Advanced, high brightness photoinjectors are required for the next generation of linear accelerators and free electron lasers. Current photoinjector lasers suffer from complexities related to the use of multiple amplifier stages to achieve the desired pulse energy. There are also issues related to power scaling. This project will investigate the use of a liquid nitrogen cooled, Yb:YAG, mode-loc ...

A solution is needed for the inexpensive generation of electricity from solar irradiation, which will be cost competitive with fossil fuel technologies without the need for government subsidies. This project will fabricate and characterize inorganic nanoparticle-based solar cells that: (1) can be manufactured with low cost processing techniques; and (2) will offer greater absorption across the s ...

Bi2212, which has the highest Jc of any practical superconductor at fields greater than 15 T, is currently being considered for high-field particle accelerator magnets. In particular, it is attractive for high field magnets that are needed to improve the performance of machines such as the Large Hadron Collider and Muon Collider. However, the processing requirements for Bi2212 are extremely stri ...

This project will develop inexpensive and environmentally benign LiMnPO4 cathodes for applications to lithium-ion batteries (LIB) used in electric and hybrid electric vehicles. This cathode material is expected to be far safer than Li-ion batteries employing traditional layered LiMO2 (M=Co, Ni) materials. A number of synthetic modifications will be pursued to optimize the LiMnPO4 material for us ...

Lithium-ion batteries are promising energy storage devices for hybrid and electric vehicles, providing high specific energy (approximately 150 Wh/kg), energy density (approximately 400 Wh/L), and long cycle life (greater than 15 years). However, these applications require further increases in energy density and improved low-temperature (less than ¿10 degrees C) performance. Silicon-based anod ...

Distributed, collaborative visualization and control of real-time fusion experiments and simulations is of growing importance, because the next major facilities will be internationally located and operated. Currently, collaborative visualization tools for tiled displays in control rooms have substantial overhead and are not satisfactory for tracking dynamic displays. This project will build on m ...

A growing number of electronic devices are being implanted in patients to treat a wide range of maladies. While these devices are becoming increasingly sophisticated and complex, they are powered by conventional chemical batteries with limited operating life and power output. These conventional batteries are essentially self-contained electrochemical reactors, and the total power they can produc ...

The design of complex three-dimensional (3D) charged particle devices, used in high energy physics research, is extremely difficult. It has been recognized that computer optimization can provide a critical tool for designing the next generation of advanced, higher performance devices. Therefore, this project will implement computer-optimized design technology in advanced 3D simulation tools for ...
