Three high voltage modulators used during testing and operation of the Tevatron Electron Lens (TEL) at Fermilab will be described. Short high voltage (0 to {approximately} 20kV) pulses from these modulators vary the anode-cathode voltage of the TEL electron gun to control the magnitude of the electron beam current. The trio of modulators include a low repetition rate MOSFET-based pulser, a fast ionization device, and a high average power tetrode modulator. The characteristics of each device will be discussed and typical outputs from each type of modulator is shown.

In this study, we measured and documented summertime air-conditioning (a/c) daily energy savings and demand reduction from a reflective roof membrane retrofit on a large retail store in Austin, Texas. The original black rubber membrane was replaced with white thermoplastic resulting in a decrease in the average maximum roof surface temperature from 168 degrees F (76 degrees C) to 126 degrees F (52 degrees C). This building, with 100,000ft2 (9300m2) of roof area, yielded 3.6Wh/ft2 (39Wh/m2) in a/c average daily energy savings and 0.35W/ft2 (3.8W/m2) in average reduced demand. Total a/c annual abated energy and demand expenditures were estimated to be $7200 or $0.072/ft2 ($0.77/m2). Based on cost data provided by the building manager, the payback is instantaneous with negligible incremental combined labor and material costs. The estimated present value of future abated expenditures ranged from $62,000 to $71,000 over the baseline 13-year service life of the roof membrane.

Inorganic membrane reactors offer the possibility of combining reaction and separation in a single operation at high temperatures to overcome the equilibrium limitations experienced in conventional reactor configurations. Such attractive features can be advantageously utilized in a number of potential commercial opportunities, which include dehydrogenation, hydrogenation, oxidative dehydrogenation, oxidation and catalytic decomposition reactions. However, to be cost effective, significant technological advances and improvements will be required to solve several key issues which include: (a) permselective thin solid film, (b) thermal, chemical and mechanical stability of the film at high temperatures, and (c) reactor engineering and module development in relation to the development of effective seals at high temperature and high pressure. In this project, we are working on the development and application of palladium and palladium-silver alloy thin-film composite membranes in membrane reactor-separator configuration for simultaneous production and separation of hydrogen and carbon dioxide at high temperature. From our research on Pd-composite membrane, we have demonstrated that the new membrane has significantly higher hydrogen flux with very high perm-selectivity than any of the membranes commercially available. The steam reforming of methane by equilibrium shift in Pd-composite membrane reactor is being studied to demonstrate the potential application this new development. To …

This quarterly report documents significant achievements in the Enhanced Practical Photosynthetic CO{sub 2} Mitigation project during the period from 4/03/2001 through 7/02/2001. Most of the achievements are milestones in our efforts to complete the tasks and subtasks that constitute the project objectives. Note that this version of the quarterly technical report is a revision to add the reports from subcontractors Montana State and Oak Ridge National Laboratories The significant accomplishments for this quarter include: Development of an experimental plan and initiation of experiments to create a calibration curve that correlates algal chlorophyll levels with carbon levels (to simplify future experimental procedures); Completion of debugging of the slug flow reactor system, and development of a plan for testing the pressure drop of the slug flow reactor; Design and development of a new bioreactor screen design which integrates the nutrient delivery drip system and the harvesting system; Development of an experimental setup for testing the new integrated drip system/harvesting system; Completion of model-scale bioreactor tests examining the effects of CO{sub 2} concentration levels and lighting levels on Nostoc 86-3 growth rates; Completion of the construction of a larger model-scale bioreactor to improve and expand testing capabilities and initiation of tests; Substantial progress …

Congressional Research Service (CRS) report entailing information about Qualified Zone Academy Bonds vs. traditional tax-exempt bonds in regards to funding school renovations. The report goes over the side effects of the $1.6 billion Qualified Zone Academy Bond (QZAB), like revenue loss. Tables begin on page 4, and the report ends with a summary concluding that the QZAB program is more beneficial to tax payers and borrowers than traditional tax-exempt municipal bonds.

The U.S. tax code’s Foreign Sales Corporation (FSC) provisions provided a tax benefit for U.S. exporters. However, the European Union (EU) in 1997 charged that the provision was an export subsidy and thus contravened the World Trade Organization (WTO) agreements. A WTO ruling upheld the EU complaint, and to avoid WTO sanctioned retaliatory tariffs, U.S. legislation in November 2000 replaced FSC with the “extraterritorial income” (ETI) provisions, consisting of a redesigned export tax benefit of the same magnitude as FSC. The EU maintained that the new provisions are also not WTO-compliant and asked the WTO to rule on the matter.

This report discusses Amtrak, an intercity railway transit system that being operatios in 1971. Amtrak receives considerable criticism for its inability to make a profit. The central policy issue, which this report addresses, is the following: Given that a national system of passenger rail service appears to be inherently unprofitable, as is the case for other public services, do we as a Nation wish to preserve our system or to liquidate it?

The President of the United States has available certain powers that may be exercised in the event that the nation is threatened by crisis, exigency, or emergency circumstances (other than natural disasters, war, or near-war situations). Such powers may be stated explicitly or implied by the Constitution, assumed by the Chief Executive to be permissible constitutionally, or inferred from or specified by statute. Through legislation, Congress has made a great many delegations of authority in this regard over the past 200 years.
