Uranium miner lung cancer study. Progress report, July 1, 1975--July 1, 1976

Description: This study on the rate of lung cancer development in uranium miners was initiated in 1957 by the U. S. Public Health and many facets of this project are reaching final objectives. Many new studies have developed in the course of this study and will continue. The projects supported by The Energy Research and Development Administration are of utmost importance and consist of: collection of material from uranium miners known to have cancer of the lung into a tumor registry; manual on pulmonary cyt… more

Scattered light evidence for short density scale heights near critical density in laser-irradiated plasmas

Description: Experimental evidence is presented of a steepened electron density profile near critical density obtained from studying the time-integrated scattered light from targets illuminated by linearly polarized, 1.06 ..mu.. light. Both 10 ..mu.. thick disks and DT-filled glass microshells were irradiated by light focused by f/1 or f/2.5 lenses in one and two-beam experiments, respectively. From the dependence of the asymmetry of the scattered light about the beam axis upon the scattering angle, we infe… more

Silicon ribbon growth by a capillary action shaping technique. Quarterly technical progress report No. 5

Description: MOS C-t measurements were used to characterize lifetime in CAST crystals and its dependency on crystal defects. Four classes of ribbon perfection are defined. These perfection categories are coordinated with lifetime ranges and efficiency ranges of solar cells. Lifetime degrading properties of different defects are qualitatively discussed in terms of ''electrical activity.'' Electrical activity measurements of crystallographic defects in ribbons were made through the SEM EBIC techniques using S… more

Measurement of the widths of emission lines from laser produced plasmas

Description: The targets used for the creation of laser produced plasmas often contain sodium, silicon and other period 3 elements. Temperature and density information can be inferred from detailed study of the characteristic radiation from these elements. The resolution capabilities of crystal spectrographs designed to look at such target radiation are discussed. Data from several types of spectrographs are compared. The fine structure of the hydrogen and helium-like silicon lines are used to illustrate sp… more

Water supply dilemmas of geothermal development in the Imperial Valley of California

Description: There are four known geothermal resource areas in the Imperial Valley that have a combined potential of over 4,000 megawatts of electrical energy for 25 years. The water resources available to support geothermal energy development are imported Colorado River water, agricultural waste waters, Salton Sea water, and ground water. In addition, geothermal power plants can produce their own cooling water in the form of steam condensate. Nevertheless, the relatively high water requirements of geotherm… more

Large area silicon sheet by EFG. Annual progress report, October 29, 1975--September 30, 1976

Description: At the end of one year the program is on schedule. EFG ribbon growth system JPL No. 2 is being used to perform meaningful growth rate and ribbon thickness experiments. The new, wide ribbon growth system is in operation. A theoretical study of stresses in ribbons is reported. EFG ribbons have been observed to exhibit a characteristic defect structure which is orientation dependent in the early stages of growth.

Measurement of high energy ions. [Time-of-flight spectrometer]

Description: The current interest in fast ions has prompted the design of a new time-of-flight ion spectrometer which measures the high energy ions from a laser produced plasma. A magnet was used to separate the ions from the intense background of electrons, x-rays and scattered light. The design of the instrument is wide band so that ions with energies 0.03 to 3000 keV/amu can be measured. Results from target experiments on the LLL ARGUS laser facility will be presented. The fast ion spectrum is dovetailed… more
