Resonators for heavily beam-loaded linacs

Description: Capacitively loaded resonant line section accelerating structures are discussed. Prototype models were measured at low levels, and calculations were made to predict high level operation. High current composite beams of multiple-beamlets as accelerated by a MEQALAC were assumed.

Management options for implementing a basic and applied research program responsive to CS technology base needs. Task VIII. Review existing CS materials R and D programs

Description: Possibilities for setting up a basic and applied research program that would be responsive to the Conservation and Solar energy base needs are considered with emphasis on the area of materials research. Several organizational arrangements for the implementation of this basic and applied research program are described and analyzed. The key functions of the system such as resources allocation, and program coordination and management follow from two fundamental characteristics: assignment of lead … more

Study to optimize Cr-Mo steels to resist hydrogen and temper embrittlement. Quarterly report No. 6, November 15, 1979-February 15, 1980

Description: A modified test technique has been developed in this program to overcome difficulties in assessing the hydrogen embrittlement susceptibility of low strength 2 1/4 Cr-1 Mo steels. One steel sample was tempered to a range of strength levels and evaluated using the new technique. The results, showing a lower strength level for which hydrogen embrittlement susceptibility can be assessed in a 446 KPa H/sub 2/S environment, are presented in this report. A review of the restructuring of the program is… more

Investigation of sodium carbonate, sodium bicarbonate and water systems for saturated solar ponds. Final report

Description: The overall objective of this study was to gather relevant data primarily from the published literature to investigate the technical feasibility of using a Na/sub 2/CO/sub 3/-NaHCO/sub 3/ mixture for a saturated solar pond. This objective was accomplished by a literature search and review of existing chemical information and by performing simple chemistry experiments in the laboratory. Information on density, solubility, phase diagram, equilibrium compositions, reaction rate constant, equilibri… more

Estimation of neutral-beam-induced field reversal in MFTF by an approximate scaling law

Description: Scaling rules are derived for field-reversed plasmas whose dimensions are common multiples of the ion gyroradius in the vacuum field. These rules are then applied to the tandem MFTF configuration, and it is shown that field reversal appears to be possible for neutral beam currents of the order of 150 amperes, provided that the electron temperature is at least 500 eV.

Cadmium sulfide/copper sulfide heterojunction cell research. Quarterly technical progress report, October 1-December 31, 1979

Description: Extensive modifications to the multi-source reactive sputtering deposition apparatus, including the installation of a larger vacuum chamber on the existing pumping system, have been completed. The new chamber provides improved inter-source shielding, an improved substrate mounting and heating system, and a vacuum interlock for introducing substrates. The investigation of CdS resistivity control by In doping has been continued. It has been established that the resistivity of CdS coatings deposit… more

Design, construction and evaluation of a simulated geothermal flow system

Description: A system was designed and built to simulate the flow from a geothermal well. The simulated flow will be used to power a Lysholm engine, the performance of which will then be evaluated for different simulated geothermal flows. Two main subjects are covered: 1) the design, construction and evaluation of the behavior of the system that simulates the geothermal flow; included in that topic is a discussion of the probable behavior of the Lysholm engine when it is put into operation, and 2) the inves… more

Contract WEC 3. 2. 3 study to optimize Cr-Mo steels to resist hydrogen and temper embrittlement. Quarterly report No. 8, May 15-August 15, 1980. Embrittlement of Cr-Mo steels in H/sub 2/S plus H/sub 2/O vapor environment

Description: The H/sub 2/S + H/sub 2/O vapor environment tests appear to yield data which is within the normal experimental scatter and serves to reasonably differentiate between the hydrogen resistance of candidate steel samples. A potential problem stemming from the deep side grooves, which promote advanced crack growth in the higher strength steels, can be overcome by reducing the side grooves to 25%. This is the optimum side groove depth recommended by deLorenzi and Shih.

Numerical modeling of the EBT-S ion-cyclotron heating experiment

Description: To determine the effect of ion-cyclotron heating on EBT-S plasma parameters, a one-dimensional, time dependent neoclassical model of plasma particle and energy transport was used. For EBT-S the code was run with the following parameters: B/sub O/ = 0.7 tesla (axial field at the midplane), B/sub O/ = 1.4 tesla (axial field at the throat), R/sub T/ = 150 cm (major radius), a = 15 cm (minor radius at the midplane).

LOFT Small Break Test Themocouple Installation

Description: The subject thermocouple design has been analyzed for maximum expected hydraulic loading and found to be adequate. The natural frequency of the thermocouple was found to be between the vortex shedding frequencies for the gas and liquid phase so that a tendency for resonance will exist. However, since the thermocouple support will have a restricted displacement, stresses found are below the endurance limit and, thus, are acceptable in respect to fatigue life as well as primary stress due to pres… more

Embrittlement of Cr-Mo steels in H/sub 2/S plus H/sub 2/O vapor environment. Quarterly report No. 8, May 15-August 15, 1980

Description: In previous tests the environment was H/sub 2/S of the highest commercially available purity. In this environment it proved impossible, by our current techniques, to induce hydrogen embrittlement in low yield strength (45 to 75 ksi or 300 to 500 MPa) samples which had been given a post weld heat treatment. The introduction of saturated water vapor in the H/sub 2/S has clearly served to give conditions in which the lower strength steels can be embrittled.

Evaluation of geopressured brine injectability: Department of Energy, Pleasant Bayou No. 2 well, Brazoria County, Texas

Description: A field evaluation of geopressured brine injectability was completed during September 22 to 25, 1980 at the DOE, Brazoria test site in Texas. Membrane filters, with pore sizes of 0.4-..mu..m and 10.0-..mu..m, were used as the basis for obtaining suspended solids data and for developing performance-life estimates of typical spent brine injection wells. Field measurements were made at 130/sup 0/C and line pressures up to 3800 psig. Scale inhibited (phosphonate-polyacrylate threshold-type, carbona… more

Laser cleanup of Pt group metals

Description: Due to increasing interest in chemical and fuel synthesis from syngas, the feasibility and practicality of purifying Pt group metals (Pd, Ru, Rh) using LIS technologies have been re-evaluated. Findings for the selective removal of /sup 107/Pd from Pd metal are described here. The selectivity of this technique is based on the angular momentum selection rules for atomic absorption of circularly polarized light. In principle, it is possible to selectively excite isotopes with non-zero nuclear spin… more
