Multimode-diode-pumped gas (alkali-vapor) laser

Description: We report the first demonstration of a multimode-diode-pumped gas laser--Rb vapor operating on the 795 nm resonance transition. Peak output of {approx}1 Watt was obtained using a volume-Bragg-grating stabilized pump diode array. The laser's output radiance exceeded the pump radiance by a factor greater than 2000. Power scaling (by pumping with larger diode arrays) is therefore possible.

The Use of Windmills in Irrigation in the Semiarid West

Description: "Within the semiarid region there are millions of acres of rich, fertile land, now barren, some of which will be reclaimed through irrigation, but most of which can not be irrigated on account of the limited water supply, and must be farmed, if at all, without irrigation.... This land is now attracting eastern farmers who are prone to risk failure in view of the possibilities in years of favorable precipitation. There have been many deplorable failures during the recent years which could have been averted had the unfortunate settlers fortified themselves against periods of drought by irrigating small parts of their land holdings. It is realized that to accomplish this requires an outlay of capital and if this outlay is great it precludes the possibility of such procedure. With a view to helping these settlers, this Office has investigated the use of windmills as a means of pumping water for the irrigation of small areas in connection with the farming of more extensive areas without irrigation. It is the purpose of this bulletin to set forth in a simple, comprehensive way the possibilities of irrigation, using windmills only as means of power." -- p. 5

Investigation of Waikele Well No. 2401-01, Oahu, Hawaii: Pumping Test, Well Logs and Water Quality

Description: Introduction: A dependable water supply is required for Naval Magazine Lualualei, Waikele Branch. The water supply for Naval Magazine Lualualei, Waikele Branch, Oahu, Hawaii has been dependent on Oahu Sugar Co.'s water for many years. Because the supply of water from Oahu Sugar Co. is not always dependable, in March 1982, the Pacific Division of the Naval Facilities Engineering Command entered into a cooperative agreement with the U.S. Geological Survey to determine the productivity and water quality of an abandonment Navy well. The well, No. 2401-01, is located in Waikele Gulch near the confluence of Waikele and Kipapa Streams (fig. 1.0-1)

The Use of Windmills in Irrigation in the Semiarid West

Description: "Irrigation has reclaimed many and will reclaim more of the millions of acres of rich, fertile lands of the semiarid region that now are unproductive. Most of this land, however, cannot be irrigated because of the small supply of water, and farming, if done at all, must be without irrigation. True, the farming has been made less hazardous by the growing of drought-resistant crops and the application of improved methods, but success always is threatened by more or less frequent periods of drought. Many failures could have been averted if the farmers from the East who had settled in these regions had provided against such droughts by irrigating small parts of their holdings. This bulletin is intended to aid the farmers by setting out in a simple and comprehensive way the possibilities of the windmill in irrigating small areas in connection with larger tracts farmed without irrigation." -- p. 2

Recent advances in ultraviolet laser technology

Description: The science and technology of violet and ultraviolet lasers has matured rapidly in the last five years. High average power lasers have been demonstrated and several commercial product lines are now available. Single pulse devices have successfully demonstrated large output energies in well controlled beams. In this presentation we will review some of the current laser development programs in progress at Los Alamos. We will describe research in both discharge pumped lasers and E-beam pumped lasers and we will review methods of wavelength conversion in these devices. Finally we will discuss the current understanding of laser induced damage to optical components in the uv.

A NORMETEX MODEL 15 M3/HR WATER VAPOR PUMPING TEST

Description: Tests were performed using a Model 15 m{sup 3}/hr Normetex vacuum pump to determine if pump performance degraded after pumping a humid gas stream. An air feed stream containing 30% water vapor was introduced into the pump for 365 hours with the outlet pressure of the pump near the condensation conditions of the water. Performance of the pump was tested before and after the water vapor pumping test and indicated no loss in performance of the pump. The pump also appeared to tolerate small amounts of condensed water of short duration without increased noise, vibration, or other adverse indications. The Normetex pump was backed by a dual-head diaphragm pump which was affected by the condensation of water and produced some drift in operating conditions during the test.

