100 Areas technical activities report -- Physics, November 1946
This report divides the activities for November into three sections: D Pile; F Pile; and general physics. During November the D Pile was down twice for regularly scheduled shutdowns. Two scram occurred during the month, both of short duration. Five Special Request 15 tubes were discharged and recharged with Special Request 15. Some 13 inhour of reactivity were gained during the month. Vertical rod thimbles, 10 through 22, were tested. A Production Test was performed to determine the reactivity power coefficients of the F Pile at low power levels and with practically no xenon poison remaining. Additional experience in the use of temporary poison columns during an extended shutdown of the pile was obtained during the month. Four new bismuth columns were charged during the month and six tubes were charged with LiF. The F Pile had not yet returned to xenon equilibrium following the shutdown of November 27 at the end of the month, but conditions just prior to this shutdown indicate a loss of one inhour since October 31. Two sets of specimens were removed from the ``B`` Test Hole of the F Pile on November 4. Samples were also machined from graphite removed from the No. 9 …

Active voltammetric microsensors with neural signal processing.
Many industrial and environmental processes, including bioremediation, would benefit from the feedback and control information provided by a local multi-analyte chemical sensor. For most processes, such a sensor would need to be rugged enough to be placed in situ for long-term remote monitoring, and inexpensive enough to be fielded in useful numbers. The multi-analyte capability is difficult to obtain from common passive sensors, but can be provided by an active device that produces a spectrum-type response. Such new active gas microsensor technology has been developed at Argonne National Laboratory. The technology couples an electrocatalytic ceramic-metallic (cermet) microsensor with a voltammetric measurement technique and advanced neural signal processing. It has been demonstrated to be flexible, rugged, and very economical to produce and deploy. Both narrow interest detectors and wide spectrum instruments have been developed around this technology. Much of this technology's strength lies in the active measurement technique employed. The technique involves applying voltammetry to a miniature electrocatalytic cell to produce unique chemical ''signatures'' from the analytes. These signatures are processed with neural pattern recognition algorithms to identify and quantify the components in the analyte. The neural signal processing allows for innovative sampling and analysis strategies to be employed with the …

Aerogel derived catalysts
Aerogels area class of colloidal materials which have high surface areas and abundant mesoporous structure. SiO{sub 2} aerogels show unique physical, optical and structural properties. When catalytic metals are incorporated in the aerogel framework, the potential exists for new and very effective catalysts for industrial processes. Three applications of these metal-containing SiO{sub 2} aerogels as catalysts are briefly reviewed in this paper--NO{sub x} reduction, volatile organic compound destruction, and partial oxidation of methane.

An Analysis of Shot Noise Propagation and Amplificationin Harmonic Cascade FELs
The harmonic generation process in a harmonic cascade (HC) FEL is subject to noise degradation which is proportional to the square of the total harmonic order. In this paper, we study the shot noise evolution in the first-stage modulator and radiator of a HC FEL that produces the dominant noise contributions. We derive the effective input noise for a modulator operating in the low-gain regime, and analyze the radiator noise for a density-modulated beam. The significance of these noise sources in different harmonic cascade designs is also discussed.

Application of Reservoir Characterization and Advanced Technology to Improve Recovery and Economics in a Lower Quality Shallow Shelf San Andres Reservoir. Quarterly Progress Report: July 1--September 30, 2001
The Class 2 Project at West Welch was designed to demonstrate the use of advanced technologies to enhance the economics of improved oil recovery (IOR) projects in lower quality Shallow Shelf Carbonate (SSC) reservoirs, resulting in recovery of additional oil that would otherwise be left in the reservoir at project abandonment. Accurate reservoir description is critical to the effective evaluation and efficient design of IOR projects in the heterogeneous SSC reservoirs. Therefore, the majority of Budget Period 1 was devoted to reservoir characterization. Technologies being demonstrated include: (1) Advanced petrophysics; (2) Three-dimensional (3-D) seismic; (3) Crosswell bore tomography; (4) Advanced reservoir simulation; (5) Carbon dioxide (CO{sub 2}) stimulation treatments; (6) Hydraulic fracturing design and monitoring; and (7) Mobility control agents.

Application of the mercury-catalyzed aluminum jacket dissolving technique to the Redox process
The possible means of removing aluminum jackets from uranium slugs were considered before Hanford start-up in 1944, and have been considered at other sites for processing other types of slugs. The sodium hydroxide-sodium nitrate dissolution, which served well for Bismuth Phosphate plant operation was accepted for use in the Redox plant. The other means of jacket removal, namely, dissolving the jacket in nitric acid with the aid of mercury as a catalyst, has been adapted for use at Arco and offers certain possible advantages for Redox Plant operation. The primary purpose of this document is three-fold: To report exploratory experimental work performed to date in the Process Chemistry laboratories on the study of the dissolving reaction and the properties of the resultant feed solution; to present a summary of the status of related work at other sites and by other groups at the site, as determined from a survey of the available literature references; to outline questions yet to be answered before the process may be used in the Redox Plant and a program to be followed to answer these questions.

