Accuray bases this proposal on an X-ray generator, model DX500K, designed, built, and delivered to a major contractor in December 2008 as part of the DNDO-CAARS program. Accuray`s DX500K operates at single or dual energy modes of 6 MeV and 9 MeV and interleaves between 6 MeV and 9 MeV at 400 Hz. The pulse to pulse jitter is negligible -- a major performance factor in high Z detection. The system o ...

A pulsed neutron generator is proposed for the detection of special nuclear material. A recently developed RF-excited plasma neutron generator will be pulsed to produce the activating neutrons whose pulse length is 100 microseconds with a fall time of less than 1 microsecond. High pulse repetition rates and high peak neutron yields can be otained depending upon the RF generator used. Using the T-T ...

According to Department of Homeland Security (DHS), over 700 million pieces of baggage are screened for potential threats in the U.S. every year. Training methods for DHS screeners rely on conventional classroom instruction and on-the-job mentoring. By definition, a screener's work is challenging because the search for threats demands sustained, focused attention while reviewing many images with v ...

The U.S. Border Patrol is in critical need of improved surveillance for detection of people and vehicles illegally crossing the Southern Border, particularly in rural areas. AETC will conduct a Phase 1 feasibility study of acoustics-based surveillance and signal processing techniques to address the Southern Border problem. The overall system concept encompasses a network of low-cost acoustic senso ...

We propose to develop a methodology and test and evaluation framework for optimizing the remote capture of multimodal biometrics for automated screening and identification to the practical extent possible while the individuals are on the move, walking through an automated gate or corridor at the airport or a walkway across the border. In Phase one we will establish a set of multimodal biometrics ...

The Government is deploying a growing number of radiation detectors at U.S. borders, ports of entry and other key locations, intended to assist in the detection of a potential terrorist`s nuclear explosive device or radiological dispersal device. The most widely deployed radiation detector products today are radiation "pagers". Such products are unable to differentiate between natural radiation, l ...

The improved surveillance of radioactive sources used in hospitals, research centers, food irradiations plants and other fully legal and sanctioned industries is paramount to interrupt the terrorism value chain. This value chain relies on stealing radioactive sources from the legitimate before mentioned institutions to build radiological dispersal devices (RRD). Nowadays, radioactive sources are s ...

This Phase I proposal seeks to develop and demonstrate an improved first responder molecular analysis system based on a simplified methodology using aluminum oxide membrane (AOM) integrated sample preparation, amplification, and detection technology. This method has been shown to be faster, simpler, less expensive and more sensitive than existing methods. This proposal seeks to extend the applicab ...

Applied Physical Sciences Corp. will develop a distributed buoy detection system using an advanced acoustic receiver. The sonar array will consist of a vertical line of vector hydrophones to maximize gain against unwanted ambient noise and provide 20+nm detection ranges for targets of interest. Additionally the single vector vertical line array will provide target bearing and tracking data that ca ...

The focus of this proposal is to develop BioPhalanx a rapid, hand portable, robust detection system for multiplexed detection of bio-threats, in harsh environments. We have developed a new method of detection called Combinatorial Probe Analysis (CPA), which provides an exponential increase in detection reliability. This type of analysis will greatly reduce false positives and false negatives; in a ...