A Semi-Analytical Solution for Large-Scale Injection-Induced PressurePerturbation and Leakage in a Laterally Bounded Aquifer-AquitardSystem

Description: A number of (semi-)analytical solutions are available to drawdown analysis and leakage estimation of shallow aquifer-aquitard systems. These solutions assume that the systems are laterally infinite. When a large-scale pumping from (or injection into) an aquifer-aquitard system of lower specific storativity occurs, induced pressure perturbation (or hydraulic head drawdown/rise) may reach the lateral boundary of the aquifer. We developed semi-analytical solutions to address the induced pressure perturbation and vertical leakage in a 'laterally bounded' system consisting of an aquifer and an overlying/underlying aquitard. A one-dimensional radial flow equation for the aquifer was coupled with a one-dimensional vertical flow equation for the aquitard, with a no-flow condition imposed on the outer radial boundary. Analytical solutions were obtained for (1) the Laplace-transform hydraulic head drawdown/rise in the aquifer and in the aquitard, (2) the Laplace-transform rate and volume of leakage through the aquifer-aquitard interface integrated up to an arbitrary radial distance, (3) the transformed total leakage rate and volume for the entire interface, and (4) the transformed horizontal flux at any radius. The total leakage rate and volume depend only on the hydrogeologic properties and thicknesses of the aquifer and aquitard, as well as the duration of pumping or injection. It was proven that the total leakage rate and volume are independent of the aquifer's radial extent and wellbore radius. The derived analytical solutions for bounded systems are the generalized solutions of infinite systems. Laplace-transform solutions were numerically inverted to obtain the hydraulic head drawdown/rise, leakage rate, leakage volume, and horizontal flux for given hydrogeologic and geometric conditions of the aquifer-aquitard system, as well as injection/pumping scenarios. Application to a large-scale injection-and-storage problem in a bounded system was demonstrated.

Fast pressure measurements of the local island divertor on the compact helical system

Description: Development of an effective divertor is critical for the viability of the stellarator (helical system) concept. In the local island divertor (LID) concept particle and heat fluxes are channeled to the back of the LID head by the magnetic field structure of an externally produced m = 1, n = I island that is outside the last closed flux surface. The leading edge of the LID head is protected from the outward heat flux from the plasma because it is located inside the 1/1 island and the particles that strike the target plates on the back of the LID head in the throat of the LID pump module are then pumped efficiently. A set of 16 coils was used to create a 1/1 island in the Compact Helical System (CHS). The current (I{sub LID}) in the LID coils was chosen to position either the 0-point or the X-point of the external 1/1 magnetic island at the location of the LID head. The principal diagnostic in this study was an ASDEX-style ionization gauge that allowed fast ({approx}1-ms) measurements of the neutral pressure buildup behind the divertor head in the LID module.

The Effects of Temperature and Carbon Tetrachloride on Polymer Based Hydrogen Getters

Description: This report summarizes hydrogen pumping by organic getters in the presence of carbon tetrachloride, and how the reduction of pumping in the presence of this catalyst poison can be minimized through the choice of catalyst. Catalyst A is shown to be preferred in a clean environment, and catalyst B for a poisoned environment. Additional, we examine the effects of temperature on pumping rates, and show that this getter is effective over a large temperature range from -23 to 107 degrees Celsius.

Evaluating Transmissivity Estimates from Well Hydrographs in Karst Aquifers

Description: Hydrograph recessions from rainfall events have previously been analyzed for discharge at springs and streams; however, relatively little quantitative research has been conducted with regard to hydrograph analysis of recessions from monitoring wells screened in karst aquifers. In previous work a quantitative hydrography analysis technique has been proposed born which matrix transmissivity (i.e., transmissivity of intergranular porosity) and specific yields of matrix, fracture, and conduit components of the aquifer may be determined from well hydrography. The technique has yielded realistic results at three sites tested by the authors thus far (Y-12, Oak Ridge, TN; Crane, IN, and Ft. Campbell, KY). Observed field data, as well as theoretical considerations, show that karst well hydrography are valid indicators of hydraulic properties of the associated karst aquifers. Results show matrix transmissivity (T) values to be in good agreement with values calculated using more traditional parameter estimation techniques such as aquifer pumping tests and slug tests in matrix dominated wells. While the hydrograph analysis technique shows promise for obtaining reliable estimates of karst aquifer T with a simple, relatively inexpensive and passive method, the utility of the technique is limited in its application depending on site-specific hydrologic conditions, which include shallow, submerged conduit systems located in areas with sufficient rainfall for water levels to respond to precipitation events.
