In an x-ray free-electron lasers (XFEL), a high quality relativistic electron beam from a linear accelerator traverses an array of undulator magnets to generate a high power x-ray beam by allowing the FEL to reach saturation. In many XFELs, phase shifters haven’t been commonly used or included in their designs. The importance of the phase shifter was recognized only recently. A phase shifter can ...

ATC requests Phase 1 SBIR funding to develop a 2-layer NbTi Cable-in-Conduit (CIC) conductor suitable for a large-aperture 6 T dipole. ATC has successfully developed a single-layer 13 kA NbTi CIC cable, and our collaborators at Texas A&M University (TAMU) have successfully used it to make a 3 T dipole suitable for the arcs of a 100 GeV Ion Ring that has until now been the baseline design for JLEIC ...

Thermoelectric coolers (TECs) are solid-state devices with no moving parts and working fluids to provide reliable cooling power compared to traditional cooling systems such as vacuum compressors. However, their relatively high cost, small form factor and low efficiency have relegated them to niche applications such as small scaled portable coolers and yet to justify the large volume cooling compet ...

Imaging of molecular components of plant tissue (roots, leaves, seeds etc.) by microfocused laser desorption is maturing into a useful tool for describing plant molecular biology. Due to pioneering work in DOE laboratories and elsewhere the detection sensitivity of laser desorbed molecules is increased by the addition microscale sized colloidal metals (e.g. Sliver) or graphite to aid as a “matri ...

Cryo-electron microscopy is a powerful imagining technique that can generate highly accurate structural models for macromolecules larger than 200 kDa. However, for macromolecules having smaller masses, the amount of information used to generate structural models is frequently insufficient to result in successful structure determination. The barrier defined by macromolecular mass arises from cryo-E ...

Data influx from sources at the edge of the network is exploding e.g. from sensors to collect weather data, satellite imagery, seismic sensors, LIDAR data for autonomous vehicles. Whereas traditionally over the last decade compute and storage has become increasingly centralized in the cloud. This dichotomy prevents low-­‐latency decisions and actions triggered by the data as well as incurs high ...

Supercritical CO2 (sCO2) power cycles operate at high pressures (300 bar) and high inlet temperatures (700°C), placing the CO2 well above the critical point. Current plans are to operate these devices using natural gas or syngas, burning with oxygen at fairly low combustion temperatures (1100 °C). However, there are gaps in the understanding of oxy-fuel combustion with CO2 under supercritical co ...

Accurate determination of state of stress at a field site is key in order to evaluate the geomechanical impacts of any industrial operation that involves injection of fluids into the deep subsurface. Direct borehole measurements of the orientation of the stress field are typically expensive, spatially limited, restricted to shallow depths, and potentially compromised by the drilling itself. Though ...

Dry methane reforming consumes two greenhouse gases (carbon dioxide and methane) and coverts them to syngas that can be used to produce liquid fuels and other chemicals. Using catalysts, this reaction occurs at temperatures of 600-900oC, yet conversion has been limited and carbon-forming reactions that deactivate catalysts are often a problem. In this Phase I study, we propose an innovative approa ...

Today, the US Land Unconventional Resource market increasingly deploys advanced geosteering methods with the primary objective of maximizing length of wellbore lateral section in target zone to optimize production. Real time geosteering work flows are best driven by relatively expensive near-bit measurements but instead are generally supported with less effective, low cost MWD solutions that are i ...
