Dual Neutron Flux/Temperature Measurement Sensor

View page
US Patent:
6471888, Oct 29, 2002
Filed:
Dec 12, 1995
Appl. No.:
08/571307
Inventors:
John T. Mihalczo - Oak Ridge TN
Marc L. Simpson - Knoxville TN
Stephanie A. McElhaney - Oak Ridge TN
Assignee:
UT-Battelle, LLC - Oak Ridge TN
International Classification:
G01T 1164
US Classification:
25230117, 25230118, 25230134, 25230135, 25230136, 2504721, 2504831, 2504842, 2504843, 25039011
Abstract:
Simultaneous measurement of neutron flux and temperature is provided by a single sensor which includes a phosphor mixture having two principal constituents. The first constituent is a neutron sensitive Li F and the second is a rare-earth activated Y O thermophosphor. The mixture is coated on the end of a fiber optic, while the opposite end of the fiber optic is coupled to a light detector. The detected light scintillations are quantified for neutron flux determination, and the decay is measured for temperature determination.

Fiber Optic Thermal/Fast Neutron And Gamma Ray Scintillation Detector

View page
US Patent:
7141799, Nov 28, 2006
Filed:
Mar 30, 2005
Appl. No.:
11/094679
Inventors:
John S. Neal - Knoxville TN, US
John T. Mihalczo - Oak Ridge TN, US
Assignee:
UT-Battelle, LLC - Oak Ridge TN
International Classification:
G01T 3/06
US Classification:
25039011
Abstract:
A detector system that combines a Li loaded glass fiber scintillation thermal neutron detector with a fast scintillation detector in a single layered structure. Detection of thermal and fast neutrons and ionizing electromagnetic radiation is achieved in the unified detector structure. The fast scintillator replaces the polyethelene moderator layer adjacent the Li loaded glass fiber panel of the neutron detector and acts as the moderator for the glass fibers. Fast neutrons, x-rays and gamma rays are detected in the fast scintillator. Thermal neutrons, x-rays and gamma rays are detected in the glass fiber scintillator.

Fiber Optic Thermal/Fast Neutron And Gamma Ray Scintillation Detector

US Patent:
7288771, Oct 30, 2007
Filed:
Oct 13, 2006
Appl. No.:
11/549269
Inventors:
John S. Neal - Knoxville TN, US
John T Mihalczo - Oak Ridge TN, US
Assignee:
UT-Battelle LLC - Oak Ridge TN
International Classification:
G01T 3/06
US Classification:
25039011
Abstract:
A system for detecting fissile and fissionable material originating external to the system includes: a Li loaded glass fiber scintillator for detecting thermal neutrons, x-rays and gamma rays; a fast scintillator for detecting fast neutrons, x-rays and gamma rays, the fast scintillator conjoined with the glass fiber scintillator such that the fast scintillator moderates fast neutrons prior to their detection as thermal neutrons by the glass fiber scintillator; and a coincidence detection system for processing the time distributions of arriving signals from the scintillators.

Interrogating Hidden Contents Of A Container

US Patent:
7970103, Jun 28, 2011
Filed:
Jun 5, 2009
Appl. No.:
12/455694
Inventors:
Michael V. Hynes - Cambridge MA, US
Bernard Harris - Waltham MA, US
Brandon Blackburn - Idaho Falls ID, US
John E. McElroy - North Andover MA, US
Richard C. Lanza - Brookline MA, US
Timothy A. Antaya - Hampton Falls NH, US

John T. Mihalczo - Oak Ridge TN, US
Paul A. Hausladen - Oak Ridge TN, US
Alan W. Hunt - Pocatello ID, US
Hugh R. Andrews - Pembroke CA, US
James Johnson - Rigby ID, US
Assignee:
Raytheon Company - Waltham MA
International Classification:
G01N 23/04
H05G 1/52
H01J 35/30
US Classification:
378 57, 378113, 378137
Abstract:
According to one embodiment, a system for interrogating hidden contents of a container comprises a controller, a detector system, and a data system. The controller receives a selection of a source mode of source radiation to generate to interrogate contents of a container. The source mode selection comprises a neutron mode, a gamma ray mode, or a combined neutron-gamma ray mode. The controller instructs a cyclotron to generate the source radiation according to the source mode selection. The detector system detects radiation emitted from the contents in response to the source radiation. The data system analyzes the emitted radiation and describes the contents according to the analysis.

High Spatial Resolution Particle Detectors

US Patent:
8258483, Sep 4, 2012
Filed:
May 5, 2011
Appl. No.:
13/101741
Inventors:
Lynn A. Boatner - Oak Ridge TN, US
John T. Mihalczo - Oak Ridge TN, US
Assignee:
UT-Battelle, LLC - Oak Ridge TN
International Classification:
G01T 3/06
G01T 1/20
G01N 23/09
US Classification:
25039011, 250367
Abstract:
Disclosed below are representative embodiments of methods, apparatus, and systems for detecting particles, such as radiation or charged particles. One exemplary embodiment disclosed herein is particle detector comprising an optical fiber with a first end and second end opposite the first end. The optical fiber of this embodiment further comprises a doped region at the first end and a non-doped region adjacent to the doped region. The doped region of the optical fiber is configured to scintillate upon interaction with a target particle, thereby generating one or more photons that propagate through the optical fiber and to the second end. Embodiments of the disclosed technology can be used in a variety of applications, including associated particle imaging and cold neutron scattering.

International Classification:
G01T 3/00
US Classification:
25039002
Abstract:
Disclosed herein are representative embodiments of methods, apparatus, and systems for performing neutron radiography. For example, in one exemplary method, an object is interrogated with a plurality of neutrons. The plurality of neutrons includes a first portion of neutrons generated from a first neutron source and a second portion of neutrons generated from a second neutron source. Further, at least some of the first portion and the second portion are generated during a same time period. In the exemplary method, one or more neutrons from the first portion and one or more neutrons from the second portion are detected, and an image of the object is generated based at least in part on the detected neutrons from the first portion and the detected neutrons from the second portion.
