Electric vehicles, hybrid electric vehicles, and plugin hybrid electric vehicles (EVs, HEVs, and PHEVs) are emerging technologies that can significantly reduce petroleum usage in the transportation sector. Widespread adoption of electricdrive vehicles will lower automobile operation costs and can significantly decrease emissions of greenhouse gases. However, for these technologies to be successful ...

In atmospheric aerosol research, size-distributed aerosol samples are often collected with airborne instrumentation, but are not analyzed in any manner until after they are brought to a laboratory on the ground. The information thus obtained is averaged for all the locations covered during the mission. A novel technology is being developed in this project to constantly measure the size-distributed ...

The negative-electron-affinity (NEA) photocathodes which produce polarized electrons are a vital component of electron accelerators such as that at DoE Jefferson Lab and the Stanford Linear Accelerator Center (SLAC). Future systems, such as the International Linear Collider (ILC), will require a polarized electron beam intensity at least 20 times greater than produced by strained GaAs, which is u ...

MSP is introducing in this proposal a practical approach to a family of cascade impactors capable of real-time measurement of the size-distributed mass concentration of particles in the atmosphere. Further, because of the high sensitivity of the proposed mass transducers, these impactors will also provide nearly instantaneous information about the influence of water vapor on the size distribution ...

Photocathodes with spin-polarized electron emission are used in physics research. Current photocathodes offer high polarization, but low total currents, and have limited lifetime. Research involving these polarized electrons would be more productive if a higher electron current were provided. This program seeks to increase the delivered polarized electron current from the photocathodes by adding i ...

For several decades photomultiplier tubes (PMTs) have been the main technology for sensitive and low noise detection of photons in many high energy physics experiments. However, compared to solid-state photodetectors, PMTs are bulky, fragile, expensive, and need to be shielded from high magnetic fields and high pressures, which severely limit their application for future DOE projects. Hence, th ...

The negative-electron-affinity (NEA) photocathodes which produce polarized electrons are a vital component of electron accelerators such as that at the Stanford Linear Accelerator Center (SLAC). Future systems, such as the International Linear Collider (ILC), will require a polarized electron beam intensity at least 20 times greater than produced by strained GaAs, which is used in the current gene ...

Salo IT Solutions, Inc. will design and implement the Wide-area, Environmental Sensing and alterTing network (WESTnet) protocols, a next-generation suite of wireless network protocols that will provide enhanced services for hydrologic warning systems and other large-scale, wide-area environmental monitoring activities. The WESTnet protocols will offer significant functionality over that available ...

Current technology for detecting long wavelength and very long wavelength infrared light, such as mercury cadmium telluride-based sensors, suffers from deleterious characteristics such as high noise and high cost. Creating detectors that operate in this wavelength range that reduce noise and cost will foster further implementation into remote sensing systems. SVT Associates proposes an innovative ...

The negative-electron-affinity (NEA) photocathodes which produce polarized electrons are a vital component of electron accelerators such as that at the Stanford Linear Accelerator Center (SLAC), which is used in the current generation of photocathodes. Quantum efficiencies thus far are on the order of 1%, meaning only 1% of the photons hitting the photocathode result in the emission of an electro ...
