(2) Resolution and pixel density… more
Abstract:Regardless of the final choice of magnet technology and optics layout, most collider schemes will have a finite crossing angle with which bunches collide, resulting in a reduction in luminosity. It is accepted in the community that crab cavities can be developed to reduce this relative angle and… more
Abstract:Modern synchrotron light sources have come to rely upon superconducting radio frequency (SRF) acceleration to achieve high luminosity. To date, the workhorse in this area has been the SRF system developed by Cornell in the mid-1990¿s for the CESR-B machine. However, as the quest for higher… more
Abstract:High-repetition-rate (>1 MHz), high-bunch-charge (up to 1 nC) electron sources will be critical components of next generation light sources, which will be needed to upgrade DOE user facilities. These electron sources must possess high gradients at the cathode surface to provide for low emittance… more
Abstract:Future third generation light sources, such as the NSLS-II synchrotron light source proposed for Brookhaven National Laboratory (BNL), push the operating current and subsequent beam power to levels beyond the capabilities of single CESR-B/KEKB cavities. The proposed light source requires 500mA and… more
Abstract:The International Linear Collider (ILC) represents the next great undertaking for the worldwide high energy physics community. In addition to technical challenges posed by the project, the political realities demand a reduction in the cost of the components of this massive facility. The helium… more
Abstract:This Small Business Innovation Research Phase I research project involves the development of inexpensive, reconfigurable force-reflective telerobotic manipulators. Incorporating dexterous manipulators onto available mobile robotic platforms greatly expands the capabilities and usefulness of the… more
Abstract:This Small Business Innovation Research (SBIR) Phase II project will assess the performance of autonomic-healing concrete asphalt through large-scale testing. Each year, about 500 million tons of hot mix asphalt is produced in America, with an average price of $80 per ton. Compared to concrete, hot… more
Abstract:DESCRIPTION (provided by applicant): There is a growing body of evidence that implicates the protein kinase Pim-1 as a major driver of prostate cancer progression, and perhaps response to chemotherapy. Pim-1 is overexpressed in early prostate intraepitheli

Abstract:The overall objective of the proposed research is to design, develop and demonstrate fluidic actuator arrays for aerodynamic separation control and drag reduction. These actuators are based on a compact design of low mass-flow fluidic oscillators that produce high frequency (1-5 kHz) sweeping jets.… more
Abstract:Both pyrolysis and oxidation steps have been considered as the key solid waste processing step for a Controlled Ecological Life Support System (CELSS). Pyrolysis is more amenable to handling mixed solid waste streams in a microgravity environment, but produces a more complex product stream.… more
Abstract:Under sponsorship of the Air Force SBIR program, the small business Advanced Fuel Research, Inc. (AFR) is developing an innovative sensor system to map the surface temperature of thermal barrier coated (TBC) turbine blades during operational testing of advanced military jet engines. Temperature… more
Abstract:Gas turbine engine development requires sensors to measure gas path properties in engines during ground testing. The data collected with these sensors are critical to the development of advanced engines with high performance, high efficiency, and low emissions. While instrumentation is available to… more

There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
