Lithiated Glass Scintillating-Particle Neutron Detector
11-G00209_ID1215.pdf (452 KB)
The configured detecting material is placed near at least one detector element sensitive to light, which produces an electrical signal when a neutron is absorbed. Multiple detector elements can rapidly accumulate data from a chamber. At least one detector element can also feature first and second arrays of optical fibers, spaced apart so that the optical pulses within the neutron-detecting material couple into at least one fiber. This positions the neutron absorption in an x-y plane.
Benefits•Allows materials previously unavailable for neutron detection to be used
•Expands the range of scintillating particles that can be used for detection (limited only by compatibility with current sol-gel methodology)Applications and Industries•Two-dimensional position-sensitive neutron detection
•Neutron detection and counting in health physics and health industry applications
•Detection of fissile and fissionable material in security applicationsMore InformationInventor Point of Contact

|Title and Abstract||
Neutron detector using lithiated glass-scintillating particle composite
A neutron detector composed of a matrix of scintillating particles imbedded in a lithiated glass is disclosed. The neutron detector detects the neutrons by absorbing the neutron in the lithium-6 isotope which has been enriched from the natural isotopic ratio to a commercial ninety five percent. The utility of the detector is optimized by suitably selecting scintillating particle sizes in the range of the alpha and the triton. Nominal particle sizes are in the range of five to twenty five microns depending upon the specific scintillating particle selected.
