Electron cyclotron resonance deposition of amorphous silicon alloy films and devices
This report describes work to develop a state-of-the-art electron cyclotron resonance (ECR) plasma-enhanced chemical vapor deposition (PECVD) system. The objective was to understand the deposition processes of amorphous silicon (a-Si:H) and related alloys, with a best-effort improvement of optoelectronic material properties and best-effort stabilization of solar cell performance. ECR growth parameters were systematically and extensively investigated; materials characterization included constant photocurrent measurement (CPM), junction capacitance, drive-level capacitance profiling (DLCP), optical transmission, light and dark photoconductivity, and small-angle X-ray scattering (SAXS). Conventional ECR-deposited a-Si:H was compared to a new form, a-Si:(Xe, H), in which xenon gas was added to the ECR plasma. a-Si:(Xe,H) possessed low, stable dark conductivities and high photosensitivites. Light-soaking revealed photodegradation rates about 35% lower than those of comparable radio frequency (rf)-deposited material. ECR-deposited p-type a SiC:H and intrinsic a-Si:H films underwent evaluation as components of p-i-n solar cells with standard rf films for the remaining layers.

Rehabilitation Potential and Practices of Colorado Oil Shale Lands. Progress Report, June 1, 1976--May 31, 1977
Substantial progress has been made towards implementing all of the prescribed studies and satisfying the stated objectives since the Oil Shale Rehabilitation Project was actively initiated in June 1976. Concurrent with implementation, research objectives were substantively defined and supplemented without distracting or departing from the original purpose. Current studies are designed to fill voids in the present status of knowledge regarding lands disturbed by an impending oil shale industry in Colorado. The efforts of all contributing investigators have therefore been integrated and directed toward the goal of developing methodologies requisite for restoring diverse and complex ecosystems which will require only a minimal amount of maintenance or input of scarce resources. An intensive study site southeast of the Oil Shale Tract C-a has been obtained through a Cooperative Agreement with the Bureau of Land Management. Following this agreement, most subprojects were initiated at the intensive site. Additional programs will be implemented as spent shale becomes available this summer. Studies conducted principally in the laboratory and greenhouse, such as the microbiological and plant genetic studies, have achieved significant results.

Brine chemistry: scaling and corrosion. Geothermal research study in the Salton Sea region of California
The purpose of this report is to recommend a reasonable program of brine chemistry research that will result in the development of methods for predicting and controlling scale deposition, and in guidelines for the selection of corrosion-resistant construction materials. First, background information, which is necessary for the understanding of the problems of scaling and corrosion in the Salton Sea KGRA, is presented through a review of the history of geothermal exploration and development in the Salton Sea. Second, literature relevant to the geochemistry of the Salton Sea field is reviewed and important results are emphasized. Third, current research efforts directed toward actual power plant construction are summarized and evaluated. Fourth, research which has been proposed but is not currently funded is discussed. Fifth, because silica scaling has been the most troublesome problem in the past, the basic chemistry of silica and its relationship to scaling is discussed. Sixth, recommendations for future research are made in which a fundamental engineering approach is emphasized. In this approach, experiments would be conducted on actual process equipment and detailed chemical analyses would be performed on site in well-equipped field laboratories. 88 references.

Fluxes of Tracers in Wind and Water Tunnels
The absorption process of particulate matter at an air-water interface was studied by means of a Monte Carlo Simulation. This absorption process does not appear to be significantly different from similar processes over stationary boundaries. Especially an increased flux toward the boundary as the result of more effective particle removal due to wave action could not be observed. The particular nature of the tracer prevents this from happening.

Low-cost silicon solar array project. First annual report, January 1975--March 1976
The Low-Cost Silicon Solar Array Project (LSSA) was established to greatly reduce the price of solar arrays by the improvement of manufacturing technology, by adaptation of mass production techniques, and by helping achievement of user acceptance. The Project's approach includes the development of technology, its transfer by industry to commercial practice, the evaluation of the economics involved, and the stimulation of market growth. The activities and progress of the LSSA Project during its first year are described in this document which covers all Project activities, with primary emphasis on the technical plans and accomplishments. The development of manufacturing technology is now and will continue to be performed principally by industries and universities. To date, 24 contractors are working on new silicon-refinement processes, silicon-sheet-growth techniques, encapsulants, and automated-assembly studies. Nine more contractors have been selected to perform additional technology investigations and their contracts are being negotiated. Additional contracts will be issued in the future as promising ideas appear. (WDM)

Cost of energy from utility-owned solar electric systems. A required revenue method for ERDA/EPRI evaluations
This methodology calculates the electric energy busbar cost from a utility-owned solar electric system. This approach is applicable to both publicly- and privately-owned utilities. Busbar cost represents the minimum price per unit of energy consistent with producing system-resultant revenues equal to the sum of system-resultant costs. This equality is expressed in present value terms, where the discount rate used reflects the rate of return required on invested capital. Major input variables describe the output capabilities and capital cost of the energy system, the cash flows required for system operation and maintenance, and the financial structure and tax environment of the utility.

