Detector array for a radiation system, and related system
A detector array for a radiation system includes a radiation detection sub-assembly, a routing sub-assembly, and an electronics sub-assembly. The routing sub-assembly is disposed between the radiation detection sub-assembly and the electronics sub-assembly and includes one or more layers of shielding material. For example, the routing sub-assembly may include a printed circuit board having embedded therein a shielding material configured to shield the electronics sub-assembly from at least some radiation. In some embodiments, the shielding material defines at least one opening through which a conductive element(s) passes to deliver signals between the radiation detection sub-assembly and the electronics sub-assembly.
Radiation Detector with Two-Dimensional Directionality
Disclosed is a directional gamma ray or neutron detector that locates a source both horizontally and vertically. In some embodiments, the detector comprises four rod scintillators around a shield, and an orthogonal panel scintillator mounted frontward of the rod scintillators. The azimuthal angle of the source may be calculated according to the detection rates of the rod scintillators, while the polar angle of the source may be calculated from the panel scintillator rate using a predetermined angular correlation function. Thus, the exact location of the source can be found from a single data set without iterative rotations. Embodiments of the detector enable rapid detection and precise localization of clandestine nuclear and radiological weapons in applications ranging from hand-held survey meters and walk-through portals, to vehicle cargo inspection stations and mobile area scanners. Such detectors are needed to detect clandestine nuclear weapons worldwide.
Structured detectors and detector systems for radiation imaging
