Abstract
A dual-particle imaging system of the present teachings provide for standoff, passive detection of special nuclear material. In some embodiments, the system comprises three detector planes that together are capable of imaging both photons and fast neutrons. The ability of the system to detect fast neutrons makes it more difficult to effectively shield a threat source.
Claims20
A detection system for detecting and imaging particles from a source, said detection system comprising:
- a first plane detecting a first particle contacting therewith and scattering said first particle, said first plane determining a first energy deposition of said first particle and a first time of contact with said first plane;
- a second plane detecting said first particle contacting therewith being scattered from said first plane, said second plane determining a second energy deposition of said first particle and a second time of contact with said second plane;
- and
- an actuation system coupled with at least one of said first plane and said second plane, said actuation system physically actuating a physical parameter of said at least one of said first plane and said second plane to effect at least one of said first energy deposition and said second energy deposition.
A detection system for detecting and imaging both neutrons and photons from a source, said detection system comprising:
- a first plane detecting a plurality of particles contacting therewith and scattering said plurality of particles, said first plane determining a first energy deposition of each of said plurality of particles and a first time of contact of each of said plurality of particles with said first plane, at least one of said plurality of particles is a neutron and at least another of said plurality of particles is a photon such that said first plane detects both neutrons and photons;
- a second plane detecting contact of said plurality of particles therewith being scattered from said first plane, said second plane determining a second energy deposition of each of said plurality of particles and a second time of contact of each of said plurality of particles with said second plane;
- and
- an actuation system coupled with at least one of said first plane and said second plane, said actuation system physically actuating a physical parameter of said at least one of said first plane and said second plane to effect at least one of said first energy depositions and said second energy depositions.
