Thick carbon foils (>300 mg/cm)has been used for stripping of H ion beam into protons at the injection stage of the 3GeV Rapid Cycling Synchrotron (3GeV-RCS) in J-PARC. The carbon stripper foils with high durability at high temperature >1800 oK are strongly required. A new irradiation system for foils is in progress using the KEK 650keV Cockcroft-Walton accelerator which can simulate the high-e...

An autostereoscopic display using a directional backlight with a fast-switching liquid-crystal (LC) display was designed and fabricated to obtain a better perception of 3D images by enhanced resolution and brightness. A grooved light guide in combination with an asymmetric focusing foil was utilized to redirect the emitting cones of light to the left and right eyes, respectively. By designing t...

The ratio of oxygen atoms to ions (O /O +) generated during electron stimulated desorption (ESD) from V20 s and oxidized V foil has been investigated. Desorbates were probed directly with high resolution quadrupole mass spectrometry. X-ray photoelectron spectroscopy was used as an indirect probe to measure the ESD induced surface oxygen loss. Despite the number of ESD target preparation methods...

-An absolute measurement of the 235U fission cross section has been carried out using a S4Na-Be photoneutron source with median neutron energy of 964 keV. A symmetric two-foil experiment was set up to measure the fission rate in a low-albedo laboratory, and variations in the sourceto-foil spacing used to determine the room background. Fission fragments passing through a limited solid angle aper...

From 1999 to 2006 the NASA Stardust mission collected cometary particles from the Wild 2 comet and interstellar dust from the interstellar medium in two collectors made from aerogel tiles and aluminum foil. By studying their isotopic compositions, these particles can provide us with information about nucleosynthetic processes in stars. Both collector trays are being studied for traces of these ...

The Los Alamos computational model of exploding metallic foil behavior has been used to analyze and design a wide range of experiments in which exploding metallic foils were driven by the output current of capacitor banks and magnetic flux compression generators. Currents in the experiments ranged from 1 kA-16 MA and foil conduction times ranged from 200 ns-300 J.lS. The successes and limitatio...

We present the system nFOIL. It tightly integrates the naı̈ve Bayes learning scheme with the inductive logic programming rule-learner FOIL. In contrast to previous combinations, which have employed naı̈ve Bayes only for post-processing the rule sets, nFOIL employs the naı̈ve Bayes criterion to directly guide its search. Experimental evidence shows that nFOIL performs better than both its base line...

Large solar panels were constructed from polymer solar cell modules prepared using full roll-to-roll (R2R) manufacture based on the previously published ProcessOne. The individual flexible polymer solar modules comprising multiple serially connected single cell stripes were joined electrically and laminated between a 4 mm tempered glass window and black Tetlar foil using two sheets of 0.5 mm th...

The Dye-sensitized nanocrystaline TiO2 solar cell (nc-DSC) developed by Grätzel [1] has the potential to reach low costs in future outdoor power applications. In addition, due to its expected ease of production and possibilities to adjust its appearance, the potential for application is very broad. When plastic foil is used as a substrate for the nc-DSC the production and application possibilit...

Herein, we demonstrate that an electrochemical surface treatment of Fe foil with simple pulse reverse electrodeposition (PRED) prior to thermal oxidation can substantially enhance the photoelectrochemical (PEC) stability and water splitting performance of Fe2O3/Fe photoanodes. Comprehensive structural (XRD, FESEM, and HRTEM), compositional (XPS depth profiling), and electrochemical (EIS and Mot...
