Abstract :
We are working on a revolutionary scintillating plastic material in the form of a fused fiber structure. The material has different responses to fast neutrons, gamma rays and thermal neutrons. Energy deposited in 3-D voxels will be recorded using SiPM technology. This material development is directed towards the urgent need for high resolution imaging of both fast fission neutrons and gamma rays, and detection of thermal neutrons. This multi-functionality is driven by the demanding needs to detect various types of special nuclear material (SNM). This unique scintillating material is the basis for an imaging camera capable of performing, for the first time, all three of the above fundamental measurements for passive detection of SNM and RDDs. It does this with increased signal/background by order of magnitude or more. A Nanoptics, Inc. patent application is being submitted for the unique material and structure of the camera.
