18t Resistive Magnet Development. Conceptual Design Second Annual Report

Description: This report documents the work performed on a normal conducting magnet during fiscal year 1985. Emphasis, during the study, was on refinement of the structural design and optimization of the coil current density distribution for either maximum field generation or minimum power consumption. The results have shown that one can generate a 4.4 tesla field using 6.14 megawatts or 3.1 tesla at 1.43 megawatts. The structural design has been modified to stiffen the outer turn of the conductor. The modi… more

3Q120 Low Gradient Behaviour

Description: Three 3Q120 magnets--representative of those in the AP 1 line--have been measured with a harmonics probe at MDTF at both low (0-48 A) and high (to >= 400 A). The intent of the measurements was to learn their behavior at the low gradients necessary to transport 8 Gev antiprotons back through the AP 1 line for injection into the Main Ring (and subsequently the superconducting ring--see Ref. 1). Many of the measurements have been preceded by remnant field biasing ramps to 148, 270, 295, or 405 … more

The intent of the measurements was to learn their behavior at the low gradients necessary to transport 8 Gev antiprotons back through the AP 1 line for injection into the Main Ring. This paper describes some aspects of the measurements that were not included in the main paper, in order to keep the size of the main report reasonably smal… more

Accelerators for heavy ion fusion

Description: Large fusion devices will almost certainly produce net energy. However, a successful commercial fusion energy system must also satisfy important engineering and economic constraints. Inertial confinement fusion power plants driven by multi-stage, heavy-ion accelerators appear capable of meeting these constraints. The reasons behind this promising outlook for heavy-ion fusion are given in this report. This report is based on the transcript of a talk presented at the Symposium on Lasers and Parti… more

Assessment of the important radionuclides in nuclear waste

Description: The relative importance of the various radionuclides contained in nuclear waste has been assessed by consideration of (1) the quantity of each radionuclide present, (2) the Environmental Protection Agency`s release limits for radionuclides, (3) how retardation processes such as solubility and sorption affect radionuclie transport, and (4) the physical and chemical forms of radionuclides in the waste. Three types of waste were reviewed: spent fuel, high-level waste, and defense high-level waste.… more

Catalytic gasification of bagasse for the production of methanol

Description: The purpose of the study was to evaluate the technical and economic feasibility of catalytic gasification of bagasse to produce methanol. In previous studies, a catalytic steam gasification process was developed which converted wood to methanol synthesis gas in one step using nickel based catalysts in a fluid-bed gasifier. Tests in a nominal 1 ton/day process development unit (PDU) gasifier with these same catalysts showed bagasse to be a good feedstock for fluid-bed gasifiers, but the catalyst… more

Characterization of the solid, airborne materials created when UF/sub 6/ reacts with moist air flowing in single-pass mode

Description: A series of experiments has been performed in which UF/sub 6/ was released into flowing air in order to characterize the solid particulate material produced under non-static conditions. In two of the experiments, the aerosol was allowed to stagnate in a static chamber after release and examined further but in the other experiments characterization was done only on material collected a few seconds after release. Transmission electron microscopy and mass measurement by cascaded impactor were used… more

Comparison of the CRAY X-MP-4, Fujitsu VP-200, and Hitachi S-810/20 : an Argonne Perspective

Description: A set of programs, gathered from major Argonne computer users, was run on the current generation of supercomputers: the CRAY X-MP-4, Fujitsu VP-200, and Hitachi S-810/20. The results show that a single processor of a CRAY X-MP-4 is a consistently strong performer over a wide range of problems. The Fujitsu and Hitachi excel on highly vectorized programs and offer an attractive opportunity to sites with IBM-compatible computers.

Confinement scaling and ignition in tokamaks

Description: A drift wave turbulence model is used to compute the scaling and magnitude of central electron temperature and confinement time of tokamak plasmas. The results are in accord with experiment. Application to ignition experiments shows that high density (1 to 2) . 10/sup 15/ cm/sup -3/, high field, B/sub T/ > 10 T, but low temperature T approx. 6 keV constitute the optimum path to ignition.

Convergence of a random walk method for the Burgers equation

Description: In this paper we consider a random walk algorithm for the solution of Burgers' equation. The algorithm uses the method of fractional steps. The non-linear advection term of the equation is solved by advecting ''fluid'' particles in a velocity field induced by the particles. The diffusion term of the equation is approximated by adding an appropriate random perturbation to the positions of the particles. Though the algorithm is inefficient as a method for solving Burgers' equation, it does model … more

Corrosion Protection of Arctic Offshore Structures: Final Report. [Effects of Temperature and Salinity on Required Cathodic Protection Current]

Description: Results are presented for a research program on corrosion prevention for Arctic offshore structures which are in contact with sea ice for a significant portion of the year. The electrical method most adaptable for structure protection involves the injection of impressed current from several remote anodes buried just beneath the sea floor. The electrical resistivity of annual sea ice as a function of temperature and salinity is presented. Details of the interface layers formed between sea ice an… more

Cryogenic explosion environment modeling and testing of space shuttle and light-weight radioisotope heater unit interactions

Description: In order to assess the risk to the world's populace in the event of a Space Shuttle accident when radioisotope-containing heat sources are on board, testing of that system must be performed to determine release point, environments required, and the size distribution of the released fuel. To evaluate the performance of the Light-Weight Radioisotope Heater Unit (LWRHU) (101 of these 1-W items are placed on the Galileo spacecraft which will be launched from the Space Shuttle), some high-velocity i… more

Detailed conceptual design of a high temperature CO/sub 2/ sensor for geothermal brine. Final report, Task II

Description: The Task I pCO/sub 2/ sensor was evaluated in the laboratory and improvements incorporated. Of special note was the redesign of the internal reference electrode which offered greater stability, and improved reliability - a design both smaller and more simple. The ISFET sensor was improved by using a new sensing material which afforded better speed of response. The H/sub 2/S getter was redesigned to overcome seal problems encountered in early Task II tests. The improved probe was thoroughly test… more

Discrete-coil investigations of modular stellarator configurations

Description: The existence of a vacuum magnetic well is generally accepted as a prerequisite to start-up. The special set of modular-stellarator configurations selected for the present computational investigation was derived from coefficients and equations that produced finite-beta wells in a continuous-current-sheet representation. The corresponding coils did not produce magnetic wells in a vacuum when their field configuration was investigated with a discrete-coil code. Vacuum magnetic wells have been ide… more

Discussion of material rotation and stress rate

Description: Characterization of material behavior can be divided into two parts, the analysis of deformation and the underlying physics, though these are intimately related. A significant advance in the analysis of deformation was made when the polar decomposition theorem was introduced, making it possible to separate large deformations into a stretch and a rotation. Consequences of the theorem affect the way rate processes should be characterized. In particular, rate of material rotation is different from… more
