neutron indicative of a type of material of a target (104) from which the neutron is emitted and location of the target relative to the scintillator block. |
