The successful execution of the current high-capacity optical-networking environment, which supports supercomputing centers at the DOE national laboratories, requires adpative and finer-grained management/set-up of necessary bandwidth and low-delay paths between distributed applications. Whereas manual management techniques have been implemented in test beds and moderate-capacity networks, the ap ...

Workers performng deactivation and decommission activities in DOE facilities wear badges to measure exposure to beryllium. Currently, these badges are comprised of an air pump that draws in air to trap particulates on a filter cassette, which is then analyzed for beryllium. An ability to measure lower amounts of beryllium would be desirable because: (1) lower amounts of air could be sampled on ...

THIS PROJECT INVOLVES DEVELOPMENT AND VERIFICATION OF THE PERFORMANCE OF A NOVEL HEAT EXCHANGER OPERATING IN THE 98 TO 99 PERCENT THERMAL EFFECTIVENESS RANGE. HEAT EXCHANGERS FOR CRYOCOOLER APPLICATIONS USED IN HIGH ENERGY PHYSICS, REMOTE SENSING, ETC., FREQUENTLY REQUIRE THERMAL EFFECTIVENESS OF OVER 98%. THIS IS DIFFICULT TO ACCOMPLISH,PRIMARILY BECAUSE OF THE EFFECT OF THE LONGITUDINAL THERMAL ...

There are increasing demands to use high-beam-current, high-radio-frequency (RF) power, S-band cavities in existing and newly planned accelerator projects, in order to produce a very brilliant, broadband, coherent teraherz synchrotron radiation source (or for other purposes). For optimum performance, a critical technical challenge is to replace the present low-gap-voltage RF cavity with a very hi ...

The superconducting radio-frequency cavities being tested for use in the International Linear Collider are made from high purity niobium sheet metal, which has an inherent, performance-hindering "damaged layer." This surface layer is removed by acid treatments, which result in hydrogen contamination and necessitate high-temperature, vacuum heat treatments. This project will develop technology bo ...

The long-term monitoring of groundwater contamination plumes, needed to determine the fate of contaminants generated from past weapons-production activities, is expensive and labor intensive. Becauses of the high costs, monitoring programs collect less data than required to fully understand the fate and transport mechanisms of the contaminants. One source of the high costs is the expense associa ...
