Amplifier-Discriminator-Multiplexor card

Description: The Amplifier-Discriminator-Multiplexor (ADM) card described was designed for the External Muon Identifier at the 15 ft Bubble Chamber. The general scheme of the data readout of the External Muon Identifier is based on the use of a master clock. The ADM card serves to amplify the signals from the proportional tubes, discriminate them, latch the signals in parallel into a shift register. The data are then shifted out serially to the Time Digitizing System, using the master clock. The shift regis… more

Angular distribution of power from an undulator and a wiggler on a 6-GeV storage ring

Description: There are two fundamental reasons to have a full knowledge of the angular distribution of power from an insertion device: 1. To evaluate the heat-load distribution on the first optical element in a beamline. 2. To estimate the total radiated power which will impinge on the walls of an insertion device. This is important to ensure needed cooling of the insertion device walls. The photodesorption is another closely related phenomenon determined by the exposure of the insertion device walls to the… more

Anomalous thermal confinement in ohmically heated tokamaks

Description: A model is proposed to explain the behavior of the gross energy confinement time in ohmically heated tokamak plasmas. The analysis takes into account the effect of the anomalous thermal conductivity due to small scale turbulence and of the macroscopic MHD behavior, which provides some constraints on the temperature profile. Results indicate that the thermal conductivity associated with the dissipative trapped-electron mode and with the ion temperature gradient (eta/sub i/) mode can account, res… more

Bio-leaching of toxic metals from geothermal waste. A preliminary engineering analysis

Description: The feasibility of a biological facility to treat geothermal sludge from a base case 50-MW double-flash geothermal power plant in the Imperial Valley, California was evaluated. The effect of sludge and nutrient concentration, agitation air bubbling and sterility on the rate of metal solubilization by the bacteria Thiobacillus thiooxidans and ferrooxidans was examined. All experiments were performed in batch flasks and monitored daily for bacterial growth. T. Thiooxidans leached 36% of the zinc … more

Bowing of solid breeder fuel pins and multiplier rods in a pin-type fusion blanket

Description: The most important outcome of this bowing analysis is the determination of the number of internal breeder rod supports required for good thermal performance. Although many effects were considered, the swelling deformations were the most restrictive in terms of the peak deflections. It appears that three internal supports should be sufficient to keep the rod bowing below acceptable levels without significantly raising the structure-to-breeder ratio. The most severe interaction problem involved t… more

Chemical Profiles of Microalgae with Emphasis on Lipids: Final Report

Description: This final report details progress during the third year of this subcontract. The overall objective of this subcontract was two fold: to provide the analytical capability required for selecting microalgae strains with high energy contents and to develop fundamental knowledge required for optimizing the energy yield from microalgae cultures. The progress made towards these objectives during this year is detailed in this report.

Comparison of collision operators for drift and MHD-interchange modes in unsheared slab geometry

Description: The general procedure for the kinetic analysis of low-frequency electrostatic and electromagnetic modes in toroidal geometry is now well known. In the collisionless limit, the relevant dynamics (e.g., trapped particles, resonances, etc.) can be treated appropriately. However, with the introduction of collisional effects, it is customary, for tractability, to employ model collision operators which do not rigorously satisfy all conservation properties of more exact collision operators. Insight in… more

Comparison of two-dimensional and three-dimensional MHD equilibrium and stability codes

Description: Stability results obtained with the fully three-dimensional magnetohydrodynamic code BETA, the helically invariant code HERA, and the asymptotic stellarator expansion code STEP agree well for a straight l = 2, M = 5 stellarator model. This good agreement between the BETA and STEP codes persists as toroidal curvature is introduced. This validation provides justification for confidence in work with these models. 20 refs., 11 figs.

Comparisons of Yield Calculations with Data

Description: Given what is claimed to a reasonably accurate technique for calculating the pbar yield, it is useful to ask for comparisons with the data available from the recent commissioning run. The simplest comparison to make is that of the yield. The number of pbars circulating in the Debuncher was measured many times; the total number of secondaries at IC728 in AP-2 was also measured many times. The ratio of pbars to total flux at IC728 was measured once (Bk. I, p 166); this number was {bar P}/total = … more

Consolidation and shear failure leading to subsidence and settlement. Final report

Description: Subsidence and settlement are phenomena that are much more destructive than generally thought. In shallow land burials they may lead to cracking of the overburden and eventual exposure and escape of waste material. The primary causes are consolidation and cave-ins. Laboratory studies performed at Los Alamos permit us to predict settlement caused by consolidation or natural compaction of the crushed tuff overburden. We have also investigated the shear failure characteristics of crushed tuff that… more

Cost study of the ESPRESSO blanket for a Tandem Mirror Reactor

Description: A detailed cost study of the ESPRESSO blanket concept for the Tandem Mirror Fusion Reactor (TMR) has been performed to complement the thermal-hydraulic parametric study and to help narrow down the choice of parameters for the final design. The ESPRESSO blanket consists of a number of structurally independent ring modules. Each ring module is made up of a number of mutually pressure-supporting canisters containing arrays of breeder tubes. Two separate helium coolant flows are used: a main flow t… more

Decays of the tau lepton

Description: Previous measurements of the branching fractions of the tau lepton result in a discrepancy between the inclusive branching fraction and the sum of the exclusive branching fractions to final states containing one charged particle. The sum of the exclusive branching fractions is significantly smaller than the inclusive branching fraction. In this analysis, the branching fractions for all the major decay modes are measured simultaneously with the sum of the branching fractions constrained to be on… more

Density effects on sawtooth oscillations for high-theta 120 kA discharges in ZT-40M

Description: The effects of using pulse discharge cleaning and neutral gas refueling to increase the plasma density for 120 kA high-theta discharges on ZT-40M have been studied. Experimentally, increasing the plasma density quenches the sawtooth oscillations. Theoretical analysis indicates that the likely reason for this observation is that increasing the plasma density lowers the on-axis streaming parameter which in turn flattens the effective resistivity profiles leading to smaller (or nonexistent) sawtoo… more

Detection of surface glow related to spacecraft glow phenomenon

Description: We have developed a high flux source of low energy neutral beams to study the spacecraft glow phenomena by using a biased limiter to neutralize plasma in ACT-1. Beams of nitrogen and nitrogen-oxygen mixtures with energies of 1 to 15 eV and fluxes greater than or equal to 10/sup 14//cm/sup 2//s were directed on target surfaces consisting of Z-302 and Z-306 paints. With the nitrogen beams we successfully detected a glow due to beam-surface interactions. In addition, we discovered a volume glow ef… more
