Particle fluxes and energy deposition in infinite homogeneous air due to protons of energy 1-, 5-, 10-, and 20-GeV

Description: Calculations have been carried out to determine the spatial dependence of the energy deposition and the spatial and energy dependence of particle fluxes in infinite homogeneous air without hydrogen due to protons of energy 5-, 10-, and 20-GeV. The fluxes are broken down into nine particle types. The energy deposition is divided among seven categories. The spatial dependence of the energy deposition is also presented for 1- and 10-GeV protons incident on infinite homogeneous air with hydrogen. T… more

Post-irradiation recovery of growth in Zircaloy. [Fast neutron irradiation]

Description: The previously reported model for fast neutron induced growth in Zircaloy has been modified to predict post-irradiation recovery of the growth. The predicted results are compared to growth recovery data obtained by Adamson. Agreement is good if the binding energy between vacancies and depleted zones is reduced from the in-pile value of 1.1 eV to a post-irradiation value of 1.0 eV. Such a reduction is reasonable.

Thermal-neutron-capture prompt-gamma emission spectra of representative coals. [1. 5 to 11 MeV]

Description: Prompt gamma ray emission spectra have been calculated from 1.5 to 11 MeV for a wide range of coal compositions exposed to a thermal neutron flux. These include contributions to the spectra from all of the major and minor elements present in the coals. Characteristics of the spectra are discussed and correlated with the coal compositions.

Retrieval of the energy spectrum in neutron TOF measurements

Description: The problem of retrieving the time dependence of the neutron energy spectrum from the detector current data in Faraday-cup experiments is studied. The time-dependent energy spectrum can be retrieved only when the neutron source in question meets a certain criterion. A detailed analytic formulation for the folding process is presented. The method that can be used to unfold the data in the retrievable case is explained in detail. 2 figures.

ICF diagnostics. Revision 1

Description: In the past several years there have been significant advances and accomplishments in the field of Inertial Confinement Fusion (ICF) research which are directly attributable to an active experimental program supported by the development and applications of sophisticated and specialized diagnostics instruments and techniques. The continued development of high temporal-and spatial-resolution diagnostics, although with a somewhat different technical emphasis than previously, is essential for maint… more

The mass, width, lifetime, and decay modes support the interpretation of a hadronically produced charm-strange baryon, the ..xi../sub c//sup +/. We present our preliminary measurements of the lifetime, and the ..lambda.., x/sub feynman,/ and p/sub t/ dependence of the state.

ENDF/B-5 fission product cross section evaluations

Description: Cross section evaluations were made for the 196 fission product nuclides on the ENDF/B-5 data files. Most of the evaluations involve updating the capture cross sections of the important absorbers for fast and thermal reactor systems. This included updating thermal values, resonance integrals, resonance parameter sets, and fast capture cross sections. For the fast capture results generalized least-squares calculations were made with the computer code FERRET. Input for these cross section adjustm… more

Neutron skyshine from end stations of the Continuous Electron Beam Accelerator Facility

Description: The MORSE{ }CG code from Oak Ridge National Laboratory was applied to the estimation of the neutron skyshine from three end stations of the Continuous Electron Beam Accelerator Facility (CEBAF), Newport News, VA. Calculations with other methods and an experiment had been directed at assessing the annual neutron dose equivalent at the site boundary. A comparison of results obtained with different methods is given, and the effect of different temperatures and humidities will be discussed.

Steady-state resistive toroidal-field coils for tokamak reactors

Description: If spatially-averaged values of the beta ratio can reach 5 to 10% in tokamaks, as now seems likely, resistive toroidal-field coils may be advantageous for use in reactors intended for fusion-neutron applications. The present investigation has parameterized the design of steady-state water-cooled copper coils of rectangular cross section in order to maximize figures of merit such as the ratio of fusion neutron wall loading to coil power dissipation. Four design variations distinguished by differ… more

Plasma Suppression of Large Scale Structure Formation in the Universe

Description: We point out that during the reionization epoch of the cosmic history, the plasma collective effect among the ordinary matter would suppress the large scale structure formation. The imperfect Debye shielding at finite temperature would induce a residual long-range electrostatic potential which, working together with the baryon thermal pressure, would counter the gravitational collapse. As a result the effective Jean's length, {tilde {lambda}}{sub J}, is increased by a factor, {tilde {lambda}}{s… more

Charm Spectroscopy at BaBar

Description: We present a mini-review on charm spectroscopy at the BABAR experiment. We first report on the c{bar s} meson spectrum, and present precise measurements of the D{sub s1}(2536) meson as well as the properties of the many new states discovered since 2003 (D*{sub s0}(2317), D{sub s1}(2460), D*{sub sJ}(2860), and D{sub sJ}(2700) mesons). We then discuss about charmed baryons observed recently in the BABAR experiment: {Omega}{sub c}{sup 0} and {Omega}*{sub c}{sup 0} css baryons, {Lambda}{sub c}(2940… more

D and B meson spectroscopy, new states, baryons at the Tevatron

Description: We review recent results in heavy quark hadron spectroscopy at the Tevatron. With increasing data samples, the Tevatron experiments start to uncover information on the spectroscopy of b-hadrons. Most important are the first observations of the narrow B**{sub s}{sup 0} as well as {Sigma}{sub b}{sup {+-}}, {Sigma}*{sub b}{sup {+-}} and {Xi}{sub b}{sup -} baryons. In addition we present updated results on the narrow B**{sup 0} and B{sub c} mesons.

A Measurement of the Lifetime of the Lambda_b Baryon with the CDF Detector at the Tevatron Run II

Description: In March 2001 the Tevatron accelerator entered its Run II phase, providing colliding proton and anti-proton beams with an unprecedented center-of-mass energy of 1.96 TeV. The Tevatron is currently the only accelerator to produce {Lambda}{sub b} baryons, which provides a unique opportunity to measure the properties of these particles. This thesis presents a measurement of the mean lifetime of the {Lambda}{sub b} baryon in the semileptonic channel {Lambda}{sub b}{sup 0} {yields} {Lambda}{sub c}{s… more

B Hadron properties measured in the D0 experiment

Description: The study of charm and beauty mesons and baryons provides many opportunities to not only measure and classify their spectroscopic states, but also it serves as a testing ground for aspects of flavor QCD such as heavy quark effective theory and lattice gauge calculations, that are used in precise calculations of masses, lifetimes and cross sections. The Fermilab Tevatron has provided both fixed target and proton--antiproton collider facilities that not only account for the discovery of b-quarks … more

Experimental investigation of the production of glueballs and meson resonance states

Description: We have made striking and considerable progress in our AGS program which is searching for a Quark-Gluon Plasma or other new phenomena at the AGS. We are employing a TCP Tracking Magnetic Spectrometer that has handled up to {approx}100 tracks, the maximum observed in 14.5 GeV/c {times} A Si ions incident on Au and Cu. In essence the TPC covers more than the forward half hemisphere in the nucleon-nucleon cms (i.e. {ge} 2{pi}) and thus allows tracking, momentum and angular analysis of the charged … more
