X-ray fluorescence spectroscopy is a widely used and extremely sensitive analytical technique for qualitative and quantitative chemical analysis. Superconducting Transition Edge Sensor (TES) microcalorimeter detectors have now been developed that achieve an energy resolution of 2 eV for 1.5 keV X-rays, which is sufficient to enable the measurement of the small shift of the X-ray line position that ...

Inertial navigation systems (INS) are a critical asset to the DoD in environments where GPS is either denied or unavailable. At the heart of these systems are precision acceleration and rotation sensors. Recently, MEMS-based accelerometers have found wide

In the proposed effort, we will leverage this extensive experience and capabilities to realize a frequency agile mmW radiometer that can cover the range of DC-110 GHz and can be scaled to DC-200 GHz under Phase II. Ours is a photonic system that multiplies and up-coverts a low-frequency reference signal onto an optical carrier (laser) using EO modulation, then uses the modulation sidebands to inj ...

iBeam Materials practices a technology for fabricating large-area crystalline-aligned coatings (films) on polycrystalline substrates using ion-beam assisted deposition (IBAD). Crystalline-aligned films of MgO are routinely made using IBAD with grain alignment of a few degrees. This process was originally developed for manufacturing of high temperature superconductor wire in km lengths. We propose ...

We propose to design, build and analyze Massively Redundant Electromechanical (MREM) Actuators based on multilayer, electrostatic motors. The key element is combining many wafer-scale components to produce a highly reliable large-scale actuator. The device consists of many individual actuator modules which allows it to be scaled up or down in size, force and power. Each module contains interleave ...

AstroPower proposes to develop gallium phosphide (GaP) ultraviolet (UV) sensors for engine combustion control. The UV spectra from the free radial combustion components correlates with combustion effectivity in terms of predetonation, and provides a real time basis for central control of excess air ratio, internal combustion temperatures, and other fuel injector parameters. A system for the engine ...

Computer and engine studies demonstrated a 100% increase in diesel engine power with the use of 31% oxygen enriched air (OEA) versus standard 21% oxygen air. Additional benefits from OEA include: (1) improved fuel efficiency, (2) compatible with lower grade (volatility) fuels, (3) reduced CO and hydrocarbon emissions, (4) enhanced lean burn capability, (5) smoother less noisy operation, (6) better ...

Parallel computers have been widely available for several years but have yet to fulfill their promise despite the potential for greater scalability and lower cost/performance. While interest in parallel computing systems remains high, widespread proliferation and acceptance of these systems has not occurred. The basic problem facing MPP users is a lack of portable and scalable programming systems, ...
