Alameda Applied Sciences Corp proposes to develop a fast pulse, portable, fast neutron source to detect SNM in the field. Our source offers a less than 100ns neutron pulse with a repetition rate up to 100Hz. The goal is to develop a source with 1000hrs of continuous operation at greater than 1E8 n/s. The Phase II program will develop and validate a prototype for SNM detection. The commercial goal ...

Swimmer delivery systems, externally mounted on submarines, are subject to hydrodynamic flow and irregular wave-slap loads. These result in unsteady, alternating impacts that can damage exposed surfaces. It is important to track the cumulative stresses imposed on the fairing panels to provide operators with a sense of the remaining service life of the panels. Fairing Panel failure could be catastr ...

A pulsed neutron generator is proposed for the detection of special nuclear material. A recently developed microwave-excited plasma neutron generator will be pulsed to produce the activating neutrons whose pulse lengths vary from 100 microseconds to 2 ms with a fall time of less than 1 microseconds. We demonstrated that we can increase the peak yield as a function of either RF or microwave power, ...

The new material technology is based on 3D weaving for the reinforcement of buildings against both bomb blast and mitigation of the damage caused by flying objects. Four alternatives will be considered for the Phase I work dry 3D fabric, solid composite, sandwich core structures, and combination of these.

The recent emergence of the Silicon Drift detector (SDD), for use in Energy Dispersive x-ray Spectroscopy (EDS), has made possible x-ray event streams with input count rates in the range of 1-10 Mcps. Modern digital pulse processors are therefore required to run at fast time constants to achieve reasonable throughput; however, this causes significant coincidence artifacts to appear in the spectrum ...

We propose to demonstrate near infrared (NIR) InGaAs sensor arrays with 55% lower noise than arrays presently available to improve the sensitivity of current spectroscopy systems. The low noise performance will be enabled by the use of low-noise source follower per detector ROICs, which are also used in astronomy with HgCdTe for low noise measurements. With design improvements to current available ...

Special operation forces utilize C-130 aircraft that often operate in night/adverse weather, low-level, deep-penetration missions in contested or hostile environments. These low altitude missions result in higher risks to the crew and aircraft. AeroVironment proposes to leverage their current packaged and air-launched unmanned aerial vehicle (UAV) developments to design a self-contained, packaged ...

Detection systems for aeropathogens require the concentration of airborne particles from large volumes of air into small volumes of liquid. This proposal addresses this need through droplet encapsulation of airborne particles, with subsequent capture into a microliter-sized collection reservoir. Droplet encapsulation is accomplished through our company¿s proven, patented growth tube technology. T ...

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 ...

Technology research and development in such areas as next-generation atomic clocks, quantum information processing with trapped ions, and atomic spectroscopy is impeded by the lack of commercially available laser sources that meet the required specifications of wavelength tuning range, output power, frequency-stability and reliability. Arete Associates is developing frequency-stable Optically Pump ...
