A high-brightness, elliptic, electron or positron beam is a novel device that has wide applications in high energy accelerators. Once developed, a large-aspectratio elliptic electron beam would enable the development of L-band ribbon-beam klystrons (RBKs) or sheet-beam klystrons (SBKs), which are more efficient than the multi-beam klystrons (MBKs) for the International Linear Collider (ILC). Als ...

High efficiency radio frequency (RF) power sources are needed in the frequency range 300-1500 MHz because they are essential for the operation of high-power particle accelerators for nuclear physics research. Applications include the Continuous Electron Beam Accelerator Facility (CEBAF) at Thomas Jefferson National Accelerator Laboratory (JLab), the Relativistic Heavy Ion Collider (RHIC) and Elec ...

With people spending more time indoors, concerns about the impact of indoor environmental quality ¿ on human health, comfort, productivity, energy efficiency, building security, and respiratory disease control ¿ are rapidly increasing. Low-cost, reliable, and easy-deployment sensor systems are needed to monitor and control building environmental parameters. This project will develop an integra ...

Oil shale deposits are vast throughout the western parts of the United States and Canada. It is estimated that 500-1,000 billion recoverable barrels of oil are present in the US alone. The quantity of oil held in these reserves could provide enough energy to allow the U.S. and Canada to significantly reduce their dependence on foreign oil. However, the lack of an economical and environmentally ...

The current and future rapid growth of the fuel ethanol industry presents many opportunities for the development and integration of cost-saving and energy-saving innovations. Much of the energy consumption in industrial ethanol production is related to the processes used to extract and concentrate the ethanol from aqueous fermentation media. Technology improvements in ethanol extraction could si ...

Charged particle accelerators are key tools in the study of the fundamental properties of matter and energy. Although accelerators can cost billions of dollars, they are only as effective as the detectors in them. Man-made diamond has exhibited potential as a relatively new detector material. Its unusual radiation hardness and high charge carrier mobility make it superior to existing silicon so ...

New, ultrafast, ultra-intense solid state lasers can be efficient sources of accelerated particle beams in applications ranging from high energy physics research to real world medical applications. However, parasitic lasing represents a severe bottleneck to scaling-up this new technology. Removing this bottleneck would efficiently bring accelerator technology to a wide range of real world proble ...

The very demanding requirements of the International Linear Collider (ILC) will require the development of solid-state kicker drivers. The ILC will use ¿damping rings,¿ and the cost of each damping ring will depend strongly on the speed of these kickers. This project will investigate two approaches to the development of the solid state kicker driver: the first will utilize commercially availa ...

The International Linear Collider (ILC) will be the largest and most expensive accelerator built to date. Its radio frequency (RF) subsystems ¿ which encompass all of the equipment from external grid power to the delivery of RF power to each of the 20,000 accelerating cavities ¿ are currently estimated to cost ~$1.2B, one of the largest cost items in the ILC design. The baseline ILC approach r ...

CZT (Cd0.9Zn0.1Te) gamma radiation detectors are presently the best candidates for room temperature operation, in order to identify radiological isotopes in materials for military, medical, and commercial applications. Presently, the typical energy resolution of CZT detectors is on the order of 2%, rather than the desired =5%. To achieve this energy resolution goal, this project will employ nove ...
