An adaptive optic for correcting low-order wavefront aberrations (open access)

An adaptive optic for correcting low-order wavefront aberrations

Adaptive Optics used for correcting low-order wavefront aberrations were tested and compared using interferometry, beam propagation, and a far-field test. Results confirm that the design and manufacturing specifications were met. Experimental data also confirms theoretical performance expectations, indicating the usefulness of these optics (especially in a laser-beam processing system), and identifying the resulting differences between the two fabrication methods used to make the optics.

Air Quality and Motor Vehicles: An Analysis of Current and Proposed Emission Standards (open access)

Air Quality and Motor Vehicles: An Analysis of Current and Proposed Emission Standards

The extent to which emissions from motor vehicles and the amount of sulfur in commercial gasoline should be regulated has become a controversial issue. The EPA is proposing national limits on gasoline sulfur levels which would become effective in 2004. This report provides background information on the regulation of vehicle emissions in the United States, analyzes key elements of the National Low Emission Vehicle (LEV) program and the Environmental Protection Agency's (EPA) Tier 2 proposal, summarizes major views on the proposal that have been expressed by the automobile industry, the oil refining industry, and some environmental organizations, and discusses relevant legislative activity in the 106th Congress.

Animal Agriculture: Issues for the 106th Congress (open access)

Animal Agriculture: Issues for the 106th Congress

This report discusses a variety of animal agriculture issues that generated debate during the 106th Congress, including low livestock prices, especially for hogs. Economic difficulties have revived questions such as the impacts of consolidation in the livestock industry, and the price effects of animal imports from Canada and Mexico. This report also discusses a number of legislative proposals to assist livestock producers and enforce sanitary and phytosanitary standards, as well as continuing trade disputes and negotiations with China, the European Union, New Zealand, and Australia.

A Collective Impact Ionization Theory of Lock-On (open access)

A Collective Impact Ionization Theory of Lock-On

PhotoConductive semiconductor switches (PCSS's), such as optically-triggered GaAs switches, have been developed for a variety of applications. Such switches exhibit unique properties associated with lock-on, a phenomenon associated with bistable switching. In this paper lock-on is explained in terms of collective impact ionization.

[Comments on HCFA Medicare Integrity Program Operating Plans] (open access)

[Comments on HCFA Medicare Integrity Program Operating Plans]

Other written product issued by the General Accounting Office with an abstract that begins "GAO commented on the Health Care Financing Administration's (HCFA) plans for operating the Medicare Integrity Program (MIP), focusing on whether: (1) the law authorizing the MIP permits HCFA to assign responsibility for local Medicare coverage policy to the payment safeguard contractors (PSC) who will run the MIP under contract to HCFA; and (2) HCFA's proposed MIP regulations would provide an adequate legal basis for HCFA to conduct local policy-making through PSCs. GAO noted that HCFA reasonably interpreted the law to mean that its PSCs could set local Medicare coverage policy. GAO also noted that the proposed MIP regulations provide an adequate basis for HCFA's action."

Design and test of a beam transformer as a chopper (open access)

Design and test of a beam transformer as a chopper

This paper introduces a new type of chopper, which is similar to a beam transformer first discussed by R. Wideroe[1]. It is based on the fact that the RFQ has a rather small energy window. A pulsed beam transformer that provides 10% energy modulation to the beam in front of an RFQ can effectively chop the beam. It has fast rise- and fall-time and a short physical length. A prototype, which consists of a cavity and a high voltage pulsed power supply, has been constructed and tested. Two types of magnetic materials were tried for making the core of the cavity--the Finemet and the ferrite Philips 4M2. While the former gave good performance, the latter failed the test. Results from the bench measurements and a plan for beam tests are briefly described. For details the readers are referred to Ref. [2].

Distributed generation (open access)

Distributed generation

Distributed generation, locating electricity generators close to the point of consumption, provides some unique benefits to power companies and customers that are not available from centralized electricity generation. Photovoltaic (PV) technology is well suited to distributed applications and can, especially in concert with other distributed resources, provide a very close match to the customer demand for electricity, at a significantly lower cost than the alternatives. In addition to augmenting power from central-station generating plants, incorporating PV systems enables electric utilities to optimize the utilization of existing transmission and distribution.

Evaluation of Accident Frequencies at the Canister Storage Bldg (CSB)

By using the fault tree logic, an evaluation of the design basis accident frequencies at the Canister Storage Building has been performed. The evaluation demonstrates that due to low frequency of occurrences, the following design basis accidents are considered not credible (annual frequency of less than 10{sup -6}): Rearrangement of multidster overpack (MCO) internals; Gaseous release from the MCO; MCO internal hydrogen explosion; MCO external hydrogen explosion; Thermal runaway reactions inside the MCO; and Violation of design temperature criteria.
