Inventor： Tsahi Gozani , Michael Joseph King , Donald Bennett Hilliard , Joseph Bendahan
IPC: G01T1/203
CPC classification number: G01T3/06 , G01T1/167 , G01T1/2008 , G01T1/203 , G01T3/008 , G01V5/0075 , G01V5/0091 , H01J43/08 , H01J43/30
Abstract: The present invention provides a gamma-neutron detector based on mixtures of thermal neutron absorbers that produce heavy-particle emission following thermal capture. In one configuration, B-10 based detector is used in a parallel electrode plate geometry that integrates neutron moderating sheets, such as polyethylene, on the back of the electrode plates to thermalize the neutrons and then detect them with high efficiency. The moderator can also be replaced with plastic scintillator sheets viewed with a large area photomultiplier tube to detect gamma-rays as well. The detector can be used in several scanning configurations including portal, drive-through, drive-by, handheld and backpack, etc.
