Neutron scattering experiments provide unparalleled contributions to physical, chemical, and materials science. At present, the US Government through DOE-BES operates two premier neutron scattering centers These facilities serve a broad and growing user community whose expanding needs require improved operational efficiency and capacity at those facilities. The automation of sample alignment proce ...

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 ...

Over the past two decades, there has been a drastic advance in the sensing technologies and data acquisition systems. These technologies have been deployed in carbon sequestration to continuously monitor CO2 migration and location during and after injection. A complex network of surface and underground sensors is often installed generating large volume of intricate datasets. These datasets require ...

Emerging hardware architectures offer attractive performance opportunities for those software applications that are able to exploit them. However, many scientific codes written over the last decade require an intensive porting effort in order to take advantage of new hardware architectures. Component-based software architectures can ameliorate this effort by making it possible to develop interop ...

THE CONTAMINATION OF GROUNDWATER BY HEAVY METALS, RADIONUCLIDES, AND ORGANICS IS A SERIOUS ENVIRONMENTAL PROBLEM. IN SOME CASES IT MAY NOT BE POSSIBLE TO REMOVE ALL OF THE MATERIAL FROM THE SOIL BY CONVENTIONAL PUMP-AND-TREAT TECHNIQUES. IN SUCH CASES, THE RESIDUAL MATERIAL MUST BE CONTAINED TO PREVENT FURTHER MIGRATION. AN IDEAL SOLUTION WOULD BE A PERMEABLE BARRIER THAT IS READILY INSTALLED A ...

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 ...

A CATALYTIC COMBUSTION FLOW CALORIMETER FOR THE MEASUREMENT OF NATURAL GAS ENERGY CONTENT WILL BE DEVELOPED AND TESTED. THIS NEW CALORIMETER (GAS ENERGY METER) WILL BE DESIGNED TO BE A PROTOTYPE FOR DEVELOPMENT OF AN INSTRUMENT SUITABLE FOR REMOTE INSTALLATION, AS ACCURATE AS PRESENT LABORATORY CALORIMETERS, OPERABLE CONTINUOUSLY FOR PRECISE ACCOUNTING AT CUSTODY TRANSFER POINTS, AND LOW IN COST. ...

To achieve higher efficiencies, lower emission, improved reliability and availability, and stable control and operation through feed-forward control systems, fossil energy power generation facilities (e.g. emerging modular power systems) needs fuel gas composition data to identify any post-production cleanup options and allow fine-tuned control of the combustion process. Ideally, such a monitoring ...

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 ...
