3D simulations of axially confined heavy ion beams in round and square pipes

Description: We have been using the 3d PIC code WARP6 to model the behavior of beams in a heavy ion induction accelerator; such linacs are candidates for an ICF driver. Improvements have been added to the code to model an axially confined beam using comoving axial electric fields to simulate the confining ears'' applied to the accelerating pulses in a real system. We have also added a facility for modeling a beam in a round pipe, applying a capacity matrix to each axial Fourier mode in turn. These additions… more

Accessing the Inaccessible: The Case for Opening up Russia's Closed Cities

Description: The selling of weapons-related nuclear knowledge by Russian scientists for economic gain constitutes a threat to US national security. Some estimate that the number of Russian scientists seeking permanent employment abroad constitute five to ten percent of all researchers who have left the field of science. And, there is concern that those who have left are ''the better minds.'' Moreover, the issue of brain drain concerns not only those who move abroad permanently, but those who still reside in… more

Active RF Pulse Compression Using Electrically Controlled Semiconductor Switches

Description: In this paper, we present the recent results of our research on the ultra-high power fast silicon RF switch and its application on active X-Band RF pulse compression systems. This switch is composed of a group of PIN diodes on a high purity silicon wafer and has achieved a switching time of 300ns. The wafer is inserted into a cylindrical waveguide operating in the TE01 mode. Switching is performed by injecting carriers into the bulk silicon through a high current pulse. The RF energy is stored … more

Administrative Agencies and Claims of Unreasonable Delay: Analysis of Court Treatment

Description: This report discusses judicial remedies available for delayed agency actions that are somewhat limited. Generally, a court is restricted to ordering an agency to act by a specific deadline. The following sections outline the timing requirements imposed by the Administrative Procedure Act (APA), discuss the available judicial remedies when actions are found to be unreasonably delayed, and provide an examination of cases where courts have been asked to compel agency action. Finally, the report co… more

Advances in HFE Methods and Their Implications for Regulatory Reviews.

Description: There is renewed interest in the United States (U.S.) to construct new Generation III and III+ reactors within the next decade and Generation IV reactors in the future. Licensing by the U.S. Nuclear Regulatory Commission (NRC) is a significant consideration and these new plants may pose new challenges. One such challenge is the advances in human factors engineering (HFE) methods that are used. These methods are used to design and evaluate the HFE aspects of a plant, such as the human-system int… more

AN ALGOL 60 SYNTAX CHECKER FOR THE IBM 7090 COMPUTER

Description: A syntax checker was designed based on the syntax of Algol as previously described. It was desirable to design the syntax checker as a set of mutually recursive processors tied together by building blocks which perform certain bookkeeping functions. Because of the recursive nature of the language and of the syntax checker, the problem of recovery after an error required much attention. A method was devised which permits most programs to be checked completely despite errors. The syntax checker w… more

Ambulatory Research and Education Center Oregon Health Science University. Environmental Assesment

Description: DOE has prepared an Environmental Assessment (EA) (DOE/EA-0921) evaluating the proposed construction and operation of the Ambulatory Research and Education Center (AREC), which would be located on the top seven floors of the existing NeuroSensory Research Center (NRC) on the campus of the Oregon Health Sciences University (OHSU) at Portland, Oregon. The proposed action would combine activities scattered across the campus into a central facility. Based on the analysis in the EA, DOE has determin… more

Analysis and Mitigation of X-Ray Hazard Generated From High Intensity Laser-Target Interactions

Description: Interaction of a high intensity laser with matter may generate an ionizing radiation hazard. Very limited studies have been made, however, on the laser-induced radiation protection issue. This work reviews available literature on the physics and characteristics of laser-induced X-ray hazards. Important aspects include the laser-to-electron energy conversion efficiency, electron angular distribution, electron energy spectrum and effective temperature, and bremsstrahlung production of X-rays in t… more

Analysis of hazardous biological material by MALDI mass spectrometry

Description: Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-MS) has become a valuable tool for analyzing microorganisms. The speed with which data can be obtained from MALDI-MS makes this a potentially important tool for biological health hazard monitoring and forensic applications. The excitement in the mass spectrometry community in this potential field of application is evident by the expanding list of research laboratories pursuing development of MALDI-MS for bacteri… more

Analysis of nanometer-scale precipitation in a rapidly solidified stainless steel

Description: The authors have rapid-solidification-processed many stainless steels by gas atomization and achieved strength improvements of over 50% relative to conventionally-processed stainless steels with concomitant improvement in corrosion and oxidation behavior. These strength improvements are most pronounced after aging treatments when elevated concentrations of oxygen and vanadium are present in the stainless steel. An austenitic (FCC) stainless steel was prepared by gas atomization and consolidated… more

An analysis of once-per-revolution oscillating aerodynamic thrust loads on single-rotation propellers on tractor airplanes at zero yaw

Description: A simplified procedure is shown for calculating the once-per-revolution oscillating aerodynamic thrust loads on propellers of tractor airplanes at zero yaw. The only flow field information required for the application of the procedure is a knowledge of the upflow angles at the horizontal center line of the propeller disk. Methods are presented whereby these angles may be computed without recourse to experimental survey of the flow field. The loads computed by the simplified procedure are compar… more

Ancient nature of alternative splicing and functions of introns

Description: Using four genomes: Chamydomonas reinhardtii, Agaricus bisporus, Aspergillus carbonarius, and Sporotricum thermophile with EST coverage of 2.9x, 8.9x, 29.5x, and 46.3x respectively, we identified 11 alternative splicing (AS) types that were dominated by intron retention (RI; biased toward short introns) and found 15, 35, 52, and 63percent AS of multiexon genes respectively. Genes with AS were more ancient, and number of AS correlated with number of exons, expression level, and maximum intron l… more

Anisotropic Elastic Scattering of Neutrons

Description: In an elastic collision the neutron loses part of its kinetic energy to the nucleus with both the kinetic and momentum of the system being conserved. However, for many elements the scattering is not isotropic in the center-of-mass system at the higher neutron energies. Many of the present reactor multigroup codes include anisotropic scattering at the high neutron energies, while many others assume isotropic scattering at all energies. In order to consider some of the effects of including anisot… more
