Image collapsing concentrators. Interim scientific report No. 2

Description: A cylindrical Fresnel-type lens has been designed and ray traced that focuses approximately to lines over a 60/sup 0/ elevation angle interval. Forty stepped prism facets are configured on the inside surface of the lens, and the lens outer surface can be well approximated by a smooth circular arc. Especially contoured cylindrical subreflectors are described for concentrating the broad image fields of the lens onto a narrow fixed shelf. These image collapsing subreflectors also compensate for fo… more

Beam deflection into a quadrant by a positionally stationary magnetic bending system

Description: A system of postionally stationary magnets is analyzed for the continuously variable deflection of a 50 MeV electron beam. The system is composed of a collection of horizontal and vertical bending magnets, quadrupoles, and a final deflection magnet that is conical in shape and capable of deflections of plus or minus 50 degrees simultaneously in both horizonal and vertical planes. Throughout the system the beam is assumed to be focused by its own magnetic self-field, the electric self-field bein… more

Transmission-line access for hydrothermal target prospects in the five Pacific Rim states: a legal/institutional analysis. Report No. 1022

Description: Transmission line access is discussed as a legal and institutional problem impacting geothermal commercialization. A legal and regulatory overview is presented starting with the Federal Power Act of 1935. The legal and institutional attributes of both Bonneville Power Authority and the California Power Pool as well as their satellite transmission systems are examined, with an eye towards the setting that they, as institutions, will present to geothermal commercialization. The physical realities… more

Reduction of the beam breakup mode Q values in the ETA/ATA Accelerating Cells

Description: Earlier Microwave Measurements of the ETA Accelerating Cells has uncovered eleven resonances in the frequency range of 0 > 850 MHz. The Q values of these modes ranged from 14 to 70. A three phase program directed at substantially reducing these Q values is reported. In particular the dampening methods described below resulted in a decrease of Q value from 40 to 5 for the beam breakup mode (TM/sub 110/) with a corresponding reduction for most of the other cavity modes.

Fundamentals and techniques of nonimaging optics for solar energy concentration. Final report

Description: Nonimaging optics is a new discipline with techniques, formalism and objectives quite distinct from the traditional methods of focusing optics. These new systems achieve or closely approach the maximum concentration permitted by the Second Law of Thermodynamics for a given angular acceptance and are often called ideal. Application of these new principles to solar energy over the past seven years has led to the invention of a new class of solar concentrators, the most well known version of which… more

Environmental assessment for a geothermal direct utilization project in Reno, Nevada

Description: The proposed action involves the development of geothermal wells to provide hot water and heat for five users in Reno, Nevada. Data from nearby wells indicate the sufficient hot water is available from the Moana Known Geothermal Resource Area for this action. Construction activities have been planned to minimize or eliminate problems with noise, runoff, and disturbance of biota as well as other potential environmental effects. Disposal of the geothermal fluids via surface water or injection wil… more

Inspection of irradiated P-7 fuel tubes

Description: Mark 16 U-A1 alloy production fuel tubes and six special U{sub 3}O{sub 8}-A1 powder metallurgy (PM) test assemblies were successfully irradiated in P-7 reactor charge beginning December 1976. A year after irradiation, the outer surfaces were inspected under water in P-Area basin. Inspection showed that a black'' oxide had formed on the bottom {sup {approximately}}2/3 and flaked off in some areas for both the production and PM tubes. A small cladding defect was also observed on one PM outer tube… more
