The nuclear physics data acquisition systems are challenged by the increasing demand for flexibility, accuracy, volume of data and processing speed, massive scalability, upgradability, and lower acquisition operations and maintenance costs. General precision timing synchronization for all Detector and DAQ components provides novel and original solutions to these problems especially if it can be ac ...

Almost 15 million metric tons per year of essentially pure CO2 is captured in the United States from ethanol, hydrogen, ammonia, and natural gas processing plants. Some of this CO2 is used for merchant applications such as food and beverage and other applications, but a large portion of this captured CO2 is emitted to the atmosphere. This CO2 can be converted into high value chemicals, but the key ...

The simulations on which we depend must adapt to changing hardware to run at exascale. The Asynchronous Many Task (AMT) model is a viable alternative to existing techniques and has numerous advantages. In situ data visualization and analysis remains an important fixture of computing for exascale so these algorithms must be expressed in terms of AMT so they will be compatible with emerging computin ...

Determination of soil gas concentrations and isotopologue ratios are a critical tool in plant, microbial and ecosystem ecology, hydrology, biogeochemistry studies, and interrogation of environmental remediation. In addition, the most abundant elements utilized and exchanged by plants, microbes and ecosystems are carbon (C), hydrogen (H), oxygen (O) and nitrogen (N), all of which respond to redox c ...

Aromatics are the main building blocks for petrochemical products and intermediates. With the majority of US crackers switching to natural gas liquids, aromatics supply from crackers has fallen in recent years. In 2017, US imported more than 1.8 million tons of benzene mainly due to the shift to a very light feedstock (mainly ethane) in steam crackers. As a result, the aromatics industry will be i ...

Detecting and characterizing facilities and performing emergency location requires multi-modal, persistent surveillance by sensing and analysis. Infrasound and radio frequency direction finding (RF-DF) sensors have the proven ability to provide standoff detection. The project will demonstrate the feasibility of a small sensor package designed for small and medium unmanned aerial vehicles (UAVs) wi ...

The proposed effort is a critical part of MVA programs for CO2 sequestration. The benefits include improved zonal isolation, higher data rates, and longer sensor battery life. Understanding reservoir stability and annulus cementing integrity will help determine new isolation criteria and verify existing operation. The new sequestration wells have applicability for greenhouse gas storage, environme ...

Separations often account for a majority of process costs. This is because all traditional separation processes have inherent weaknesses that prevent the system from achieving perfect (or even near perfect in many instances) selectivity. These weaknesses result in large recycle streams and require multiple separation units in concert in order to produce a product clean enough for use or sale. An a ...

Under recent economic pressures, the nuclear power industry has explored options to reduce costs and increase electricity generation. One overlooked area where lost power output can be recaptured and attendant problems (e.g., flow-induced vibration) addressed is the main steam piping system. The technology underlying this system is essentially over a 100 years old, and incentives to improve pipe c ...

A rugged reliable cathode technology for application in superconducting radio frequency industrial linear accelerators will be developed. The non-thermionic cathode has no low work function surfaces and as a result is not sensitive to background gases or pressure. The high current cathode operates in pulsed mode over a wide frequency range. The simple construction of the cathode makes it easy to r ...
