Cryogenic soft X-ray detectors are enabling new analytical capabilities for science, engineering, materials characterization, and time-resolved studies. X-ray microcalorimeter detectors are increasingly being used at synchrotron light sources, with scanning electron microscopes and other analytical instrumentation. These detectors must be protected from the environments in which they operate by so ...

Advances in soft X-ray detector technology have enabled higher count rates while maintaining high spectral resolution. These new superconducting detectors share the common form of a pixilated active area that must be operated in the milli-Kelvin temperature range below the boiling temperature of liquid helium. Because the cryogenic detectors are under high vacuum and must be able to sense ambien ...

The performance and productivity of DOE synchrotron systems is hindered due to focusing limitations from imperfections in the mirror surfaces. The ability to manufacture higher quality mirrors is directly limited by the accuracy and efficiency of the systems used to measure them. Currently available measurement methods do not provide the manufacturing feedback or quality control to allow efficien ...

Improvements in performance of the components are needed for polymer electrolyte membrane (PEM) electrolyzers, which is one of the key technologies for DOEs hydrogen production plan. In particular, high- performance ion-exchange membranes are needed that can withstand significantly higher mechanical loads due to high-pressure operation, while having significantly reduce hydrogen permeability and i ...

There is a clear requirement for gathering greater quantity and quality of atmospheric data in the Arctic regions. The harsh nature of the environment combined with remote location creates the need for technological solutions. Current efforts have successfully used small unmanned aerial systems (UAS); however, a large cost in both time and money is incurred when miniaturizing sensors to fit with ...

This proposal addresses the need for low-cost sensors to provide accurate, long-term in-situ monitoring of soil moisture content, and other physical and chemical soil properties of relevance to carbon cycling. Vista Clara proposes to develop very low-cost, highly accurate unattended NMR soil moisture measurement sensors for long term monitoring of soil moisture and other physical and chemical prop ...

The global GDP has gone up from $38 Trillion in 2000 to $60 Trillion in 2009. Price increase in consumer products is directly proportional to rate of growth of global GDP. Fatty acids form the basic building blocks of skincare as well as personal hygiene consumer products. Within the last decade, fatty acid prices have more than quadrupled. Fatty acids with carbon range of C8 to C12 are prod ...

High order mode (HOM) absorbers are very important to stable operation of accelerators. It has been very difficult, especially for superconductor radio frequency (SRF) accelerators, to find a suitable HOM absorber material that not only can function at cryogenic temperatures and vacuum compatible with extremely clean environment but with batch-to-batch repeatability of its electromagne ...

To address the DOE need for a high-power laser source used for synchronous photoinjection of GaAs photoemission guns, AdValue Photonics proposes to develop a radio-frequency (RF) synchronized 100W green fiber laser source with a repetition rate near 1GHz. Although GHz-rate mode-locked solid-state/fiber lasers in the near infrared have been previously demonstrated, which could be used as ...

Switching power amplifiers (SPAs) have a wide variety of applications within the fusion science community, including feedback and control systems for dynamic plasma stabilization in tokamaks, inductive and arc plasma sources, Radio Frequency (RF) helicity and flux injection, RF plasma heating and current drive schemes, ion beam generation, and RF pre-ionizer systems. SiC MOSFETs offer ...
