Neutral Currents - The Structure of the Coupling

Description: The authors report here on latest results from an investigation of the form of the neutral current coupling in the inclusive channels {nu}{sub {mu}} + N {yields} {nu}{sub {mu}} + hadrons and {bar {nu}}{sub {mu}} + N {yields} {bar {nu}}{sub {mu}} + hadrons. The experiment was conducted by the Caltech-Fermilab group in October 1974. The data were taken in the Fermilab narrow band beam set to a mean secondary hadron energy of {+-} 170 GeV. The distributions of total energy, observed in the target … more

Partitioning of actinide elements from high-level waste using laser photochemical methods

Description: The feasibility of photochemically fractionating the actinides in nuclear waste processing has been evaluated on a preliminary basis. The data indicate that there are potentially useful photo-redox reactions. However, there is a serious lack of data on photochemical parameters for the solutions conditions which exist in nuclear waste processing. The problem areas relevant to photochemical processing are identified. The experimental areas which must be investigated in order to further evaluate t… more

Transport aspects of electrochemical machining and electrometallurgy

Description: Transport processes in large measure determine the rate at which electrolytic metal deposition and dissolution can be conducted. Unusually high rates, often accompanied by the formation of solid reaction products, are achieved in electrochemical machining by the use of high electrolyte flow velocities between closely-spaced electrodes. Geometrical shape and surface finish resulting from deposition or dissolution reactions are determined by the current distribution on a macroscopic and microscop… more

Laser beam trapping and propagation in cylindrical plasma columns

Description: An analysis of the scheme to heat magnetically confined plasma columns to kilovolt temperatures with a laser beam requires consideration of two propagation problems. The first question to be answered is whether stable beam trapping is possible. Since the laser beam creates its own density profile by heating the plasma, the propagation of the beam becomes a nonlinear phenomenon, but not necessarily a stable one. In addition, the electron density at a given time depends on the preceding history o… more

Bell's theorem without hidden variables

Description: The CHSH inequality is demonstrated from locality alone without using either determinism or the concept of hidden variables. Then a comment is made about the violation of this inequality by quantum theory. (JFP)

Thermal decomposition and reaction of confined explosives. [TNT, TATB, LX-04, LX-10]

Description: Some new experiments designed to accurately determine the time interval required to produce a reactive event in confined explosives subjected to temperatures which will cause decomposition are described. Geometry and boundary conditions were both well defined so that these experiments on the rapid thermal decomposition of HE are amenable to predictive modelling. Experiments have been carried out on TNT, TATB and on two plastic-bonded HMX-based high explosives, LX-04 and LX-10. When the results … more

Working model for Ge(Li) detector counting efficiencies

Description: A practical model has been developed that is capable of describing the overall Ge(Li) detection efficiency as a function of several known or measurable parameters such as gamma-ray energy, source-to-detector distance, detector dimensions, source extension (area and volume), source composition, and external absorbers. The algorithms of this model permit the evaluation of a large variety of sample shapes, sizes, material compositions, and source strengths with a single initial detector calibratio… more

Determination of dibutylbutylphosphonate in the presence of tributylphosphate by gas liquid chromatography

Description: A gas chromatographic determination of dibutylbutyl-phosphonate in the presence of tributylphosphate was developed. The separation was done on a 183 cm by 3 mm stainless steel column packed with 10 percent Carbowax 20M--TPA on 80/100 mesh Chromosorb W AW and detected by flame ionization. A nitrogen carrier gas flow of 40 cm/sup 3//min and an oven temperature of 180/sup 0/C produced optimum resolution and column efficiency. The use of temperature programming reduced retention times and thus anal… more

Quality assurance for systems at the Lawrence Livermore Laboratory tritium facility

Description: A quality-assurance program for tritium-handling systems at the Lawrence Livermore Laboratory tritium facility has been developed. Operational guidelines governing system design, construction, and testing have been written. A certified-material storeroom has been established to procure and distribute high-quality materials. Ten systems are currently being modified under the new guidelines.

Tests of Unitarity

Description: Various tests of unitarity are briefly reviewed. It is concluded that there is consistency with quantum theory and that similar tests could be made in many other multipurpose experiments, especially those of much higher energies. (JFP)

Studies of exotic light nuclei

Description: For neutron-deficient nuclei, extension of the T/sub z/ = --3/2 series of strong beta-delayed proton precursors to /sup 61/Ge is discussed. For neutron-excess nuclei, heavy-ion induced, multi-nucleon transfer reaction studies of masses and energy levels of 2sld shell nuclei with T/sub z/ greater than or equal to 5/2 are covered. In addition, preliminary attempts to employ the (/sup 7/Li,/sup 2/He) reaction for the latter studies are shown; a new detection system capable of observing unbound fin… more

Focusing lenses for the 20-beam fusion laser, SHIVA

Description: The focus lens design for the 20-beam SHIVA laser fusion facility involves considerations of uniform and normal pellet illumination. The resulting requirements dictate tailored beam intensity profiles and vacuum-loaded thin lenses.

Assessment of a chemical getter for scavenging tritium from an inert gas

Description: Results are presented of a study aimed at determining the feasibility of using chemical getter beds to scavenge tritium from inert gases. Two types of getter bed, fixed and fluidized, were considered, using cerium as the getter material. Mathematical-modeling results and capital-cost estimates indicate that not only is the gettering approach technically feasible, it could lead to considerable cost savings over catalytic oxidation, the tritium-removal method traditionally used.

Large high current density superconducting solenoids for use in high energy physics experiments

Description: Very often the study of high energy physics in colliding beam storage-rings requires a large magnetic field volume in order to detect and analyze charged particles which are created from the collision of two particle beams. Large superconducting solenoids which are greater than 1 meter in diameter are required for this kind of physics. In many cases, interesting physics can be done outside the magnet coil, and this often requires that the amount of material in the magnet coil be minimized. As a… more

Laser fusion overview. [Forecasting of laser fusion feasibility]

Description: Because of recent breakthroughs in the target area, and in the glass laser area, the scientific feasibility of laser fusion--and of inertial fusion--may be demonstrated in the early 1980's. Then the development in that time period of a suitable laser (or storage ring or other driving source) would make possible an operational inertial fusion reactor in this century. These are roughly the same time scales as projected by the Tokamak magnetic confinement approach. It thus appears that the 15-20 y… more

Adhesion of electrodeposited coatings on U--Ti and Mulberry

Description: Quantitative test data are presented for two etched and plated uranium alloys, U-0.75 Ti and mulberry (U-7.5 Nb, 2.5 Zr). Conical head tensile tests showed that the bond between nickel plating and U--Ti was stronger than that between nickel plating and mulberry. Ring shear tests showed that electroplated nickel coatings are more adherent than other coatings applied to U--Ti. Utilizing a newly developed etchant for mulberry, large cylinders of this material were joined to aluminum and then tensi… more

Laser-start-up system for magnetic mirror fusion

Description: A CO/sub 2/ laser system has been developed at LLL to provide hot start-up plasmas for magnetic mirror fusion experiments. A frozen ammonia pellet is irradiated with a laser power density in excess of 10/sup 13/ W/cm/sup 2/ in a 50-ns pulse. This system uses commercially available laser systems. Optical components were fabricated both by direct machining and standard techniques. The technologies used in this system are directly applicable to reactor scale systems.
