Spectrum Photonics will utilize our 20 years of experience in developing and employing multi-spectral disturbed earth sensors to develop a vehicle-mounted, low-cost mobile footprint detector. To meet the specifications described in the SBIR topic, our team will develop a multi-spectral long wave infrared sensor that will exploit the restrstrahlen effect for the silicate-based soils that dominate ...

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 ...

To meet the critical security needs of the Department of Homeland Security and others, we propose two methods for providing a secure root of trust for mobile devices. One method is designed to integrate as easily into existing systems, while the other requires deeper integration but provides correspondingly stronger security. The keys to our work are practicality and integration: practicality to e ...

Software development faces many challenges as high-performance computing (HPC) moves towards exascale: scalability, programmability, performance portability, resilience, and energy efficiency. To tackle these challenges, fundamental shifts in the basic execution models and programming models employed by HPC software are required. In particular, commonly used linear algebra libraries performance s ...

Next generation reactor concepts cater to a common goal of providing safer, longer lasting and economically viable nuclear power plants. Developing radiation damage resistant materials for both in- core and out-of core applications is a critical component of these next generation power plants. Testing these novel materials requires an intense neutron environment. A commonly used tool for testing n ...

Environmental sensor networks capable of taking data quickly enough to capture minutescale fluctuations and durable enough to capture these data for entire seasons provide essential information for studying the seasonal and annual effects of microbial activity across complete ecosystems. Distributed sensors for subsurface dissolved oxygen (DO) concentration measurement are of particular interest b ...

Researchers at JBEI have developed a pretreatment technology using ionic liquids that efficiently extracts sugars from a combination of mixed feed stocks. Any ionic liquid used for biomass pretreatment or cellulose hydrolysis by thermostable cellulose may be used. Until now, no known technology could efficiently pretreat and liberate sugars from mixed feedstock streams. The JBEI technolo ...

Three different modalities of radiation sterilization currently exist: gamma-ray sterilization, electron beam sterilization, and x-ray sterilization. One of the most common ways to sterilize goods is with gamma producing radioactive sources, most commonly Co-60 and Cs-137. Long-term possession of these sources is undesirable due to security concerns, Nuclear Regulatory Commission over ...

Many planned nextgeneration experiments in high energy physics, astroparticle physics, and nuclear physics need a plethora of photon detectors with singlephoton sensitivity, large dynamic range, and accessibility throughout experiment lifetime. These requirements constrain the sensor: low sensitivity against temperature and bias fluctuations; very compact; very robust; cheap; insensitive to magn ...

The main focus of photonuclear physics has always been investigation of the internal spatial and spin structure of the nuclei and nucleons. While high energy photons (over 100 MeV) are used most often to probe the nuclear structure and look deep into the nucleus, intermediate energy (1-40 MeV) photonuclear reactions can also provide significant information via nuclear resonance fluorescence and sp ...
