Access control system for ISABELLE

An access system based on the one now in operation at the CERN ISR is recommended. Access doors would presumably be located at the entrances to the utility tunnels connecting the support buildings with the ring. Persons requesting access would insert an identity card into a scanner to activate the system. The request would be autologged, the keybank adjacent to the door would be unlocked and ISABELLE operations would be notified. The operator would then select the door, activating a TV-audio link. The person requesting entry would draw a key from the bank, show it and his film badge to the operator who would enable the door release.

Auger study of surface carbon and oxygen on thorium following ion bombardment

The composition of a thorium metal surface has been monitored using Auger electron spectroscopy following Ar/sup +/ bombardment at different temperatures. After extended Ar/sup +/ bombardment, enough contaminated overlayers were removed to expose a surface region containing only thorium, bulk impurities, and imbedded argon. The main impurities, carbon and oxygen, differed in their behavior when the sample was annealed following bombardment. The amount of surface carbon either increased or remained constant during annealing depending upon the temperature of the sample during bombardment. The amount of surface oxygen decreased rapidly when the sample was heated above 500/sup 0/C regardless of the sample temperature during bombardment. These experiments indicate that preparation of clean, annealed thorium surfaces requires ion bombardment at temperatures > or = 400/sup 0/C.

Program manual for the Data Director editor

The Data Director editor is a powerful, multiuser editor that will aid in the development and modification of APT part programs, assembly-language programs, and other text. Some benefits of the editor are as follows: most of the editor is reentrant, allowing several users to share it; the user can use the editor as though the entire file being edited is in memory; editing takes place on a working file so that changes are not made to the original file until desired; the editor offers a powerful command set where most commands have the same syntax. 1 table.

Stimulated Raman scatter in laser fusion target chambers

The target chamber of a laser fusion reactor will contain small amounts of background gases. As the beam is focused, it ionizes the gas and Raman scattering is induced. Density limits on the background gas are found in order that the laser beam will not become appreciably decollimated. It is found that laser bandwidth efficiently decreases the scattering effect.

Methodology for assessing the potential impact on air quality resulting from geothermal resource development in the Imperial Valley

Methodology in use in the Imperial Valley for assessing the potential impact on air quality that may result from the development of geothermal resources is discussed. The installation of a network of air quality stations for characterizing the air quality and atmospheric transport properties in the valley prior to development is discussed. Analyses of geothermal fluids for various gases are performed to evaluate the potential emission rates from future geothermal power plants. The principal pollutant of concern is H/sub 2/S because of its noxious odor and potential release rate. These estimated source emission rates and the appropriate meteorological measurements are used as input to a three-dimensional, atmospheric transport code to estimate the potential changes in air quality that result from various scenarios for development of geothermal power.

Mechanical design for TMX injector system

The injector system for the Tandem Mirror Experiment (TMX) contains the components required to create and maintain a high-temperature, high-density plasma. These components include a streaming-plasma gun in each of the plug tanks to form the target-plasma, 24 neutral-beam source modules for injecting neutral deuterium atoms to heat and replace losses from the plasma, and a gas box system that applies a streaming cold gas to the plasma to stabilize it. This paper discusses the mechanical design problems and solutions for this injector system.

Liquid nitrogen cooled liners for 2XIIB

Liquid-nitrogen-cooled liners have been installed in the neutral-beam source tanks of 2XIIB. The installation has resulted in improvements in vacuum pumping, although testing is not complete. The liners are stainless-steel-flooded-type liners, using spot-welded-and-inflation construction. The natural-convection flow system must keep the liners cold during the high heat loads imposed during Ti gettering.

Comparison of theory and simulations with recent laser plasma experiments

In the past few months, detailed experimental data have become available on laser light absorption versus angle, plasma density profiles near the critical surface, and stimulated scattering processes. In the light of these experiments, it seems timely to reassess our theoretical understanding of these phenomena. A quantitative comparison of the data with current results of plasma simulations and theory is presented and the areas where further theoretical effort is called for are pointed out. Three recent experiments done at Livermore are compared with the latest theoretical and simulation results on laser-plasma interactions. The analysis covers the following areas: (1) theory of resonance absorption on a rippled critical surface, compared with an experiment on the angle and polarization dependence of absorption; (2) theory of density profile steepening, compared with holographic interferometry measurements; and (3) theory of stimulated Brillouin scattering in long density gradients, compared with reflectivity measurements for long pulse, large focal spot experiments.

Geothermal Loan Guaranty Program

Presently the US imports a large proportion of its petroleum requirements. This dependence on foreign petroleum has had a major impact on our economy. As a result, the Federal government is sponsoring programs to offset this foreign reliance by conservation of oil and gas, conversion of petroleum using facilities to coal and nuclear energy and the development of alternate sources of energy. One of the most acceptable alternate resources is geothermal. It offers an environmentally sound energy resource, can be developed at reasonable cost in comparison to other forms of energy and has a long term production capacity. On September 3, 1974, the Geothermal Energy Research Development and Demonstration Act was enacted to further the research, development and demonstration of geothermal energy technologies. This Act also established the Geothermal Loan Guaranty Program to assist in the financing of geothermal resource development, both electrical and non-electrical. The highlights of that Guaranty Program are detailed in this report.
