A 2-D Self-Consistent DSMC Model for Chemically Reacting Low Pressure Plasma Reactors

Description: This paper will focus on the methodology of using a 2D plasma Direct Simulation Monte Carlo technique to simulate the species transport in an inductively coupled, low pressure, chemically reacting plasma system. The pressure in these systems is typically less than 20 mtorr with plasma densities of approximately 10{sup 17} {number_sign}/m{sup 3} and an ionization level of only 0.1%. This low ionization level tightly couples the neutral, ion, and electron chemistries and interactions in a system … more

ALARA{trademark} 1146 strippable coating

Description: Strippable or temporary coatings are innovative technologies for decontamination that effectively reduce loose contamination at low cost. These coatings have become a viable option during the deactivation and decommissioning of both US Department of Energy (DOE) and commercial nuclear facilities to remove or fix loose contamination on both vertical and horizontal surfaces. The ALARA{trademark} 1146 strippable coating was demonstrated as part of the Savannah River Site LSDDP and successfully rem… more

Alternative Fuel News, Vol. 2, No. 6

Description: The cover story in this issue of the Alternative Fuel News highlights the niche market principle; the places in which AFVs would best fit. This year's SEP funding is expected to be the springboard needed for the development of niche projects. The Clean Cities Program, by matching those needs and attributes in niches, can dramatically increase the attractiveness of AFVs and make an impact on those high-mileage, high-use fleets.

Application of Pauli-Villars Regularization and Discretized Light-Cone Quantization to a (3+1)-Dimensional Model

Description: We apply Pauli--Villars regularization and discrete light-cone quantization to the nonperturbative solution of a (3+1)-dimensional model field theory. The matrix eigenvalue problem is solved for the lowest-mass state with use of the complex symmetric Lanczos algorithm. This permits the calculation of each Fock-sector wave function, and from these we obtain values for various quantities, such as average multiplicities and average momenta of constituents, structure functions, and a form factor sl… more

Area Monitoring Dosimeter Program for the Pacific Northwest National Laboratory: Results for CY 1998

Description: In January 1993, Pacific Northwest National Laboratory (PNNL) established an area monitoring dosimeter program in accordance with Article 514 of the Department of Energy (DOE) Radiological Control Manual (RCM). The purpose of the program was to minimize the number of areas requiring issuance of personnel dosimeters and to demonstrate that doses outside Radiological Buffer Areas are negligible. In accordance with 10 CFR Part 835.402 (a)(1)-(4) and Article 511.1 of the RCM, personnel dosimetry sh… more

Atom trap trace analysis of krypton isotopes

Description: A new method of ultrasensitive isotope trace analysis has been developed. This method, based on the technique of laser manipulation of neutral atoms, has been used to count individual {sup 85}Kr and {sup 81}Kr atoms present in a natural krypton gas sample with isotopic abundances in the range of 10{sup {minus}11} and 10{sup {minus}13}, respectively. This method is free of contamination from other isotopes and elements and can be applied to several different isotope tracers for a wide range of a… more

Atomic Resolution Microscopy of Semiconductor Defects and Interfaces

Description: The optical arrangement of the scanning transmission electron microscope (STEM) allows formation of incoherent images by use of a large annular detector. Here we show this capability in the imaging of defects in GaN and the interfacial region of an Au/GaAs ohmic contact. A resolution of around 0.15 nm is attained. Such Z-contrast images show strong atomic number contrast and allow the probe to be positioned accurately at the defect or interface for the purpose of performing high spatial resolut… more

B {r_arrow} X{sub u} {ell} {bar {nu}}{sub {ell}} decay distributions to order {alpha}{sub s}

Description: An analytic result for the O({alpha}{sub s}) corrections to the triple differential B {r_arrow} X{sub u} {ell} {bar {nu}}{sub {ell}} decay rate is presented, to leading order in the heavy-quark expansion. This is relevant for computing partially integrated decay distributions with arbitrary cuts on kinematic variables. Several double and single differential distributions are derived, most of which generalize known results. In particular, an analytic result for the O({alpha}{sub s}) corrections … more

Calculated CIM Power Distributions for Coil Design

Description: Excessive bed expansion and material expulsion have occurred during experiments with the 3-inch diameter Cylindrical Induction Melter (CIM). Both events were attributed in part to the high power density in the bottom of the melter and the correspondingly high temperatures there. It is believed that the high temperatures resulted in the generation of gasses at the bottom of the bed which could not escape. The gasses released during heating and the response of the bed to gas evolution depend upon… more

Calculation of the Invariant Spin Field by Adiabatically Blowing Up the Beam With an RF Dipole

Description: The Relativistic Heavy Ion Collider RHIC will collide polarized proton beams up to a maximum beam energy of 250 GeV [1]. The invariant spin field in a high energy ring can vary substantially across the beam. This decreases the amount of polarization provided to experiments and makes the polarization strongly dependent on the position in phase space. This paper describes a method to compute the invariant spin field by adiabatically blowing up the beam with an rf dipole. This method will also all… more
