Aerosol particles have important impacts on visibility, acid deposition, climate, and human health, although large uncertainties remain in quantifying their chemical composition and atmospheric transformations. A large fraction of the anthropogenic aerosol is generated from energy-related activities, and organic compounds are known to constitute a significant fraction of ambient aerosol mass. Re ...

The project is developing a new sensor technology that can measure carbon dioxide levels with precision that matches or exceeds the state-of-the-art performance, but will reduce the price dramatically, and will for the first time enable instruments deployed in remote locations to operate unattended for long periods of time. A laboratory prototype was designed, constructed, and demonstrated. It exc ...

U.S. automakers have invested significant resources in the research and development of hydrogen fuel-cell vehicles. However, to enable their widespread use, an additional major investment will be required to construct an infrastructure for hydrogen production and delivery to fueling stations. In order to facilitate this transition, the DOE has recommended that high-pressure hydrogen generation fo ...

Greenhouse gas (GHG) emissions are primary drivers of global climate change. Hence there is a crucial need to quantify their sources and sinks. A powerful method to constrain source and sink strengths is the analysis of the relative proportions of isotopic variants of GHG’s in atmospheric samples like those collected globally by NOAA’s Cooperative Air Sampling Network. Measurements that are ca ...

While substantial advancements have been made in realizing tube based large area detectors such as the Large Area Picosecond Photo-Detector (LAPPD), there is widespread agreement in the cathode community that a higher QE bialkali cathode is possible, and that the present understanding is largely-recipe driven without the adequate control or understanding to achieve the previously observed high yie ...

Electronic systems have increasingly high thermal demands that need improved cooling solutions that are reliable, light weight, and low cost. From computer data storage centers and electric vehicles to on-detector electronics used in nuclear physics instruments, a liquid-cooled micro-channel thermal control system will help improve the performance and reliability of these electronic systems. A new ...

During the Phase I program, Aurora conducted a comprehensive survey of potential platforms that included government owned and furnished UAVs and manned aircraft as well as Aurora’s Centaur Optionally Piloted Aircraft (OPA). The survey concluded, in part, that UAVs offer a significant improvement in data collection capability when compared to manned aircraft that are currently fielded by NOAA. ...

One of the proposed next generation Intensity Frontier experiments is Mu2e. Mu2e will directly probe the Intensity Frontier as well as aid research on the Energy and Cosmic frontiers with precision measurements required to characterize the properties and interactions of new particles discovered at the Intensity Frontier. In order to reach its science goals, detector upgrades are required. A key ap ...

Industrial processes such as glass production burn huge quantities of natural gas. Burner settings are often set with large error margins to avoid producing pollution. They are also frequently set

Thyratrons are common components of many klystron modulators. Requiring replacement approximately every 10,000 hours as well as periodic maintenance and adjustment, they represent a high recurring cost for accelerators (and other installations), which are designed to operate for much longer periods of time. A solid-state replacement for these thyratron will improve performance, decrease operating ...
