Most radio-frequency (RF) particle accelerators worldwide rely on normal conducting RF cavities to accelerate the particle beam. A few large research accelerators such as the Continuous Electron Beam Accelerator Facility (CEBAF) at Thomas Jefferson National Laboratory (JLAB) use superconducting radio frequency (SRF) accelerating cavities. SRF cavities consume less power than normal cavities to p ...

Protecting Organic Light Emitting Diodes (OLEDs) from moisture and oxygen remains the key technical challenge for fabricating flexible, solid-state lighting displays with acceptable service lifetimes. Although OLED-based displays on flexible PET polymer substrates have been demonstrated, they exhibit poor operating lifetimes due to atmospheric exposure. This project will develop a high-throughpu ...

Radio frequency (RF) cavities, key components in particle accelerators for fundamental high energy physics research, increasingly utilize superconducting technology to achieve higher accelerating field gradients. Traditionally, superconducting RF cavities are made of niobium, which, although expensive and difficult to fabricate, is able to be formed into large mechanical structures. Recently, in ...

ACTA Incorporated (ACTA) and Sandia National Laboratory (SNL) propose a six-month STTR Phase I feasibility Project titled "Expedited Transition of Propulsion Modeling & Simulation Capability." The stated objective of this solicitation topic is to expedite industry transition of a validated safety and IM (Insensitive Munitions) related modeling & simulation (M&S) capability for propulsion design a ...

ACTA Inc. and Los Alamos National Laboratory propose to develop a high fidelity physics based modeling and simulation toolset for use in evaluating the hazards and consequences associated with hypergol fuel accidents for use in missile defense applications. Los Alamos' CartaBlanca multi-physics code will be evaluated to determine its ability to model both small leaks (resulting in ppm toxic relea ...

The exploration and production of oil and natural gas is one of the most computationally demanding endeavors, generating terabytes of data. To optimize the management of a producing oil field or to find new reserves, the E and P data must be readily available to a multidisciplinary asset management team. The data must be easy to access, and it must be effectively managed by a team of geologists, ...

Electrochemical capacitors are being developed for utility applications, providing emergency backup power, improving system stability, and lowering demand peaks. These functions reduce congestion at critical times for transmission and distribution systems. However, the use of electrochemical capacitors is limited by their performance (energy and power densities), safety, and short cycle life. T ...

In previous research, a specialty solid-state lighting (SSL) device had been developed. A doped Polymer Light-Emitting Diode (POLED) device structure is used, which enables devices to be printed with low capital equipment and operating costs. Although the devices are efficient, thin, flexible, and robust, additional performance improvements would broaden the range of applications to interior bui ...

The accurate detection of neutrons can make invaluable contributions to the physical, chemical, and biological sciences, and the DoE operates neutron user facilities to support these endeavors. This project will build a compound refractive prism (CRP) that refracts and spatially separates neutrons according to their wavelength, providing greater spatial separation of neutron wavelengths than a si ...

There are no long-lived gamma-ray calibration sources with energies above 3.5 MeV, which is an impediment to the calibration of high-purity-germanium (HPGe) and scintillation detectors used in cutting edge experiments in nuclear physics, astrophysics, and homeland security. In addition, there are growing safety and security concerns about the storage of radioactive sources currently in use. The ...
