Implementations of the superhistory method
The superhistory method is incorporated, in different implementations, into two versions of MONK. In this paper the authors intercompare the efficiencies of these implementations via the Figure Of Merit (FOM), and compare the efficiencies of each with that of conventional Monte Carlo (MC). Finally, they suggest preferred versions of MC for eigenvalue calculations. Here, FOM {approx} 1/N{sigma}{sup 2}, where N is the number of histories, and {sigma} is the variance of a quantity of interest. In the criticality-safety version MONK, fission is simulated as suggested in Ref. 1 (Method-1). Every absorption site is a potential fission site, with weight W = {sigma}{sub f}/kx{sigma}{sub a}, where {sigma}{sub f} and {sigma}{sub a} are fission and absorption cross sections, and k is an estimate of the eigenvalue. If W < 1, W is taken as pf, the fission probability. A Method-1 fission produces, on average, {nu} offspring at each site. The reactor-physics MONK uses the standard MC fission treatment (Method-0), i.e. {nu}xW is the average number of neutrons born in a fission, and pf = 1. For consistency, they take absorption sites as potential fission sites in both methods. For v = 1 and a single generation per supergeneration, conventional and superhistory methods …

The KM phase in semi-realistic heterotic orbifold models
In string-inspired semi-realistic heterotic orbifolds models with an anomalous U(1){sub X},a nonzero Kobayashi-Masakawa (KM) phase is shown to arise generically from the expectation values of complex scalar fields, which appear in nonrenormalizable quark mass couplings. Modular covariant nonrenormalizable superpotential couplings are constructed. A toy Z{sub 3} orbifold model is analyzed in some detail. Modular symmetries and orbifold selection rules are taken into account and do not lead to a cancellation of the KM phase. We also discuss attempts to obtain the KM phase solely from renormalizable interactions.

FUNCTIONALIZED LATERAL SURFACE COATED LASERS FOR CHEM-BIO DETECTION
We present a class of compact, monolithic, photonic sensors consisting of multiple section edge emitting lasers with functionalized lateral surface coatings for low level detection of chemical or biological agents. Specifically, we discuss 8 {micro}m x 250 {micro}m Pd-coated H{sub 2} sensors and configurations to reduce the minimum detection limit from 138ppm for passive sensors to 1ppm for active sensors. Compared with conventional optical H{sub 2} sensors that use fiber gratings, surface plasmon resonances, or surface reflectance, our sensors offer the advantages of smaller size, wider dynamic range, monolithic integration of laser source and detector, and 2-D scalability to arrays of sensors that are functionalized to detect different agents.

Large-eddy simulation of very large kinetic and magnetic Reynolds number isotropic magnetohydrodynamic turbulence using a spectral subgrid model
A spectral subggrid-scale eddy viscosity and magnetic resisitivity model based on the eddy-damped quasi-normal Markovian (EDQNM) spectral kinetic and magnetic energy transfer presented in [12] is used in large-eddy simulation (LES) of large kinetic and magnetic Reynold number magneto-hydrodynamic (MHD) turbulence. The proposed model is assessed via a posteri tests on three-dimensional, incompressible, isotropic, non-helical, freely-decaying MHD turbulence at asymptotically large Reynolds numbers. Using LES with an initial condition characterized by an Alfv{acute e}n ratio of kinetic to magnetic energy {tau}{sub A} equal to unity, it is shown that at the kinetic energy spectrum E{sub K}(k) and magnetic energy spectrum E{sub M}(k) exhibit Kolmogorov -5/3 inertial subrange scalings in the LES, consistent with the EDQNM model.

SECONDARY ELECTRON EMISSION MEASUREMENTS FOR TIN COATING ON THE STAINLESS STEEL OF SNS ACCUMULATOR RING VACUUM CHAMBER.
BNL is responsible for the design and construction of the US Spallation Neutron Source (SNS) accumulator ring. Titanium Nitride (TiN) coating on the stainless steel vacuum chamber of the SNS accumulator ring is needed to reduce the secondary electron yield (SEY) and the undesirable resonant multiplication of electrons. The total SEY of TiN coated stainless steel material has been measured after coating samples were exposed to air and after electron and ion bombardment. We report here about TiN coating system setup at BNL and SEY measurements results at CERN, SLAC and KEK. We also present some simulation results of SNS accumulator ring electron-cloud effects using different SEY values.

