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.

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.

International Classification:

G01T 1/20

US Classification:

250362, 25030133, 25030136, 2503014 R

Abstract:

New metal-organic materials are useful as scintillators and have the chemical formula LX(CHOH)where L is Y, Sc, or a lanthanide element, and X is a halogen element. An example of the scintillator materials is CeCl(CHOH).

G01T 3/06

US Classification:

25230117, 252646, 25039011

Abstract:

The invention is directed to a liquid scintillating composition containing (i) one or more non-polar organic solvents; (ii) (lithium-6)-containing nanoparticles having a size of up to 10 nm and surface-capped by hydrophobic molecules; and (iii) one or more fluorophores. The invention is also directed to a liquid scintillator containing the above composition.
