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 ...

The key innovation of the proposal is a novel, fast and accurate, algorithm (patent pending) to simulate substrate effects, in particular single event transients (SETs), in semiconductor circuits. This new method opens up a new capability for circuit designers to study a large set of substrate and layout related effects using simulation, helps them to make good choices regarding circuit design and ...

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 ...

We propose to deliver a system prototype based on the Adaptive Storage Network (ASN) architecture developed in Phase 1 of the SBIR, in order to demonstrate that a fully-distributed self-organizing approach can meet the needs of scalable storage repositories for the NGA and other governmental and large-enterprise infrastructures. The goal of this project is to make data simply and transparently acc ...

Alameda Applied Sciences Corporation (AASC) proposes to develop an all-solid-state, compact, portable, multi-gigawatt poer modulator for electron and ion beam diodes, high power microwave and x-ray sources. This modulator is based on Inductive Energy Store (IES) using an array of Diamond Opening Switches for power compression. Because power amplification using IES requires a much smaller volume ...

Alameda Applied Sciences Corporation (AASC) proposes to develop a new type of interferometer that is compact and portable and can be used to make in-situ measurements of gases and plasmas. This interferometer uses polarization maintaining optical fibers and diode lasers to duplicate the capabilities of existing Mach-Zender interferometers that use dicrete optical elements such as mirrors, lenses ...

THERE IS AN ESTABLISHED NEED FOR A SIMPLE ROBUST TRANSDUCER TO MEASURE PARTICLE VELOCITY IN SEVERE BLAST AND SHOCK ENVIRONMENTS SUCH AS NUCLEAR AND HIGH EXPLOSIVE TESTS. A GAGE CONCEPT IS PROPOSED FOR DEVELOPMENT, BASED ON THE PROVEN MEASUREMENT PRINCIPLES USED IN THE HIGHLY SUCCESSFUL DX GAGE, BUT RECONFIGURED MECHANICALLY AND ELECTRICALLY TO WITHSTAND THE HARSH SHOCK ENVIRONMENTS. THE CONCEPT RE ...

HIGH RANGE (200,000 G) ACCELEROMETERS ARE THE ONLY TRANSDUCERS THAT PROVIDE THE REQUIRED LONG-TERM DATA IN THE ENVIRONMENTS OF INTEREST TO THE BLAST AND SHOCK COMMUNITY. THESE GAGES HAVE A VERY LARGE DYNAMIC RANGE AND NOISE OFTEN MASKS THE LATE TIME (BUT EXTREMELY IMPORTANT) DATA. WE PROPOSE TO DEVELOP A CLOSE COUPLED LOGARITHMIC GAIN SIGNAL CONDITIONING SYSTEM THAT WILL CORRECT THE LATE TIME NOIS ...

CURRENT NUMERICAL COMPUTATIONS TO DESCRIBE NUCLEAR GROUND SHOCK ENVIRONMENTS, NUCLEAR CRATER FORMATION, IMPACT DYNAMICS AND PENETRATION MECHANISMS PRESENTLY EMPLOY EULERIAN-BASED FINITE DIFFERENCE CODES BECAUSE OF THEIR ABILITY TO MODEL THE MASS FLUX PHENOMENA IN TRACKING MATERIAL MOVEMENT THROUGH THE DISCRETIZED SPACE. THE FINITE DIFFERENCE CODES SUFFER IN COMPARISON TO FINITE ELEMENT CODES, HOWE ...

DNA PRESENTLY SPONSORS EXPERIMENTAL INVESTIGATIONS OF NON-DEAL AIR BLAST AT ERNST MACH INSTITUTE (EMI), AND MODELING EFFORTS AT NSWC. PRESENTLY, THE EXPERIMENTAL RESULTS, IN THE FORM OF MACH-ZEHNDER INTERFEROMETER, BEING BOTH FUNCTIONS OF TEMPERATURE AND CONCENTRATION, CANNOT BE REDUCED FOR COMPARISON WITH THE COMPUTER RESULTS. IT IS PROPOSED THAT THE NECESSARY CAPABILITIES BE DEVELOPED TO FACILIT ...
