Design and Testing of a High-Heat Flux Electron-Bombardment Heater

Report issued by the Argonne National Laboratory discussing the testing of an electron-bombardment heater. As stated in the abstract, "the applications of electron-bombardment heating to liquid-metal heat transfer and reactor safety experiments are discussed. The design of a high-heat-flux, electron-bombardment heater (EBH) is presented" (p. 7). This report includes tables, illustrations, and photographs.

Oscillator Strengths and Transition Probabilities fro 3288 Lines of Fe I (open access)

Oscillator Strengths and Transition Probabilities fro 3288 Lines of Fe I

Report of a homogeneous set of intensity-related data calculated for 3288 spectral lines of Fe I in the region from 2100 to 9900 angstroms. The quantities tabulated in the present monograph include log (g__), log (gf), gf,f,gA, and A. Since recent investigations do not support excitations corrections in the case of Fe I and certain other spectra, the present tabulation incorporates a removal of that normalization function. This recalculation affects the values for all lines whose upper energy levels lie above 46000 cm -1 and should significantly improve the internal consistency of the present data.

Playa Surface Morphology: Miscellaneous Investigations (open access)

Playa Surface Morphology: Miscellaneous Investigations

Abstract: Numerous environmental processes affect the development and stability of playa (lakebed) surfaces. Of special significance are hydrologic processes that control the amount and flow of both surface and ground water, and climatic variations which in turn influence the hydrology. This report, in six parts, examines some aspects of the playa surface environment. Chapter 1 is an introduction. Chapter 2 describes microrelief changes that developed at Harper Playa, California, following flooding of the playa in 1965-66. Chapter 3 documents a subsurface hydrologic investigation at Rogers Playa, California. The investigation revealed that the piezometric surface has lowered into sand layers beneath the surface, and it may explain why giant desiccation fissures have formed in the surface clays. Chapter 4 describes an investigation of seven Australian playas and suggests that Australia did not undergo a pluvial period like that of the western United States. Chapter 5 describes three kavirs (playas) in northern Iran and indicates that former lakes did exist there, but not to the same extent as in the western United States. Chapter 6 examines the possibilities of observing playa surface changes from satellites, using the present remote sensor technology. It also states that Gemini color photography and high resolution vidicon …

Trafficability of Soils: Eighteenth Supplement, Development of Revised Mobility Index Formula for Self-Propelled Wheeled Vehicles in Fine-Grained Soils

The main purposes of this study were to (a) obtain adequate test data to determine experimentally the vehicle cone index (VCI) for 50 passes for vehicles mounted with nonconventional tires and (b) use results of the field tests to develop a revised mobility index (MI) formula for self-propelled wheeled vehicles.

An Ultrasonic System for Testing Isotope Heat Capsules (open access)

An Ultrasonic System for Testing Isotope Heat Capsules

Introduction: This report describes a program to develop a nondestructive (ultrasonic) tester and testing procedure to perform integrity tests on isotope heat source containers. The increased application of isotope heat sources has brought more attention to the engineering problems encountered during fabrication. One of the most important of these problems is insuring the isotope containment during the long unattended periods of use. To determine the integrity of the heat source container, a nondestructive testing procedure must be adopted to test each heat source after fabrication.