Low-Cost Silicon Solar Array Project. Quarterly report 3, October 1976--December 1976
The potential for future widespread use of photovoltaic systems for the generation of electric power was the motivation for the establishment, in January 1975, of the Photovoltaic Conversion Program by ERDA's Division of Solar Energy. The Program's activities are planned to develop and to promote the use of photovoltaic systems to such an extent that the private sector will produce and utilize cost-competitive photovoltaic systems. As part of the ERDA Program, the Low-Cost Silicon Solar Array Project (LSSA) was established in January 1975. The activities and progress of the LSSA Project during the months of October, November, and December 1976 are described. The Project objective is to develop the national capability to produce low-cost, long-life photovoltaic arrays at a rate greater than 500 megawatts per year and a price of less than $500 per kilowatt peak by 1986. The array performance goals include an efficiency greater than 10% and an operating lifetime in excess of 20 years. The approach is to reduce the cost of solar cell arrays by improving solar array manufacturing technology and by increasing solar array production capacity and quantity. Forty-seven contracts have been awarded to date, to industrial firms and university and independent laboratories for experimental …

Steepened magnetosonic waves in the high. beta. plasma surrounding Comet Giacobini-Zinner
We extend the previous studies of intense hydromagnetic waves at Giacobini-Zinner to investigate the mode and direction of wave propagation. Simultaneous high-resolution measurements of electron density fluctuations demonstrate that the long period (approx.100 s) waves are propagating in the magnetosonic mode. Principal axis analyses of the long period waves and accompanying partial rotations show that the sum of the wave phase rotations is 360/sup 0/C, indicating that both are parts of the same wave oscillation. From the time sequence of the steepened waveforms observed by ICE, we demonstrate that the waves must propagate towards the sun with C/sub ph/ < V/sub sw/. All available observations are consistent with wave generation by the resonant ion ring or ion beam instability which predicts right-hand polarized waves propagating in the ion beam (solar) direction. The large amplitudes ..delta.. polarized B/absolute value of Bapprox.0(1) and small scale sizes (rotational discontinuities) of the cometary waves suggest that rapid pitch-angle scattering and energy transfer with energetic ions should occur. Since the waves are highly compressive, ..delta.. absolute value of B/absolute value of B = 0(0.5), one can also anticipate first-order Fermi acceleration. 15 refs., 6 figs.

General Circulation of the Atmosphere and Weather in the Mediterranean
The occurrence of mistral winds in the Mediterranean shows a correlation with blocking activity over the eastern Atlantic. Apparently for this reason periods with a ''midwinter dip'' in the zonal available potential energy of the northern hemisphere are favored by mistral occurrence. There also is a tendency for a 22- to 26-day cycle to appear in pressure gradients at the 500- and 100-mb surfaces along the southern coast of France. Such pressure gradients, if they exceed a certain magnitude, are indicative of mistral episodes.

Evaluation of Aftermarket Fuel Delivery Systems for Natural Gas and Lpg Vehicles
This study was designed to evaluate the effectiveness of aftermarket fuel delivery systems for vehicles fueled by compressed natural gas (CNG) and liquefied petroleum gas (LPG). Most of the CNG and LPG vehicles studied were converted to the alternative fuel after purchase. There are wide variations in the quality of the conversion hardware and the installation. This leads to questions about the overall quality of the converted vehicles, in terms of emissions, safety, and performance. There is a considerable body of emissions data for converted light-duty vehicles, and a smaller amount for medium- and heavy-duty vehicles. However, very few of these data involve real world conditions, and there is growing concern about in-use emissions. This report also attempts to assess factors that could allow in-use emissions to vary from the best-case'' results normally reported. The study also addresses issues of fuel supply, fuel composition, performance, safety, and warranty waivers. The report is based on an extensive literature and product survey and on the author's experience with fuel delivery systems for light-duty vehicles.

Geochemical reconnaissance for uranium in the arid regions of the western United States
In developing the sampling strategy for the seven western states, the Lawrence Livermore Laboratory (LLL) divided the region into geologic and physiographic provinces. A large part of the LLL region of responsibility lies within the arid to semi-arid Basin and Range province. This region is characterized as an area of rather complex geology with internal drainage. The desert-like conditions in many parts of this region result in a unique set of problems which requires a unique reconnaissance program. In this paper, I will describe some of the features of the LLL program which are keyed to the desert environment in the northern Basin and Range province.

Nuclear Physics Laboratory, University of Colorado Technical Progress Report, 1976 and Proposal for Continuation of Contract
This report summarizes the work carried out at the Nuclear Physics Laboratory of the University of Colorado during the period November 1, 1975 to November 1, 1976. The low energy nuclear physics section is dominated by light-ion reaction studies which span a wide range. These include both two-neutron and two-proton transfer reactions, charge exchange and inelastic scattering, as well as single nucleon transfer reactions. The nuclei studied vary widely in their mass and characteristics. These reaction studies have been aided by the multi-use scattering chamber which now allows the energy-loss-spectrometer beam preparation system (beam swinger) to shift from charged particle studies to neutron time-of-flight studies with a minimum loss of time. The intermediate energy section reflects the increase in activity accompanying the arrival of LAMPF data and the initiation of (p,d) studies at the Indiana separated-sector cyclotron. The nucleon removal results provided by the ..pi.. beam at EPICS previous to completion of the spectrometer have shown that nuclear effects dominate this process, so that the widely used free interaction picture is inadequate. The section entitled ''Other Activities'' reveals continuing activities in new applications of nuclear techniques to problems in medicine and biology. Reactions important to astrophysics continue to be investigated …
