The proposed Ph-II research project will be led by Alameda Applied Sciences Corporation, in collaboration with Jefferson National Accelerator Facility (JLab) and Norfolk State University (NSU) via subcontracts. This team covers the gamut of fundamental research into new Superconducting Radio Frequency (SRF) materials: (i) to first characterize the materials properties such as morphology, grain siz ...

There are numerous fields in which fast pulses of supersonic gas jets are useful. One such application is for the laser wakefield acceleration of electrons. Currently, valves with opening times on the order of hundreds of microseconds and closing times that are even longer are used to supply the gas or small capillaries that are used to control the gas density. This project will develop techno ...

Traditional cyber-security methods are inadequate to address the increasing number of threats within larger and higher-performance networks. The U.S. Computer Emergency Readiness Team (US-CERT), the National Institute of Standards and Technology (NIST), the Department of Energy (DOE) Office of the Chief Information Officer (CIO), and many other organizations report consistent failures within thes ...

High performance network users are frequently unable to achieve adequate throughput when transferring large files across wide-area networks. In general, such poor file transfer performance over ¿long fat networks¿ (LFN) is primarily caused by limitations in transport protocols and network stack configurations on end-system hosts. In addition, some traditional file transfer applications have in ...

There is a need for improved collaboration between and within groups of network operators and users. At present, a variety of tools exist to share network health and status between domains, reserve resources across multiple networks, and remotely access computing and storage resources. However, no unified environment exists that combines these tools into a single, easy-to-use framework. Further ...

In order to enable the efficient use of high performance networks, the DOE has invested substantial resources in the development of next-generation network provisioning systems. For example, the DOE-funded tool, On-demand Secure Circuits and Advanced Reservation System (OSCARS), enables users to dynamically provision network paths with Quality of Service (QoS) guarantees. Additional work is requ ...

An estimated 70% of supercomputing cycles worldwide are spent solving large-scale systems of linear equations. Sparse linear equations are at the core ¿ and constitute the primary bottleneck ¿ of important DOE research problems in energy fusion, accelerator simulations, and astrophysics, among other research challenges. The DOE has co-funded an ambitious research program to develop the LAPACKr ...

An estimated 70% of supercomputing cycles worldwide are dedicated to solving numerical linear algebra problems, and large-scale ¿least-squares¿ computational problems are an important subset of numerical linear algebra. Sca/LAPACKrc, a multimillion dollar program to develop FPGA-accelerated linear algebra software, already has demonstrated speedups larger than 100x per commodity processor for a ...

A promising approach to the clean use of abundant U.S. coal resources is the production of hydrogen through coal gasification. The synthesis gas resulting from coal gasification is required to undergo several processes in order to produce hydrogen of sufficient purity for fuel cells or hydrogen-fueled turbines. Therefore, systems that combine purification and separation of syngas to produce high ...

Governments and industry have recently placed significant emphasis on finding affordable renewable fuels to supplement and/or replace fossil fuel use. Biodiesel produced from microalgae has been identified as a highly attractive option for affordable renewable fuel. This project will develop a low cost, high-efficiency algal biomass harvest and dewatering process. In Phase I, a small scale syst ...
