Filed:

Nov 23, 2010

Appl. No.:

13/510362

Inventors:

Lloyd G. Clonts - Knoxville TN, US
Ronald G. Cooper - Oak Ridge TN, US

Assignee:

UT BATTELLE, LLC - Oak Ridge TN

International Classification:

G01T 3/06

US Classification:

250362, 250366

Abstract:

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.
