Analysis of long pulse physics experiments at LLL: Late 1977-Early 1979

Description: In the two years since the last Gordon Conference, we have shifted our interest in laser-plasma interactions to the long pulse (1 ns) regime on the Argus facility.

Waste management analysis for the nuclear fuel cycle: actinide recovery from combustible waste, October 1977-March 1978

Description: Evaluation of the Ce(IV)-NHO/sub 3/ system for recovery of actinides from incinerator ash is continuing. High-fired americium-traced plutonium oxide was completely solubilized in this system and recovery of actinides from incinerator ash was greater than or equal to 95%. Recovery of solubilized plutonium was done by solvent extraction using tributyl phosphate. Tervalent actinides will be recovered by a bidentate organophosphorus solvent extractant. The Ce(IV)-HNO/sub 3/ system was compared with… more

Identification, detection, and validation of vibrating structures: a signal processing approach

Description: This report discusses the application of modern signal processing techniques to characterize parameters governing the vibrational response of a structure. Simulated response data is used to explore the feasibility of applying these techniques to various structural problems. On-line estimator/indentifiers are used to estimate structural parameters, validate designed structures, and detect structural failure when used with a detector.

Application of Time Domain PARET to the measured responses of a building

Description: The application of the Time Domain PARET (TDP) algorithm to data obtained from the measured responses of a three story reinforced concrete building approximately 465 feet long by 220 feet wide by 40 feet high, with 12 to 18 inch thick walls, is described. The measurements were taken by Agbabian Associates, El Segundo, California. The structure was excited by a device developed at Agbabian that uses a mass sliding down a rod to cut metal disks attached to the rod. The result is a series of impul… more

West Texas geothermal resource assessment. Part II. Preliminary utilization assessment of the Trans-Pecos geothermal resource. Final report

Description: The utilization potential of geothermal resources in Trans-Pecos, Texas was assessed. The potential for both direct use and electric power generation were examined. As with the resource assessment work, the focus was on the Hueco Tanks area in northeastern El Paso County and the Presidio Bolson area in Presidio County. Suitable users of the Hueco Tanks and Presidio Bolson resource areas were identified by matching postulated temperature characteristics of the geothermal resource to the need cha… more

Finite medium Green's function solutions to nuclide transport in porous media

Description: Current analytical techniques for predicting the transport of nuclides in porous materials center on the Green's function approach - i.e., determining the response characteristics of a geologic pathway to an impulse function input. To data, the analyses all have set the boundary conditions needed to solve the 1-D transport equation as though each pathway were infinite in length. The purpose of this work is to critically examine the effect that this infinite pathway assumption has on Green's fun… more

Atomic reaction rates in H/sup -/ and D/sup -/ plasmas

Description: The processes leading to negative ion production in a hydrogen plasma are reviewed. Dissociative attachment of electrons to highly excited vibrational states of hydrogen molecules appears to be the most probable source of negative ions. The possibility of significant negative ion production via dissociative recombination of H/sub 3//sup +/ with electrons cannot be excluded. The survival probability of vibrationally excited hydrogen molecules in wall collisions may be a critical parameter in int… more

Some features of Rayleigh scattering from light atoms and ions

Description: When photon energies are well below 1 MeV the only significant contribution to elastic (coherent) photon-atom scattering comes from Rayleigh scattering, the elastic scattering of photons from bound atomic electrons. This report discusses the Rayleigh scattering cross sections for atoms and ions of low nuclear charge, particularly for photon energies in the vicinity of the threshold for photoionization from the K-shell. Just below this threshold energy there is a sequence of resonances in the el… more
