E-740 proportional drift tube tests

Description: The D0 muton detector will consist of large area arrays of proportional drift tubes (PDT's). The beam crossing repetition rate together with the trigger processing time will constrain the maximum drift time to be about one microsecond, corresponding to a drift distance of about 5.0 cm. With such a narrow cell width, it is possible to use rather long cells (up to 6.0 meters) and still keep cell occupancy acceptable. To simplify track reconstruction, space points will be recorded for each track. … more

Analysis of anions in geological brines using ion chromatography

Description: Ion chromatographic procedures for the determination of the anions bromide, sulfate, nitrite, nitrate, phosphate, and iodide in brine samples have been developed and are described. The techniques have been applied to the analysis of natural brines, and geologic evaporites. Sample matrices varied over a range from 15,000 mg/L to 200,000 mg/L total halogens, nearly all of which is chloride. The analyzed anion concentrations ranged from less than 5 mg/L in the cases of nitrite, nitrate, and phosph… more

Analysis of nonisothermal injection and falloff tests in layered reservoirs

Description: The effects of reservoir layering and gravity segregation on nonisothermal injection and falloff tests are investigated. Results show that layering does not affect injection or falloff data if all the layers are permeable and accept fluids from the wellbore. In such cases, the average permeability, skin factor, and distance to the thermal front can be calculated using the techniques developed for homogeneous reservoirs. Special considerations have to be taken for cases where several layers are … more

Analysis of sediments and soils for chemical contamination for the design of US Navy homeport facility at East Waterway of Everett Harbor, Washington. Final report. [Macoma inquinata; Mytilus edulis]

Description: Contaminated sediments in the East Waterway of Everett Harbor, Washington, are extremely localized; they consist of a layer of organically-rich, fine sediments overlying a relatively cleaner, more sandy native material. The contaminated layer varies in thickness throughout the waterway from as much as 2 meters to only a few centimeters. Generally, the layer is thicker and more contaminated at the head of the waterway (northern end) and becomes thinner and less contaminated as one proceeds south… more

Angle-resolved photoemission extended fine structure

Description: Measurements of the Angle-Resolved Photoemission Extended Fine Structure (ARPEFS) from the S(1s) core level of a c(2 x 2)S/Ni(001) are analyzed to determine the spacing between the S overlayer and the first and second Ni layers. ARPEFS is a type of photoelectron diffraction measurement in which the photoelectron kinetic energy is swept typically from 100 to 600 eV. By using this wide range of intermediate energies we add high precision and theoretical simplification to the advantages of the pho… more

Angular distribution of neutral hydrogen following collisional electron detachment from H/sup -/

Description: The angular distribution of neutral hydrogen following electron detachment from H/sup -/ has been measured for H/sup -/ on nitrogen and hydrogen gas, both for neutral atoms left in the 2S state, and for all neutrals independent of the state of excitation. The results are essentially in agreement with calculations based on the Born approximation, although there is some disagreement in detail.

Annual environmental monitoring report, January-December 1984

Description: Non-radioactive monitoring program involved: repair of a leaking waste paint and solvent tank, installation of a pretreatment facility for liquid effluents from a plating shop; and construction discharge. Radioactivity was monitored for air with comparisons to the average annual population dose from neutron radiation and tritium in the waste water effluents.

Aperture study

Description: A simple computer study was done to compare the effect of an aperture reduction from 5 cm to 4 cm on the cable conductor requirements. Two extreme cases were considered; first the same cable, and second, the cable width was changed to be the same radial percentage of the aperture. The current density was then adjusted to produce the same central field. The field quality was computed at 2/3 aperture.

Applications of decelerated ions

Description: Many facilities whose sole purpose had been to accelerate ion beams are now becoming decelerators as well. The development and current status of accel-decel operations is reviewed here. Applications of decelerated ions in atomic physics experiments are discussed.

Asymptotic analysis of rf-heated collisional plasma

Description: It is shown that a distribution of electrons in resonance with traveling waves, but colliding with background distributions of electrons and ions, evolves to a steady state. Details of the steady state are given analytically in the asymptotic limit of high electron energy and are compared with numerical solutions. The asymptotic analytic solution may be useful for quickly relating emission data to likely excitations and is more reliable than conventional numerical solutions at high energy. A me… more

Atomic mechanisms of. gamma. ' precipitate plate growth in the Al-Ag system

Description: Energy-dispersive x-ray spectroscopy results that the precipitates have the composition Ag/sub 2/Al. High-resolution electron microscopy of ..gamma..' precipitates in both <110>//<1120> and <111>//<0001> orientations shows that all interfaces of the precipitate are largely coherent with the matrix and are faceted along low-energy (111) and (110) matrix plans, due to the influence of surface and elastic strain energies on the transformation. Further comparison between experimental and calculated… more

CAMAC 488 module: 68,000 based GPIB interface module

Description: What kind of hardware and software should be used to interface GPIB devices with the existing computer system. One idea was to use a commercially available Multibus card, BLC 8488 from National Semiconductor, whose on-board Z80 would manage the GPIB read/write functions and handshakes. With this card, one could make a hardware system which would consist of (1) CAMAC 080, (2) Multibus crate, (3) M. Shea's M68000, (4) M080, (5) BLC 8488 and (6) memory board. And the software considered for such a… more

Categorization of nocturnal drainage flows within the Brush Creek valley in western Colorado and the variability of sigma theta in complex terrain

Description: The monthly frequencies of nocturnal drainage flows in the Brush Creek valley were estimated over the period August 1982 to January 1985 for the purpose of evaluating the representativeness of the drainage flows observed during a few intensive study periods. These estimates were made on the basis of data from three short meteorological towers situated in the valley. The highest frequencies were observed during the June to October timeframes: 30 to 40% during 1983 and 10 to 30% during 1984. Of t… more

Characteristics of microearthquakes accompanying hydraulic fracturing as determined from studies of spectra of seismic waveforms

Description: A study of the spectral properties of the waveforms recorded during hydraulic fracturing earthquakes has been carried out to obtain information about the physical dimensions of the earthquakes. We find two types of events. The first type has waveforms with clear P and S arrivals and spectra that are very similar to earthquakes occurring in tectonic regions. These events are interpreted as being due to shear slip along fault planes. The second type of event has waveforms that are similar in many… more
