Electron accelerators that produce high duty cycle electron beams with beam energies up to 9 MeV are essential for use in practical Nuclear Resonance Fluorescence and EZ-3DTM imaging technologies. While isotopic identification of shielded materials is now possible via these technologies, it is still necessary to achieve accelerator portability, compactness and reasonable cost of ownership to make ...

The goal of this program is to produce large-volume composite scintillators using smaller, cheap-to-produce CLYC crystals, as gamma-neutron radiation detectors, for use in portable detection equipment for homeland security, and monitoring of nuclear material accountability.

Implementing continuous nuclear and radiological monitoring systems that support automatic detection and tracking of potential nuclear threats is\ntraditionally associated with a high operational burden. Sensors are typically monitored by dedicated personnel, who must investigate detection events\nin a timely manner. High nuisance alarm rates can rapidly overwhelm already taxed law enforcement per ...

The goal of this program is to fabricate and demonstrate a Spectroscopic Personal Radiation Detector (SPRD) based on semiconductor sensors, TlBr for gamma detection and LiInSe2 (LIS) for neutron detection. These compact SPRDs will meet or exceed ANSI 42.48 requirements at a low cost. The SPRDs will also have directional capabilities resulting in faster localization of the radiation threat. In phas ...

RMD is developing a semiconductor base Spectroscopic Personal Radiation Detector (SPRD). The gamma detection is be based on TlBr and the neutron detection on LiInSe (LIS) semiconductors. These detection technologies have been under development in RMD for several years with the DHS and other government agencies support. The primary technological benefit of semiconductor detectors for gamma detectio ...

Proliferation of the weapons of mass destruction such as nuclear weapons is a serious threat in the world today. Preventing the spread of nuclear weapons has reached a state of heightened urgency in recent years, especially since the events on September 11, 2001 and its aftermath. One way to passively determine the presence of nuclear weapons is to detect and identify characteristic signatures of ...

In the proposed program, we plan to investigate novel semiconductor neutron detectors based on the wide bandgap lithium containing compositions LiGaSe2, LiGaTe2, LiInS2, and LiInSe2. The goal of the program is to produce detector quality crystals and to demonstrate efficient thermal neutron detection, with the possibility of providing neutron gamma discrimination. We will examine the synthesis and ...

Neutron detection is one of the methods used in revealing illicit nuclear materials. Currently, there is an ongoing search for new and better neutron detectors prompted by anticipated shortages of He-3 that is used in many of the current detection systems. This effort proposes and investigation and development of a new thermal neutron and gamma scintillator. The scintillator belongs to already pro ...

BlueRISC's proposed solution provides a fundamentally new approach to automated embedded software/firmware analysis relying on a novel cross-binary/firmware differential exploitability analysis framework. The solution is able to identify newly added potentially exploitable paths associated with zero/n-day vulnerabilities, characterize new functionality with respect to its potentially malicious nat ...

Proliferation of the weapons of mass destruction such as nuclear weapons is a serious threat. Prevention of their spread has reached a state of heightened urgency in recent years. One of the ways to passively determine the presence of nuclear weapons is to detect and identify characteristic signatures of highly enriched uranium and weapons grade plutonium. Neutrons and gamma rays are two signature ...
