650 mm long liquid hydrogen target for use in a high intensity electron beam

Description: This paper describes a 650 mm long liquid hydrogen target constructed for use in the high intensity electron beam at the Stanford Linear Accelerator Center. The main design problem was to construct a target that would permit the heat deposited by the electron beam to be removed rapidly without boiling the hydrogen so as to maintain constant target density for optimum data taking. Design requirements, construction details and operating experience are discussed.

Actinide Production in the Reaction of Heavy Ions withCurium-248

Description: Chemical experiments were performed to examine the usefulness of heavy ion transfer reactions in producing new, neutron-rich actinide nuclides. A general quasi-elastic to deep-inelastic mechanism is proposed, and the utility of this method as opposed to other methods (e.g. complete fusion) is discussed. The relative merits of various techniques of actinide target synthesis are discussed. A description is given of a target system designed to remove the large amounts of heat generated by the pass… more

Actinide-specific complexing agents: their structural and solution chemistry

Description: The synthesis of a series of tetracatecholate ligands designed to be specific for Pu(IV) and other actinide(IV) ions has been achieved. Although these compounds are very effective as in vivo plutonium removal agents, potentiometric and voltammetric data indicate that at neutral pH full complexation of the Pu(IV) ion by all four catecholate groups does not occur. Spectroscopic results indicate that the tetracatecholates, 3,4,3-LICAMS and 3,4,3-LICAMC, complex Am(III). The Am(IV)/(III)-catecholat… more

Aging test results of an asphalt membrane liner

Description: The objective of the asphalt aging study described in this report was to determine the expected performance lifetime of a catalytically airblown asphalt membrane as a seepage barrier for inactive uranium mill tailings. The study, conducted by Pacific Northwest Laboratory for the Department of Energy's Uranium Mill Tailings Remedial Action Program, showed through chemical compatibility tests that the asphalt membrane is well suited for this purpose. The chemical compatibility tests were designed… more

Allowable Residual-Contamination Levels for Decommissioning Facilities in the 100 Areas of the Hanford Site

Description: This report contains the results of a study sponsored by UNC Nuclear Industries to determine Allowable Residual Contamination Levels (ARCL) for five generic categories of facilities in the 100 Areas of the Hanford Site. The purpose of this study is to provide ARCL data useful to UNC engineers in conducting safety and cost comparisons for decommissioning alternatives. The ARCL results are based on a scenario/exposure-pathway analysis and compliance with an annual dose limit for three specific mo… more

ArII - ArXVI produced in slow recoil collisions

Description: An atom in a gaseous target may be highly ionized in a single collision with a (very fast) very highly ionized projectile. A feature of the kinematics of the collision is that very little kinetic energy is imparted to the target atom. The ion is produced as a slow recoil. Typical recoil energies are 1 eV and change little with the degree of ionization produced in the target. This has several very attractive features as a spectroscopic source. First, the spectra are free from Doppler shifts whic… more

Assessment of factors affecting industrial electricity demand. Final report (revision version)

Description: In Chapter 2, we identify those factors affecting the industrial product mix - taste, relative output prices, and relative input prices - and isolate several determinants which have not been adequately accounted for to date in industrial electricity demand forecasts. We discuss how the lower energy prices of foreign producers affect domestic producers and how the growth in the number of substitutes for intermediate products such as steel and aluminum with plastics and composites affects the com… more

B vs H curves for 1008 and 1020 steels

Description: For the purpose of investigating the saturation regions, we have measured the B vs H curves for the purchased 1008 and 1020 steels. In order to make a fair representation, the sample was chosen under the following conditions: (1) it was taken far away from the flame cutting region; (2) a hand saw was used to cut off the sample; and (3) finally the sample was machined into a toroidal shape of about 2'' OD, 1.75'' ID and 1/2'' height. We fabricated two samples of each type of steel in order to ch… more

Basic data for thermal springs and wells as recorded in GEOTHERM: New Mexico

Description: GEOTHERM sample file contains 251 records for New Mexico. Three computer-generated indexes are found in appendices A, B, and C of this report. The indexes give one line summaries of each GEOTHERM record describing the chemistry of geothermal springs and wells in the sample file for New Mexico. Each index is sorted by different variables to assist the user in locating geothermal records describing specific sites. Appendix A is sorted by the county name and the name of the source. Also given are … more

Beam-beam interaction: luminosity, tails, and noise

Description: Observations of the beam-beam interaction at SPEAR, CESR, PETRA and PEP are discussed. They are sufficiently similar that a simple prescription can be formulated to describe the behavior of the luminosity as a function of current including the peak values. With this prescription the interpretation of various methods of increasing the luminosity, such as the reduction of the vertical betatron function, the increase of the horizontal beam size, and mini- and micro- beta projects, is straight-forw… more

Beam-blowup study for a weak-strong case

Description: A comparison is made of experimental results obtained on two SLAC storage rings PEP and SPEAR with the theoretical calculations and the dependence of the phenomenon on different machine parameters is studied. In the present paper we present such a comparison with reasonably good agreement between the experiment and the theory. The important conclusion from our study is that any valid theory of the beam-beam phenomenon should take into account the asymmetries of the machine parameters arising in… more

Biological testing and chemical analysis of process materials from an integrated two stage coal liquefaction: a status report

Description: Samples for chemical characterization and biological testing were obtained from ITSL runs 3LCF7, 3LCF8 and 3LCF9. Chemical analysis of these materials showed that SCT products were composed of fewer compounds than analogous materials from Solvent Refined Coal (SRC) processes. Major components in the SCT materials were three-, four-, five- and six-ring neutral polycyclic aromatic hydrocarbons (PAH). Methyl(C/sub 1/) and C/sub 2/ homologs of these compounds were present in relatively low concentr… more

Blowup of a weak beam due to interaction with a strong beam in an electron storage ring

Description: The theoretical description of the beam-beam interaction presented here takes into account all the important features of the beam-beam phenomenon: the nonlinear beam-beam force and its dependnce on both transverse coordinates, damping of the oscillations, presence of noise in the particle motion, in particular the quantum noise in its synchrotron radiation, actual machine functions, layout and the number B of interaction points, and to some extent imperfections present in the machine. The model… more

Brine migration test for Asse Mine, Federal Republic of Germany: final test plan

Description: The United States and the Federal Republic of Germany (FRG) will conduct a brine migration test in the Asse Salt Mine in the FRG as part of the US/FRG Cooperative Radioactive Waste Management Agreement. Two sets of two tests each will be conducted to study both liquid inclusion migration and vapor migration in the two salt types chosen for the experiments: (1) pure salt, for its characteristics similar to the salt that might occur in potential US repositories, and (2) transitional salt, for its… more

Catalytic gasification studies in a pressurized fluid-bed unit

Description: The purpose of the project is to evaluate the technical and economic feasibility of producing specific gas products via the catalytic gasification of biomass. This report presents the results of research conducted from October 1980 to November 1982. In the laboratory scale studis, active catalysts were developed for generation of synthesis gases from wood by steam gasification. A trimetallic catalyst, Ni-Co-Mo on silica-alumina doped with 2 wt % Na, was found to retain activity indefinitely for… more