Authorization for use of an alternate method of processing turnings: 234-5 Building, briquetting of plutonium turnings
Plutonium turnings formed in the machining operation are processed by recycling them to the reduction operation. The turnings are here combined in the radiation charge to form a button with the plutonium from the reduction of the fluoride. Occasionally an inventory of turning will accumulate, especially when a number of machined pieces are recycled to be recast. Since the amount of turnings to plutonium in plutonium fluoride considered safe for reduction is a maximum ratio of 1.35, a high turnings inventory can only be expended at a limited rate. Briquetting offers a convenient way of depleting the turnings inventory in a rapid manner. A total of twenty-four briquettes were pressed. Eight castings were made by casting three briquettes into a form suitable for further processing. Six of the eight castings were accepted at final inspection. One was too small to machine due to an interrupted heating cycle and the other was recast after two coating failures with subsequent stripping caused the piece to be out of specifications in size. Castings made from briquettes were comparable with those made from buttons in parity, homogeneity of the alloy, and lack of voids. Skulls from the casting of briquettes varied form 10 to …

Beauty, charm and hyperon production at fixed-target experiments
Over the years fixed-target experiments have performed numerous studies of particle production in strong interactions. The experiments have been performed with different types of beam particles of varying energies, and many different target materials. Since the physics of particle production is still not understood, ongoing research of phenomena that we observe as beauty, charm and strange-particle production is crucial if we are to gain an understanding of these fundamental processes. It is in this context that recent results from fixed-target experiments on beauty, charm, and hyperon production will be reviewed.

Biodegradation of Chlorinated Solvents: Reactions near DNAPL and Enzyme Function
Chlorinated solvents are among the most widespread groundwater contaminants in the country, contamination which is also among the most difficult and expensive for remediation. These solvents are biodegradable in the absence of oxygen, but this biodegradation requires both a food source for the organisms (electron donor) and the presence of chlorinated solvent biodegrading organisms. These two requirements are present naturally at some contamination sites, leading to natural attenuation of the solvents. If one or both requirements are absent, then engineered bioremediation either through addition of an external electron donor or through bioaugmentation with appropriate microorganisms, or both, may be used for site remediation. The most difficult case for cleanup is when a large residual of undissolved chlorinated solvents are present, residing as dense -non-aqueous-phase- liquid ( DNAPL). A major focus of this study was on the potential for biodegradation of the solvents when pre sent as DNAPL where concentrations are very high and potential for toxicity to microorganisms exist. Another focus was on a better understanding of the biological mechanisms involved in chlorinated solvent biodegradation . These studies were directed towards the chlorinated solvents, trichloroethene (TCE), tetrachloroethene or perchloroethene (PCE), and carbon tetrachloride (CT). The potential for biodegradation of TCE …

Bulk metallic glass formation in the Pd-Ni-P and Pd-Cu-P alloy systems
Bulk metallic glasses were prepared in the Pd-Ni-P and Pd-Cu-P systems using a fluxing technique. The formation of bulk amorphous Pd-Cu-P alloys was reported here for the first time. For both alloy systems, bulk glass formation requires maintaining the phosphorus content near 20 at.%. In the Pd-Ni-P system, 10-mm diameter amorphous Pd{sub x}Ni{sub 80{minus}x}P{sub 20} rods can be formed for 25 {le} x {le} 60. In the Pd-Cu-P system, 7-mm diameter amorphous Pd{sub x}Cu{sub 80{minus}x}P{sub 20} rods can be produced for 40 {le} x {le} 60. From all the ternary alloys studied, Pd{sub 40}Ni{sub 40}P{sub 20} has the highest glass formability, and 25-mm diameter amorphous cylinders, 50 mm in length, can be easily fabricated. The glass stability of the Pd-Ni-P system is wider than that of the Pd-Cu-P system. For most bulk Pd-Ni-P glasses, {Delta}T > 90 K. The {Delta}T values of bulk amorphous Pd-Cu-P alloys are considerably smaller, ranging from 27 to 73 K. The elastic constants of bulk amorphous Pd-Ni-P and Pd-Cu-P alloys were determined using a resonant ultrasound spectroscopy technique. The Pd-Ni-P glasses are slightly stiffer than the Pd-Cu-P glasses. Within each alloy system, the Young`s modulus and the bulk modulus show little change with alloy composition. …
