75521S Radio frequency (RF) cavities are a key component in particle accelerators for fundamental high-energy physics research and medical applications. To enhance their capabilities, niobium-coated superconducting copper cavities have shown promise for supporting higher electric field gradients when compared to non-superconducting designs. However, a satisfactory coating method has not been de ...

Structural Health Monitoring (SHM) is increasingly being evaluated by the industry as a possible method to improve the safety and reliability of structures and thereby reduce operational cost. However, the scalability and applicability of SHM systems for the monitoring of large structures is still a challenge. The goal of the proposed effort is to develop the capability for enhanced in-situ struct ...

75903-Neutron radiography, which uses nuclear reactors and accelerators as sources of neutrons, has been demonstrated to be an excellent method for imaging high-density, thick objects for the detection of corrosion, voids, and cracks, particular in nuclear power plants. Unfortunately, no high brightness neutron sources exist that are portable, inexpensive and capable of neutron radiography in sho ...

76023-Among the contributors to atmospheric pollution, carboxylic acids (including mono- and dicarboxylic acids, aliphatic ketoacids, and aromatic acids) are an important class of oxygenated, organic compounds in atmospheric aerosols. To better understand their sources and atmospheric transformation processes, an automated method for measuring their concentration is required. This project will d ...

The current situation in Iraq is making it extremely clear that the urban environment is a chaotic and dangerous battle space. Currently available technology cannot provide the level of real-time situational awareness needed by each individual soldier. DARPA has determined that Sparse Conformal Acoustic Network (SCAN) technology, or soldier-worn acoustic-array “vests,” is a potential solution ...

76223S In order to facilitate energy independence, increased usage of alternative enery sources will be required. Unfortunately, of the renewable technologies now available, there are no viable alternatives that can produce power 24 hours a day. For example, wind energy requires a threshold wind speed and solar energy requires sunlight. However, if solar energy could be used to produce hydroge ...

STIL-NAVS will use STIL (streak-tube imaging lidar) technology to produce accurate ocean wave field maps. In Phase II, Areté Associates will adapt an existing Areté breadboard sensor. STIL-NAVS is planned to image waves sampled at 36Hz and at a lateral distance of 50m to 150m from a mast height of 10m with a 532nm laser diverged over a field-of-view of 7 deg. In the first year base period, STIL- ...

75527S The sheet-beam klystron holds great promise for providing high RF power for modern linear colliders. However, sheet beam generation is not readily amenable to computer simulation; therefore, experimental validation of the design is sorely needed. This project will develop a demountable sheet beam analyzer with a fluorescent screen for direct observation of the electron beam cross section ...

76075S The current classes of anode and cathode materials used for Li-ion batteries do not have sufficient energy density to meet many advanced application requirements. Intermetallic anodes have the potential to triple or quadruple the energy density over current carbon anodes, but have not been able to achieve the cycle life required in an economically viable manner. This project will develop ...

75546S Many Radioactive Ion Beam (RIB) laboratories around the world are using or planning to use Electron Cyclotron Resonance (ECR) Charge Breeders because they provide an economical way of producing RIBs. Currently, charge breeders, which produce multi-charged radioactive ions for nuclear physics research, produce the RIBs by a trial and error method. This project will investigate the beam ca ...
