In response to a DTRA need, Physical Optics Corporation (POC) has developed a new, low-cost Advanced Radiation Detector (ARAD) and a process to produce it. ARAD is based on thallium-doped cesium iodide scintillator, sensitive to gamma and X-ray energies up to 1 MeV with 3% resolution, and fully compatible with existing mass production technologies. In Phase I POC successfully completed the ARAD ...

With the advent of high-density low-power sub-20nm technology processes and circuits with tens-of-billions of transistors, radiation-induced single-event effects present a new set of design challenges for terrestrial applications. Developing reliable single-event effect resilient microelectronics in these modern technology nodes is a resource and time-intensive endeavor that further requires valid ...

Presently, commercial and government radiation test facilities do not have convenient, reliable calibration systems for routine, day-in, day-out checks on x-ray and neutron detectors or their filter arrays. Lack of such calibration systems compromises the quality of the testing, and leads to wasted time and manpower resources used to resolve the ensuing uncertainties. We are developing a compact, ...

Alameda Applied Sciences Corporation (AASC) proposes to replace the anode posts of a soft x-ray z-pinch with an azimuthally symmetric shell of high density, low atomic number gas. Once ionized, the gas column carries the current and eliminates particulate debris that is otherwise generated by the return rods. The gas shell also absorbs unwanted UV and hence eliminates the first Li foil filter of t ...

Purpose: This project team will fully develop and test Woot Math Polls, a formative assessment dashboard that converts student math work into data-driven insights to inform teacher instruction and student learning in middle and high school algebra classrooms. Research has marked a decline in math achievement around the time students take algebra in middle school. Technological innovations that pro ...

We propose to develop a battery powered portable monitoring system capable of collecting and analyzing gamma spectra for specific radionuclides in the field. The system will consist of a high resolution cadmium telluride array detector and a small multichannel analyzer and data logger. The proposed monitoring system builds upon the design of the Ludlum Model 2350 Data Logger which is quite rugge ...

AT PRESENT, COMPUTERS ARE AVAILABLE WITH ENORMOUS QUANTITIES OF CORE STORAGE AND EXTREMELY FAST COMPUTATIONAL CAPABILITIES AS COMPARED WITH COMPUTERS JUST A FEW YEARS OLD. IN THE NEXT YEAR OR TWO, EVEN MORE DRAMATIC INCREASES IN MEMORY AND COMPUTATIONAL SPEED WILL BECOME AVAILABLE. OF IMPORTANCE TO DNA/RAAE IS THE FACT THAT THESE NEW COMPUTERS WILL ALLOW THE CALCULATION OF HIGH ALTITUDE NUCLEAR WE ...

HORIZONS TECHNOLOGY, INC., (HTI) PROPOSES TO EXAMINE THE BENEFITS OF APPLYING HYPERTEXT, EXPERT SYSTEM, AND MICROCOMPUTER TECHNOLOGIES TO INCREASE THE EFFECTIVENESS OF SCIENTIFIC COMPUTING AND COMPUTATIONAL AIDS (CAP) AND BY INCREASING THE USABILITY OF REFERENCE DOCUMENTATION DESCRIBING COMPLEX NUCLEAR WEAPON EFFECTS PHENOMENOLOGY. A HYPERTEXT DOCUMENT ALLOWS THE USER TO EASILY ACCESS DIFFERENT TY ...

FOR TESTING OF ELECTRONICS IT IS IMPORTANT HOW THE X-RAY ENERGY SPECTRUM FROM A BREMSSTRAHLUNG FLASH X-RAY SIMULATOR CHANGES WITH TIME. HOWEVER, ONLY THE TIME-INTEGRATED SPECTRUM CAN BE MEASURED CONVENIENTLY, USING DIFFERENTIALLY FILTERED TLD'S. THIS PROPOSAL IS TO DEVELOP A TIME-DEPENDENT VERSION OF A DIFFERENTIALLY FILTERED SPECTROMETER, BY REPLACING THE TLD'S WITH PHOTOCONDUCTIVE ELEMENTS SUCH ...
