The composition of atmospheric particulate matter (“aerosols”) strongly influences health and environmental impacts, but there exist few time-resolved, long-term records of particle-phase chemical composition due to lack of appropriate monitoring tools. Needed is an instrument that is robust, easy-to-operate, with automated calibrations and data reduction, to provide operationally-inexpensive ...

Redox flow batteries are a promising technology for electrical energy storage for renewable energy sources; however traditional redox flow batteries are limited in their use due to non-uniform pressure drops and mass transfer limitations, as well as high manufacturing costs related to the felt material costs for the electrode and component alignment challenges during manufacturing.General Statemen ...

Considerable progress has been made in developing promising subsystems for muon beam cooling channels to provide the great reduction of emittances required for an Energy-Frontier Muon Collider; but an end-to-end design is lacking. Meanwhile, the recent discovery of a Higgs-like boson has created interest in the high-energy physics community for a Higgs Factory to investigate whether its propertie ...

Accurate simulation of nuclear power plant behavior is necessary for both engineering and training applications. An engineering grade simulator, used for design, safety analysis and operations, is characterized by high fidelity, computational power, lack of real-time capability, and user non-interactive environment. By contrast, a training grade simulator, used for operator training and education, ...

Nuclear fusion has great potential for supplying global energy needs with a clean, abundant energy source. Advanced superconducting magnets will be used to contain the plasma at the center of the reactor. To operate these magnets, new sensors are needed to monitor the superconductors in real-time to detect the signs that the superconductor may quench (lose superconducting properties), so that corr ...

The feasibility for fusion as a practical energy source needs to be enhanced significantly by removing some of the restrictions that low-temperature superconductors put on the fusion magnet systems. This can be done by using high-temperature superconductors, allowing for much larger temperature margins, a higher magnet performance and less mechanical degradation during operation. There are curren ...

The laser plasma accelerator (LPA) is a very promising technology for generating gamma rays for the detection of contraband bulk nuclear materials, but is currently limited by the rate at which the beam can be pulsed. Erosion of the capillary plasma channel is the main limiting factor and can be mitigated through the use of artificial diamond to construct the channel. Computational modeling and ...

Successful adoption of open frameworks such as perfSONAR in Science DMZs within DOE labs, universities, and small-businesses, and the emerging trends of software-defined cloud platforms that inherently require multi-domain performance transparency are major drivers for a new market. However, perfSONAR framework and other proprietary solutions developed by industry cannot be effectively integrated ...

Asymmetric ultracapacitors achieve greater energy density versus today

Bright coherent light sources in the soft x-ray region of the spectrum are useful for a variety of applications of interest to DOE in the basic sciences, nanoscience and biology, and for technological applications. At Free-Electron Laser Facilities, peak power output of the x-ray pulses is enhanced by using a mid-infrared laser pulse instead of a near-infrared pulse. The current front end for mid- ...
