Nuclear threat detection
First Claim
Patent Images
1. A detector for detecting nuclear radiation threats, the detector comprising:
- a plurality of elongate scintillator segments arranged in a side by side array;
at least one pair of light sensors optically coupled to ends of each of the elongate scintillator segments such that they receive light from scintillations produced in the scintillator segments and generate electrical signals responsive thereto; and
a controller that identifies a plurality of scintillations as emanating from a single incident particle based on a time window within which they fall and their spatial proximity within the detector.

46. A detector for detecting nuclear radiation threats, the detector comprising:
-
a plurality of elongate scintillator segments arranged in a side by side array; and at least one pair of light sensors optically coupled to ends of each of the elongate scintillator segments such that they receive light from scintillations produced in the scintillator segments and generate electrical signals responsive thereto; wherein the plurality of elongate scintillators segments form a detector having a front face, wherein the front face is not flat, and wherein alternating portions of the front face extend further front than other portions. - View Dependent Claims (47, 48)

49. A detector for detecting nuclear threats, the detector comprising:
-
a plurality of elongate scintillator segments arranged in a side by side array; at least one pair of light sensors optically coupled to ends of each of the elongate scintillator segments such that they receive light from scintillations produced in the scintillator segments and generate electrical signals responsive thereto; and a controller that receives said signals and determines whether time spaced scintillations that occur in different scintillator segments are from interactions resulting from a same or a different photon entering the detector.
