The U.S. DOE Office of Environmental Management (EM) was created in 1989 to manage the cleanup of large areas of environmentally contaminated sites. Since the closure of many of these sites, U.S. taxpayers have spent about $220 billion at 74 cleanup sites. However, these sites were the smallest and most manageable sites to clean. There are still over 40 sites that are deemed as eno ...

In this work, a long lifetime (greater than 6 months) H- ion source capable of reliably delivering current greater than 10 mA will be designed. The immediate DoE need for this technology is a reliable DC H- ion source that will inject an ion beam into the proposed Project X particle accelerator at Fermi National Laboratory. There are several other basic science, medical, energy, and industrial ...

Many detectors - including solid-state particle detectors, microchannel plates, and photodiodes - output small current signals that require amplification and conversion to a voltage. Current-to-voltage converters (I/Vs) are widely utilized in experimental and commercial applications for this task. Numerous detection systems require wide bandwidth, ultra-low noise, high gain, and linear amplificati ...

Vacuum glazing has been on the market for over a decade, but its performance is poor, and its cost too high for wide adoption. Both issues stem from the use of a hard glass edge seal, which requires a high temperature manufacturing process, and which does not flex to accommodate outer pane contraction in winter weather. Lack of a low-cost, flexible seal has prevented successful commercialization o ...

The desire and benefit to improve the environment through the use of advanced electric drive vehicles is hampered by the high cost and associated manufacturing hazards associated with the manufacture of lithium ion batteries. The use of solvents in the lithium ion battery manufacturing process leads to high capital cost plants and subsequent recurring high manufacturing costs. Eskra Technical Pr ...

This project supports the advancement of electroforming capabilities to produce ultra-pure copper and provides opportunities for further progress in material growth science. Ultra high purity copper is a fundamental material used for a range of current and future fundamental nuclear physics programs such asMAJORANA. The capabilities that are expected to be developed under this project will address ...

Geologic carbon sequestration has become an effective technology for reducing atmospheric levels of CO2 by capturing emissions and injecting them into underground geologic formations where they can be permanently isolated. In order to assure that the CO2 is effectively sequestered for long periods of time and to reduce the likelihood of local environmental impacts, cost-effective methods are need ...

Although a number of new technologies are becoming available for environmental site remediation, the successful application of these technologies often depends on detailed knowledge of the site hydrogeology and the distribution of the contaminants. Recent research has demonstrated that the induced polarization (IP) method ¿ and, in particular, the spectral induced polarization (SIP) method ¿ m ...

The conceptual development of new components for use in accelerators, microwave devices, and other endeavors often starts with simplified models, typically in a reduced dimensional space. For radio frequency cavities and other beamline structures, where devices can often be reasonably approximated by rotationally symmetric analogues, a two-dimensional analysis allows for the rapid assessment of n ...

Understanding and suppressing dark current generation is an important part of designing a variety of high-field-gradient structures, including radio-frequency electron guns, slow-wave structures, and power feed systems. Presently, dark current modeling is needed for the design of the Machine Protection System for International Linear Collider Main Linac. In previous work, a prototype modeling ca ...
