Patent number: 9366769Abstract: For each photomultiplier tube in an Anger camera, an R×S array of preamplifiers is provided to detect electrons generated within the photomultiplier tube. The outputs of the preamplifiers are digitized to measure the magnitude of the signals from each preamplifier. For each photomultiplier tube, a corresponding summation circuitry including R row summation circuits and S column summation circuits numerically add the magnitudes of the signals from preamplifiers for each row and for each column to generate histograms. For a P×Q array of photomultiplier tubes, P×Q summation circuitries generate P×Q row histograms including R entries and P×Q column histograms including S entries. The total set of histograms include P×Q×(R+S) entries, which can be analyzed by a position calculation circuit to determine the locations of events (detection of a neutron).Type: GrantFiled: January 15, 2013Date of Patent: June 14, 2016Assignee: UT-BATTELLE, LLCInventors: Lloyd G. Clonts, Yacouba Diawara, Cornelius Donahue, Jr., Christopher A. Montcalm, Richard A. Riedel, Theodore Visscher

Patent number: 8664608Abstract: Provided are sensors and methods for detecting thermal neutrons. Provided is an apparatus having a scintillator for absorbing a neutron, the scintillator having a back side for discharging a scintillation light of a first wavelength in response to the absorbed neutron, an array of wavelength-shifting fibers proximate to the back side of the scintillator for shifting the scintillation light of the first wavelength to light of a second wavelength, the wavelength-shifting fibers being disposed in a two-dimensional pattern and defining a plurality of scattering plane pixels where the wavelength-shifting fibers overlap, a plurality of photomultiplier tubes, in coded optical communication with the wavelength-shifting fibers, for converting the light of the second wavelength to an electronic signal, and a processor for processing the electronic signal to identify one of the plurality of scattering plane pixels as indicative of a position within the scintillator where the neutron was absorbed.Type: GrantFiled: November 23, 2010Date of Patent: March 4, 2014Assignee: UT-Battelle, LLCInventors: Lloyd G.

Patent number: 8115179Abstract: 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.Type: GrantFiled: September 15, 2010Date of Patent: February 14, 2012Assignee: UT-BattelleInventors: Richard A.

Patent number: 7142167Abstract: A proximity detection system for determining when a single channel receiver becomes proximate to any point on a wireless closed boundary continuously generated by a transmitter. The transmitter includes a magnetic field generator broadcasting a composite, modulated, time-varying magnetic field signal of a particular carrier frequency. The receiver forms a measure of the broadcast magnetic field intensity incident to the location of the receiver or a measure of the power or energy of incident field.Type: GrantFiled: November 4, 2004Date of Patent: November 28, 2006Assignee: CMS Partners, Inc.Inventors: James M. Rochelle, David M. Binkley, Lloyd G. Clonts, Brian K. Swann, Rungwit Sangsingkeow
