SixPoint Materials will create low-cost, high-quality vertical gallium nitride (GaN) substrates using a multi-phase production approach that employs both hydride vapor phase epitaxy (HVPE) technology and ammonothermal growth techniques to lower costs and maintain crystal quality. Substrates are thin wafers of semiconducting material needed for power devices. In its two-phase project, SixPoint Mate ...

Soraa will develop a cost-effective technique to manufacture high-quality, high-performance gallium nitride (GaN) crystal substrates that are better than today’s GaN crystal substrates, which are expensive and prone to defects. Soraa will also develop pathways to large-area GaN substrates that can handle power switch applications. Substrates are thin wafers of semiconducting material needed for ...

In the post 9/11 security environment, rapid cargo inspection has become a high priority. Cargo scanning using either radiographic imaging or active interrogation for Special Nuclear Material (SNM) requires high energy and high intensity x-rays. High intensity x-ray sources are especially important for active interrogation techniques such as photo-fission, delayed neutron & gamma measurements, p ...

Computer simulations have the potential to improve the development x-ray-based explosive detection equipment. Despite the number of available simulation tools, no existing tool meets the needs of the explosive detection community. This is due to (1) the flexibility required to model the range of objects, physical processes, and system geometries used in explosive detection, and (2) the usability ...

The proposal describes a solution offered by SARA, Inc. in response to the problem of developing a Laser Exposure Monitoring System (LEMS) capable of directly measuring laser exposures relative to Maximum Permissible Exposure (MPE) limits and establishing the boundaries of the Nominal Hazard Zones (NHZ). The approach uses multiple sensors to measure the irradiance and spectrum of the laser irradia ...

KWJ proposes to develop an ultra-low power and low cost, handheld device for monitoring of post-fire air quality, including DHS target toxic gases, combustion gases, CO2, LEL and particular matter (PM). The proposed device will significantly improve the current air monitoring instrumentation of protecting fire responders from hazard post-fire environment. Current multi-gas analyzers are not suitab ...

Mobile Non-Intrusive Inspection (NII) systems are advantageous as they can be deployed to where the greatest need exists, and they generally have small footprints, which is necessary in many locations. However the currently deployed mobile NII systems do not offer effective material discrimination, which is critical for shielded radiological/nuclear threat identification. This is because the curre ...

In response to DHS SBIR Topic H-SB013.1-004 we propose to investigate the development of a next-generation, tiered, inexpensive, light-weight, low-power, high-performance GPS emitter detection and localization system. The system will provide high-accuracy (high-sensitivity), real-time or near-real-time estimates of position, velocity, transmit frequency, and transmit power level of multiple, movin ...

Toyon has teamed with two utilities to survey the use of civilian GPS receivers in the energy and communication sectors, and to determine their vulnerabilities to intentional interference, including narrowband and wideband jamming, spoofers, repeaters, and RF-based 'software attacks.' As part of the survey, the characteristics and weaknesses of the deployed civilian receivers will be determined an ...

This SBIR Phase I project will investigate the possibility of using a network of low-cost, battery-powered radio frequency (RF) transceivers to detect, localize and track the movements of people illegally trying to enter the US borders through wooded areas. The system uses radio tomography (RT), i.e., the changes in radio signal strength (RSS) measurements on the static links of the network over t ...
