Fusion reaction spectra produced by anisotropic fast ions in the PLT tokamak

Description: For beam-target fusion reactions, collimated measurements of the energy spectrum of one of the reaction products can provide information on the degree of anisotropy of the reacting beam ions. Measurements of the spectrum of 15 MeV protons produced by reactions between energetic /sup 3/He ions and relatively cold deuterons during fast wave minority heating in the PLT tokamak indicate that the velocity distribution of fast /sup 3/He ions is peaked perpendicular to the tokamak magnetic field.

HOTSPUR progress report: neutron source spectrum characterization, and /sup 6/Li(n,x. cap alpha. ) and /sup 7/Li(n,x. cap alpha. ) cross section determination

Description: As a prerequisite to high accuracy measurements involving the bulk configuration of /sup 6/LiD we must have a good grasp of the details of the RTNS-I neutron source energy spectrum. Experiments to this end involving neutron yield vs deuteron energy, ratios of foil activation of selected elements, and pulse height distributions of a Si surface barrier detector are described. With this knowledge, the /sup 4/He-production cross sections for /sup 6/Li and /sup 7/Li are found experimentally to be 0.… more

Chemical aspects of /sup 237/ Np Moessbauer spectroscopy

Description: The /sup 237/Np Moessbauer effect has been especially useful in studies of neptunium chemistry, by virtue of its excellent resolution and straightforward experimental techniques. Neptunium can have valences from +3 to +7, and a broad range of compounds can be prepared that are analogous to those of other actinide elements. Studies on neptunium compounds, for example, have a ready application to the analogous compounds of uranium and plutonium. The emphasis in this paper will be on the applicati… more

Neutron spectrum measurements using proton recoil proportional counters: results of measurements of leakage spectra for the Little Boy assembly

Description: Measurements of degraded fission-neutron spectra using recoil proportional counters are done routinely for studies involving fast reactor mockups. The same techniques are applicable to measurements of neutron spectra required for personnel dosimetry in fast neutron environments. A brief discussion of current applications of these methods together with the results of a measurement made on the LITTLE BOY assembly at Los Alamos are here described.

Pion production in heavy ion reactions near absolute thresholds

Description: Pion production in heavy ion collisions at energies below the free nucleon-nucleon threshold, i.e., at energies, where the pion mass exceeds the kinetic energy of a projectile nucleon in the zero momentum frame, has been discussed for a long time in terms of probing the intrinsic Fermi motion in the projectile and target nuclei. However, as the beam energy is lowered, this process gets more and more unlikely and below a certain energy it should not be observed anymore. In a sharp cut-off Fermi … more

Comparison of calculations and measurements of neutron leakage from the Little Boy replica

Description: Measurements of the neutron leakage spectra from 0.6 to 10 MeV are compared with several calculations and earlier measurements of coarse models of Little Boy. Results indicate excellent agreement except at the nose of the device where the neutron exit path is longer, and neutron streaming through geometric discontinuities may present problems. As a result of the agreement, the longstanding difference between calculations and measurements of the Ichiban critical asembly can be resolved: the resu… more

Edge region hydrogen line emission in the PDX tokamak

Description: Measurements of the H/sub ..cap alpha../ line shape and of the spatial distribution of the H/sub ..cap alpha../ emissivity in the PDX tokamak are interpreted in terms of molecular dissociation reactions at the plasma edge. The influx of molecules is shown to be roughly proportional to the edge emission intensity over a wide range of temperatures. The H/sub 2/ particle lifetime is estimated for various types of discharges in PDX.

Influence of materials and counting-rate effects on /sup 3/He neutron spectrometry

Description: The high energy resolution of the Cuttler-Shalev /sup 3/He neutron spectrometer causes spectral measurements with this instrument to be strongly susceptible to artifacts caused by the presence of scattering or absorbing materials in or near the detector or the source, and to false peaks generated by pileup coincidences of the rather long-risetime pulses from the detector. These effects are particularly important when pulse-height distributions vary over several orders of magnitude in count rate… more

Recent results from proton capture to giant resonances built on highly-excited states

Description: New measurements of the (p,..gamma..) reaction on natural targets of K and Ca at intermediate proton energies (E/sub p/ = 11 to 36 MeV) reveal excitation functions that are dominated by excited-state giant dipole resonances (ESGDR's) built upon single-particle states in /sup 40/Ca and /sup 41/Sc. These ESGDR's all peak near E/sub ..gamma../ = 20 MeV and have widths which increase monotonically with the final state's excitation energy. The integrated, inverse (..gamma..,P/sub 0/) cross sections … more

Investigations of molecular orbitals with accel-decel beams

Description: Quasimolecular transition energies can be found directly from the impact-parameter dependence of interference structure observed in measured K x-ray spectra. As these experiments require a K-vacancy bearing projectile at collision velocities small compared to the equivalent K-shell electron velocity, the accel-decel technique has to be used. Such an experiment was performed at the BNL Tandem Accel-Decel Facility for collisions of Cl/sup 16 +/ with Ar at energies ranging from 2.5 to 20 MeV. A ne… more

Use of the ORACLE DBMS in determining the response of complex scientific instrumentation

Description: In the Laser Fusion Program at Lawrence Livermore National Laboratory, a single laser fusion experiment lasts only a billionth of a second but in this time high speed instrumentation collects data that when digitized will create a data bank of several megabytes. This first level of data must be processed in several stages to put it in a form useful for interpretation of the experiments. One stage involves unfolding the source characteristics from the data and response of the instrument. This in… more
