The development of large-area (m2) photodetectors with time resolutions of picoseconds (10-12 seconds) and submillimeter space resolutions would open new opportunities in collider detectors at the Energy Frontier, kaon and neutrino experiments at the Intensity Frontier, photon detection in detectors at the Cosmic Frontier, and applications with a large impact on societal issues such as low-dose-r ...

An improved method is needed for the detection of radiological materials for nuclear nonproliferation and safety. Current techniques using laser-induced breakdown spectroscopy (LIBS), while robust, are limited in range due to pulse energy and diffraction. Furthermore, atmospheric broadening of the spectral lines reduces the sensitivity of the detection scheme, such as optical emission spectroscopy ...

Solid-state power electronic circuits that incorporate switching devices such as IGBTs, IGCTs and MOSFETs can now operate at voltages as high as 3KV to 6.0+KV with peak currents of 0.5-6.0+KA. Modulators built with various topologies require high voltage, energy storage capacitors, that can operate at the same voltage and current as the switching devices. Presently such capacitors a ...

A high energy density capacitor with superior life and reliability will be developed that is a key component of power semiconductor inverter circuits, used in automotive hybrid and electric vehicles, rail transit, wind power generators, photovoltaics, and transportable energy storage systems for grid applications.

Vibrationally resonant sum-frequency generation (SFG) spectroscopy is a second order nonlinear optical technique that features high chemical selectivity and a set of selection rules that makes it an ideal complement to coherent Raman scattering (CRS) as an imaging tool. Attempts have been made to construct high-resolution, high speed SFG microscopes, but to date both the resolving power and image ...

With no moving parts other than a syringe pump, this tool will allow for the reliable measurement of flow rate as a function of depth within a geothermal wellbore and thus provide for improved reservoir management. By improving wellbore flow measurements, predictions of well performance will dramatically improve and EGS energy production will become more reliable and more cost effective.

ABSTRACT: After original equipment manufacturing (OEM) support and replacement of gas turbine engine components expires, sustainment of aging Air Force fleets are required to maintain continued fleet operability. Additive manufacturing to repair metal engine components which meets Federal Aviation Administration (FAA) part manufacturing approval (PMA) is a viable approach to produce components th ...

ABSTRACT: Both commercial and military aircraft are being flown/utilized for extended operational time. The aircraft cumulative flight hours often times extends the original design limits. Each different aircraft manufacturer calculates aircraft fatigue and damage using different techniques. A more accurate prediction of remaining life and inspection interval for an individual aircraft is require ...

ABSTRACT: Cache memory is normally built with Static Random-Access Memories (SRAM ) and are necessary for many applications, including sensors, hardware based radio station, wireless systems, instrumentation, video, and power. These applications are often used in harsh environments including the nuclear, space, and military markets. These radiation environments magnify the difficulty of designi ...

ABSTRACT: This offer proposes a set of activities to provide an innovative, modular, cost-effective and easily deployable AFSCN simulator. The derived solution will support satellite Factory Compatibility Test (FCT) for satellite programs utilizing the AFSCN. Using open architecture, open standards, COTS software and hardware, and a modular approach to develop a largely software-based simulatio ...
