| 20080272308 | HEMISPHERICAL RADIATION DETECTOR - A detector is provided that includes a plurality of layered hemispherically shaped elements. Each element is configured to sense the detection of an event. The detector further includes a lead for each element. Each lead is configured to pass a detection signal when its associate element detects an event. | 11-06-2008 |
| 20090166550 | ARRAYED NEUTRON DETECTOR WITH MULTI SHIELDING ALLOWING FOR DISCRIMINATION BETWEEN RADIATION TYPES - Neutron detectors including one or more gamma shields over memory dies and methods of making the neutron detectors are provided. The neutron detectors can contain two or more memory dies, neutron-reactant layers over the two or more memory dies, and one or more gamma shields over at least a portion of or an entire of the two or more memory dies. By containing the gamma shield over the at least a portion of or an entire of the two or more memory dies, the neutron detector can detect and discriminate neutrons in the presence of gamma rays. | 07-02-2009 |
| 20110001055 | RADIATION DETECTION SYSTEM - A preamplifier circuit for processing a signal provided by a radiation detector includes a transimpedance amplifier coupled to receive a current signal from a detector and generate a voltage signal at its output. A second amplification stage has an input coupled to an output of the transimpedance amplifier for providing an amplified voltage signal. Detector electronics include a preamplifier circuit having a first and second transimpedance amplifier coupled to receive a current signal from a first and second location on a detector, respectively, and generate a first and second voltage signal at respective outputs. A second amplification stage has an input coupled to an output of the transimpedance amplifiers for amplifying the first and said second voltage signals to provide first and second amplified voltage signals. A differential output stage is coupled to the second amplification stage for receiving the first and second amplified voltage signals and providing a pair of outputs from each of the first and second amplified voltage signals. Read out circuitry has an input coupled to receive both of the pair of outputs, the read out circuitry having structure for processing each of the pair of outputs, and providing a single digital output having a time-stamp therefrom. | 01-06-2011 |
| 20110042577 | FAST NEUTRON DETECTOR HAVING AN OPEN-STRUCTURED HYDROGENOUS RADIATOR - A detector for fast neutrons has been developed which includes 1) selected open structure of solid hydrogen-containing material which converts impinging neutrons into recoil protons; 2) a surrounding gas which interacts with the protons to release electrons; 3) an electric field able to drift the electrons through and away from the open-structure material; and 4) an electron detector which monitors the drifted electrons thereby sensing the original impinging neutrons. This type of detector is advantageous for many applications, including efficient fast neutron detection; large area imaging of fast neutrons for fast neutron radiography; or fast neutron beam profiling. | 02-24-2011 |
| 20130062531 | BORON CONTAINING COATING FOR NEUTRON DETECTION - A neutron detector includes an exterior shell bounding an interior volume. The neutron detector includes at least a wall portion serving as a cathode. In one example the wall portion has microfeatures. The neutron detector includes a central structure located within the interior volume and serving as an anode. The neutron detector includes a boron coating on the wall portion. In on example, the boron coating is applied by an electrostatic spray process. In one example, the boron coating conforms to the microfeatures on the wall portion. In one example, the wall portion has a thickness of between 2 to 5 microns. The neutron detector includes an electrical connector operatively connected to the central structure for transmission of a signal collected by the central structure. An associated method provides for depositing the boron coating. | 03-14-2013 |