RHIC OPERATION WITH LONGITUDINALLY POLARIZED PROTONS.
Polarized proton beams have been accelerated, stored and collided at 100GeV per beam in the Relativistic Heavy Ion Collider (RHIC) with longitudinal polarization. The essential equipment includes four Siberian snakes, eight spin rotators and fast relative polarimeters in each of the two RHIC rings as well as local polarimeters at the STAR and PHENIX detectors. This paper summarizes the performance of RHIC as a polarized proton collider in the FY03 run with emphasis on polarization issues. Preliminary data from the FY04 run is also shown.

Safety Report for Raman Spectroscopy: Safety Evaluation and Search Algorithm Enhancement
This study determines safety hazards associated with using a 300-mW 785-nm near-IR Raman laser for sample analysis. Most safety concerns are associated with excessive sample heating resulting from sample illumination. Thermography experiments were designed to quantitatively assess which visible surface colors heat most when exposed to the Raman laser. Temperatures achieved after illuminating 216 color patches with the unfocussed laser are presented. Figures contained in this report allow a field agent to rapidly determine the thermal hazards associated with Raman analysis of unknown colored samples. Dark colors tended to heat the most when exposed to the Raman laser. Studies were also conducted with a flammable organic solvent mixed with a near-IR absorbing dye to evaluate the magnitude of solution heating. Heating was minimal and Raman analysis was not considered a likely ignition hazard. The next series of experiments examined the tendency of propellants and military explosives, as well as mixtures of these explosives with IR-opaque dyes or matrix materials, to deflagrate upon illumination. All neat military explosives studied and most mixtures could be analyzed safely; however, an occasional mixture exhibited self-sustained deflagration, emphasizing safety hazards exist. Safety protocols include assessing the thermal consequences of sample analysis by referencing the thermography …

Collisional and Radiative Effects in Transient sub-Doppler Hole Burning: Double Resonance Measurements in CN
We report transient hole-burning and saturation recovery measurements in the CN radical with MHz frequency resolution and 20 ns time resolution. Narrow velocity groups of individual hyperfine levels of selected rotational states in CN (X{sup 2} {Sigma}{sup +}) are depleted and excited (A{sup 2}{pi}{sub i}) with a saturation laser and probed by a counterpropagating, frequency modulated probe beam. Recent work in our lab has used this method to measure and characterize the hyperfine splittings for a set of rotational, fine structure, and parity components of CN (A{sup 2}{pi}{sub i}, v=1). Extending this work, we report time and frequency dependence of the saturation signals following abrupt switching of the CW saturation beam on and off with an electro-optic amplitude modulator. Recovery of the unsaturated absorption following the turnoff of the saturation beam follows pressure-dependent kinetics, driven by collisions with the undissociated NCCN precursor with a rate coefficient of 2 x 10{sup -9} cm{sup 3} s{sup -1} molec{sup -1}. Similar recovery kinetics are observed for two-level saturation resonances, where the signal observed is a combination of X- and A-state kinetics, as well as for three-level crossover resonances, which can be chosen to probe selectively the holefilling in the X state or the …

A Low Noise RF Source for RHIC
The Relativistic Heavy Ion Collider (RHIC) requires a low noise rf source to ensure that beam lifetime during a store is not limited by the rf system. The beam is particularly sensitive to noise from power line harmonics. Additionally, the rf source must be flexible enough to handle the frequency jump required for rebucketing (transferring bunches from the acceleration to the storage rf systems). This paper will describe the design of a Direct Digital Synthesizer (DDS) based system that provides both the noise performance and the flexibility required.

User-Friendly End Station at the ALS for Nanostructure Characterization
This is a construction project for an end station at the ALS, which is optimized for measuring NEXAFS of nanostructures with fluorescence detection. Compared to the usual electron yield detection, fluorescence is able to probe buried structures and is sensitive to dilute species, such as nanostructures supported on a substrate. Since the quantum yield for fluorescence is 10{sup -4}-10{sup -5} times smaller than for electrons in the soft x-ray regime, such an end station requires bright undulator beamlines at the ALS. In order to optimize the setup for a wide range of applications, two end stations were built: (1) A simple, mobile chamber with efficient photon detection (>10{sup 4} times the solid angle collection of fluorescence spectrographs) and a built-in magnet for MCD measurements at EPU beamlines (Fig. 1 left). It allows rapid mapping the electronic states of nanostructures (nanocrystals, nanowires, tailored magnetic materials, buried interfaces, biologically-functionalized surfaces). It was used with BL 8.0 (linear polarized undulator) and BL 4.0 (variable polarization). (2) A sophisticated, stationary end station operating at Beamline 8.0 (Fig. 1 right). It contains an array of surface characterization instruments and a micro-focus capability for scanning across graded samples (wedges for thickness variation, stoichiometry gradients, and general …
