Publication number: 20160216398Abstract: A second stage screening system configured to resolve a threat alarm detected in a cargo by a first stage screening system. The second stage screening system includes layers of first muon detectors placed above the cargo to detect a first coordinate and an angle of incidence of incoming muons and layers of second muon detectors placed below the cargo to detect an actual coordinate and an actual angle of exit of the incoming muons. The first and second detectors measure a momentum of the incoming muons. A processing unit receives threat sensitivity vectors determined from the first stage, operates a cargo positioning system that centers a high-Z threat within the cargo, relative to the first and second muon detectors, and analyzes the momentum and a distribution of deflection angles between the angles of incidence and exit to resolve the threat alarm.Type: ApplicationFiled: February 4, 2016Publication date: July 28, 2016Inventors: Joseph Bendahan, Edward James Morton, David Yaish, Yossi Kolkovich, Jacques Goldberg

Patent number: 9329285Abstract: 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.Type: GrantFiled: January 14, 2015Date of Patent: May 3, 2016Assignee: Rapiscan Systems, Inc.Inventors: Tsahi Gozani, Michael Joseph King, Donald Bennett Hilliard, Joseph Bendahan, William Gerhardus Johannes Langeveld

Publication number: 20160097877Abstract: The present specification discloses systems and methods for integrating manifest data for cargo and light vehicles with their X-ray images generated during scanning. Manifest data is automatically imported into the system for each shipment, and helps the security personnel to quickly determine the contents of cargo. In case of a mismatch between cargo contents shown by manifest data and the X-ray images, the cargo may be withheld for further inspection. In one embodiment, the process of analyzing the X-ray image of the cargo in conjunction with the manifest data is automated.Type: ApplicationFiled: June 15, 2015Publication date: April 7, 2016Inventors: Shehul Sailesh Parikh, Balamurugan Sankaranarayaran, Jeffrey Bryan Abel, Siva Kumar, Joseph Bendahan

Publication number: 20160018538Abstract: The present specification describes systems and methods for the simultaneous detection of radioactive materials such as neutrons, muons and gamma rays based on thin gap chamber technology. A thin-gap chamber (TGC) is disclosed having a thermal neutron absorber material, such as 10B4C or 10B8C, which interacts with neutrons to emit heavy particles. The heavy particles, in turn, interact with the gas present in chamber to produce ionization that is converted into a measurable signal. The TGC is embedded in a neutron moderating medium. The detector systems are fabricated from commercially available construction materials and are easy to manufacture at a reasonable cost when compared to conventional He-3 neutron detector systems.Type: ApplicationFiled: January 8, 2015Publication date: January 21, 2016Inventors: Joseph Bendahan, Michael King
