Structural failure can be predicted by sensing ultrasonic acoustic emissions, spontaneously created when stress energy is released as metals fatigue due to a cyclic load. However, conventional piezoelectric sensors suffer rapid performance degradation when exposed to extreme temperatures and neutron radiation, limiting their ability to monitor the health of nuclear infrastructure. We will develop ...

Modern particle accelerator facilities generate large amounts of data and face increasing demands on their operational performance. These datasets can be difficult to visualize and contain complex relationships that are challenging to understand. Additionally, as the demand on accelerator operations increases so does the need for automated tuning algorithms and control to maximize uptime with redu ...

The Advanced Photon Source (APS) at Argonne National Laboratory (ANL) is a third-generation, high-brightness, 7 GeV storage-ring-based x-ray light sources that has been in operation since 1996. Several possible long-term upgrades to the APS are investigated at Argonne, including an ERL-based upgrade and an Ultimate Storage Ring (USR), both of which could provide more than two orders of magnitude i ...

Although means currently exist to capture CO2 from combustion and other sources, capture at atmospheric levels is difficult. Once captured, CO2needs to be released in concentrated form and sequestered: e.g., it can be buried under ocean water or in underground vaults, or it can be reacted with basic metal oxides to form metal carbonates. CO2 may also be reduced, via the Sabatier reaction, to metha ...

Over the past few years several beam halo detection techniques have been invented to minimize the beam interception rate and accuracy of measurements. However, instrumentation for these measurements are complex systems and are not modular. The systems tend to be specialized for a single facility, or even a single part of a beamline. Also, these systems can hardly be reused or moved to another loca ...

ITN Energy Systems (ITN), along with Texas A & amp;M University, proposes to demonstrate a proof-of- concept feasibility of a low cost, oxygen separation (enrichment) system that works on the interception effect of a gradient magnetic field in the presence of magnetic polymer beads. At present much of the oxygen enrichment market is based primarily on cryogenic systems, ion transport membranes mad ...

Statement of the problem: If high‐quality phase shifters can be made rapidly and inexpensively, it will enable substantial improvements in free electron lasers (FELs) performance and benefit the exploration of atomic and molecular science. X‐ray FELs now use permanent magnetic undulators to produce x‐ray light by wiggling high‐ energy bunches of electrons in alternating magnetic fields, wi ...

When considering high-performance parallel computers, it is easy to overlook the importance of disk storage. In this proposal, we seek to address the topic of disk storage for parallel computers, and create a deployable, robust file system that will reduce downtime due to faults and increase productivity through improved system performance. For this project, Galois will take a synthesis approach, ...

The use of virtual design in the fabrication of large structures has enjoyed significant success in the heavy materials industry for almost two decades. Industries that have used virtual design and analysis tools have reduced material parts size, developed environmentally-friendly fabrication processes, improved product quality and performance, and reduced manufacturing costs. The proposed projec ...
