A radio-frequency (RF) photoreflectance technique, which senses changes in sample conductivity as carriers recombine following excitation by a laser pulse, has been used to measure the recombination parameters in 0.55 eV InGaAsSb lattice matched to GaSb. Doubly-capped lifetime structures with variable active layer thicknesses are used to extract the surface recombination velocity (SRV), while analysis of the samples with different doping concentrations is used to obtain Auger (C) and radiative (B) recombination parameters. Parameter extraction for the samples evaluated gives C = 1 {+-} 0.4 x 10{sup -28} cm{sup 6}/s and B = 3 {+-} 1.5 x 10{sup -11} cm{sup 3}/s for 0.55 eV InGaAsSb lattice matched to GaSb. The Auger and radiative recombination coefficients obtained from high-level injection decay times in low doping concentration samples show very good agreement with values obtained from low-level injection conditions.

In the following text we analyze and compare results of the two publications ([1], [2]), dedicated to development of the tunable high-gain Free Electron laser (FEL), seeded by an external source. As a conclusion we summarize similarities and differences between these concepts. This note is initiated by the polemics on the similarity of two different schemes of the wavelength tuning in a seeded high-gain FEL. Below we will be calling the scheme, presented by S. Biedron, S, Milton and H. Freund in Nuclear Instruments and Methods of 2001 ([1]), as the first (1st) scheme. The scheme that we developed and presented in the BNL preprint ([2]) will be called as the second (2nd) scheme. The following analysis provides important information on similarities and differences between both techniques. We start by considering the first approach. As we understand, the goal of the Modular Approach is to make X-ray FEL design more flexible [1]. Usual linac-based FELs begin from a long linac with bunch compressor(s) followed by an FEL magnetic system. The essence of the Modular Approach is to break a machine into modules and then recombine these modules in a more efficient way (from the point of view of monetary and/or …

The Salt Waste Processing Facility and the Actinide Removal Process at the Savannah River Site will remove alpha emitting radioisotopes from High Level Waste to meet regulatory disposal requirements. The removal occurs prior to removal of the radioactive cesium. Both facility designs currently include verification measurement using conventional wet chemistry approaches remote from the operation. Use of an on-line monitor for this purpose offers the opportunity to shorten process cycle time and thereby increase facility throughput. Personnel from Pacific Northwest National Laboratory designed, built, and functionally tested an on-line monitor, which is capable of measuring the residual transuranic concentrations in processed high-level wastes with a detection limit of 370 Bq/mL (10 nCi/mL) in less than six hours. Personnel from Savannah River National Laboratory assisted in the design and tested the equipment using actual waste. The monitor measures the neutrons produced by the transuranics in the presence of gamma-ray fields up to 1 Sv/h (100 R/h). The optimum design derives in part from Monte Carlo modeling tempered with practical engineering and cost considerations. We demonstrated operation of the monitor in a cell utilizing an actual sample of high-level waste. Results of that demonstration are given, and suggestions for improvements in the …

This program was successful in achieving its primary objectives. Namely, succeeded in the development of multiple synthetic routes to a wide variety of new candidate CVD precursor compounds.

Energy conversion efficiencies of better than 23% have been demonstrated for small scale tests of a few thermophotovoltaic (TPV) cells using front surface, tandem filters [1,2]. The engineering challenge is to build this level of efficiency into arrays of cells that provide useful levels of energy. Variations in cell and filter performance will degrade TPV array performance. Repeated fabrication runs of several filters each provide an initial quantification of the fabrication variation for front surface, tandem filters for TPV spectral control. For three performance statistics, within-run variation was measured to be 0.7-1.4 percent, and run-to-run variation was measured to be 0.5-3.2 percent. Fabrication runs using a mask have been shown to reduce variation across interference filters from as high 8-10 percent to less than 1.5 percent. Finally, several system design and assembly approaches are described to further reduce variation.

Correspondence issued by the Government Accountability Office with an abstract that begins "The Securities and Exchange Commission's (SEC) primary mission is to protect investors and the integrity of securities markets. Among other things, SEC regulations require companies to file reports with SEC disclosing information that would be considered "material" to a reasonable investor. A matter is material if there is a substantial likelihood that a reasonable person would consider it important. Environmental risks and liabilities are among the conditions that, if undisclosed, could impair the public's ability to make sound investment decisions. For example, the discovery of extensive hazardous waste contamination at company-owned facilities could expose a company to hundreds of millions of dollars in cleanup costs, while impending environmental regulations could affect a company's future financial position if the company were required to shut down plants or invest in expensive new technology. To monitor companies' disclosures, SEC reviews their filings and issues comment letters requesting revisions or additional information, if needed. Although the Environmental Protection Agency (EPA) does not have a direct role in monitoring environmental disclosures, the agency notifies companies of potential disclosure obligations and periodically shares relevant information with SEC. The report addresses (1) key stakeholders' views …

Instabilities driven by ions (or electrons) trapped within the space charge potential of a circulating beam are common in accelerators and storage rings. In the recycler, the stored antiproton ({bar p}) beam could trap positive ions (H{sub 2}{sup +}, CO{sup +}, etc.). Conditions for trapping are discussed, and trapping potentials are calculated. Ion trapping can be reduced by clearing electrodes, a beam-free gap (or gaps), and beam shaking. Tune shifts, coherent instabilities and other effects of trapped ions on stored {bar p}'s are discussed. A ''fast-ion'' instability mode is also possible. Experiments to determine conditions and consequences of such instability in the recycler are discussed.

This paper presents a case study of the residential heat pump water heater (HPWH) market. Its principal purpose is to evaluate the extent to which the HPWH will penetrate the residential market sector, given current market trends, producer and consumer attributes, and technical parameters. The report's secondary purpose is to gather background information leading to a generic framework for conducting market analyses of technologies. This framework can be used to compare readiness and to factor attributes of market demand back into product design. This study is a rapid prototype analysis rather than a detailed case analysis. For this reason, primary data collection was limited and reliance on secondary sources was extensive. Despite having met its technical goals and having been on the market for twenty years, the HPWH has had virtually no impact on contributing to the nation's water heating. In some cases, HPWH reliability and quality control are well below market expectations, and early units developed a reputation for unreliability, especially when measured against conventional water heaters. In addition to reliability problems, first costs of HPWH units can be three to five times higher than conventional units. Without a solid, well-managed business plan, most consumers will not be drawn …

A new nuclear magnetic resonance (NMR) method is presented which produces linear, isotropic proton-detected local-field spectra for InS spin systems in powdered samples. The method, HETeronuclear Isotropic Evolution (HETIE), refocuses the anisotropic portion of the heteronuclear dipolar coupling frequencies by evolving the system under a series of specially designed Hamiltonians and evolution pathways. The theory behind HETIE is represented along with experimental studies conducted on a powdered sample of ferrocene, demonstrating the methodology outlined in this paper. Applications of HETIE for structural determination in solid-state NMR are discussed.
