A ceramic lithium indium diselenide or like radiation detector device formed as a pressed material that exhibits scintillation properties substantially identical to a corresponding single crystal growth radiation detector device, exhibiting the intrinsic property of the chemical compound, with an acceptable decrease in light output, but at a markedly lower cost due to the time savings associated with pressing versus single crystal growth.

Ceramic radiation detector device and method

A wide band gap semiconductor NAND based neutron detection system includes a semiconductor layer comprising a wide band gap material with a neutron absorber material in the wide band gap material, and the semiconductor layer is the only layer of the wide band gap semiconductor NAND based neutron detection system fabricated with the neutron absorber material.

Wide band gap semiconductor NAND based neutron detection systems and methods

Techniques are disclosed for systems and methods to provide a radiation detector module for a radiation detector. A radiation detector module includes a metallic and/or metalized enclosure, a radiation sensor disposed within the enclosure, readout electronics configured to provide radiation detection event signals corresponding to incident ionizing radiation in the radiation sensor, and a cap including an internal interface configured to couple to the readout electronics and an external interface configured to couple to a radiation detector, where the cap is configured to hermetically seal the radiation sensor within the enclosure. The cap may be implemented as an edge plated printed circuit board (PCB) including a slot configured to mate with a planar edge of an open surface of the enclosure, where the slot is soldered to the planar edge of the enclosure to hermetically seal the radiation sensor within the enclosure.

Sealed radiation detector module systems and methods

Techniques are disclosed for systems and methods to detect radiation accurately, and particularly in a highly radioactive environment. A system includes a detector module for a radiation detector and a parallel signal analyzer configured to receive radiation detection event signals from the detector module and provide a spectroscopy output and a dose rate output. The parallel signal analyzer may be configured to analyze the radiation detection event signals in parallel in first and second analysis channels according to respective first and second measurement times and determine the spectroscopy output and the dose rate output based on radiation detection event energies determined according to the respective first and second measurement times.

Dose rate measurement systems and methods

Techniques are disclosed for systems and methods to provide a radiation detector module for a radiation detector. A radiation detector module an enclosure, a radiation sensor separated from the enclosure by one or more damping inserts, readout electronics configured to provide radiation detection event signals corresponding to incident ionizing radiation in the radiation sensor, and a cap comprising an internal interface configured to couple to the readout electronics and an external interface configured to couple to a radiation detector, wherein the cap is configured to hermetically seal the radiation sensor within the enclosure. Plated edges of the cap can be soldered to the enclosure to hermetically seal the radiation sensor within the enclosure.

Radiation detector module systems and methods

A chalcopyrite, colquiriite, neutron absorber loaded glass, or plastic scintillator based fiber optic plate for use in a neutron imaging system, including: a plurality of optical fiber segments disposed side-by-side adjacent to one another in a parallel array; and a binder material disposed between and coupling the plurality of optical fiber segments together. A diffuse reflective material is optically coupled to the plurality of first ends of the plurality of optical fiber segments. An optical detector device is optically coupled to the plurality of second ends of the plurality of optical fiber segments opposite the diffuse reflective material. Optionally, the fiber optic plate further includes a diffuse reflective material disposed one or more of on an exterior surface of each of the plurality of optical fiber segments and between the plurality of optical fiber segments.

Scintillator based fiber optic plate for neutron imaging applications and the like

Techniques are disclosed for systems and methods using silicon photomultiplier (SiPM) based radiation detectors to detect radiation in an environment. An SiPM-based radiation detection system may include a number of detector assemblies, each including at least one scintillator providing light to a corresponding SiPM in response to ionizing radiation entering the scintillator. The radiation detection system may include a logic device and a number of other electronic modules to facilitate reporting, calibration, and other processes. The logic device may be adapted to process detection signals from the SiPMs to implement different types of radiation detection procedures. The logic device may also be adapted to use a communication module to report detected radiation to an indicator, a display, and/or a user interface.

SiPM-based radiation detection systems and methods

A highly scalable platform for radiation measurement data collection with high precision time stamping and time measurements between the elements in the detection array uses IEEE 1588 with or without Synchronous Ethernet (timing over Ethernet) to synchronize the measurements. At a minimum, the system includes at least two radiation detector units, an IEEE 1588 and SyncE enabled Ethernet switch, and a computer for processing. The addition of timing over Ethernet and power over Ethernet (PoE) allows a radiation measurement system to operate with a single Ethernet cable, simplifying deployment of detectors using standardized technology with a multitude of configuration possibilities. This eliminates the need for an additional hardware for the timing measurements which simplifies the detection system, reduces the cost of the deployment, reduces the power consumption of the detection system and reduces the overall size of the system.
