A neutron detection apparatus includes a neutron detector and an analyzer. The neutron detector includes a plurality of neutron detector assemblies, where each of the neutron detector assemblies includes a plurality of neutron detection devices. The neutron detector also includes a moderating volume. The plurality of neutron detector assemblies are disposed within the moderating volume so as to form a three-dimensional array of neutron detection devices within the moderating volume. The analyzer is communicatively coupled to each of the neutron detection devices of the plurality of neutron detector assemblies. The analyzer configured to receive one or more measured response signals from each of the neutron detection devices, and perform one or more analysis procedures to determine one or more characteristics associated with the one or more neutron sources based at least on the received one or more measured response signals.

Apparatus and method for the determination of one or more neutron source characteristics

A neutron detection system may include a neutron detector including a plurality of neutron detection devices, a plurality of discrete neutron moderating elements, wherein each of the neutron moderating elements is disposed between two or more neutron detection devices, the plurality of neutron detection devices and the plurality of discrete neutron moderating elements disposed along a common axis, a control system configured to generate a detector response library, wherein the detector response library includes one or more sets of data indicative of a response of the detector to a known neutron source, receive one or more measured neutron response signals from each of the neutron devices, the one or more measured response signals response to a detected neutron event, and determine one or more characteristics of neutrons emanating from a measured neutron source by comparing the one or more measured neutron response signals to the detector response library.

Apparatus and method for determination of one or more free neutron characteristics

A neutron detection system includes a plurality of neutron detector assemblies, the neutron detector assemblies including a plurality of neutron detection devices, wherein the neutron detection devices are configured to detect one or more characteristics of neutrons emanating from one or more neutron sources and impinging on one or more neutron detection devices; a plurality of discrete moderating elements, wherein each of the discrete moderating elements is disposed proximate to at least one neutron detector assembly, the plurality of neutron detector assemblies and the plurality of discrete moderating elements disposed along a common axis, wherein the discrete moderating elements are configured to moderate the energy of neutrons impinging on one or more of the neutron-photon detector assemblies; and a control system configured to: determine one or more characteristics associated with the one or more neutron sources based on the received one or more measured response signals.

Non-streaming high-efficiency perforated semiconductor neutron detectors, method of making same and measuring wands and detector modules utilizing same are disclosed. The detectors have improved mechanical structure, flattened angular detector responses, and reduced leakage current. A plurality of such detectors can be assembled into imaging arrays, and can be used for neutron radiography, remote neutron sensing, cold neutron imaging, SNM monitoring, and various other applications.
