Magma fuel cell. [For energy extraction from magma or for electrochemical protection of heat exchangers in magma]

Description: A high temperature, solid-electrolyte fuel cell is described which uses molten rock having oxidizable constituents as a fuel. The principles of this magma fuel cell have been successfully demonstrated and power densities of 88 W/m/sup 2/ have been achieved. If power densities can be substantially increased, the magma fuel cell may find numerous applications in magma tap projects to increase the efficiency of energy extraction from magma sources or may provide the energy necessary for the electr… more

Morse Monte Carlo Radiation Transport Code System

Description: The report contains sections containing descriptions of the MORSE and PICTURE codes, input descriptions, sample problems, deviations of the physical equations and explanations of the various error messages. The MORSE code is a multipurpose neutron and gamma-ray transport Monte Carlo code. Time dependence for both shielding and criticality problems is provided. General three-dimensional geometry may be used with an albedo option available at any material surface. The PICTURE code provide aid in … more

Control of closed orbit deviation due to synchrotron radiation

Description: The energy loss by synchrotron radiation in electron-positron storage rings occurs in every bending magnet and is thus distributed around the ring, while the energy gain occurs at the rf cavities, which are usually lumped in only a few locations. This type of orbit distortion is usually negligibly small compared to the design allowance in existing synchrotrons and storage rings; however, in the case of the larger storage rings now being contemplated, the distortion can be substantial in compari… more

Transient response of three-layered rings

Description: Hamilton's principle is used to derive equations of motion for a linear elastic three-layered ring. The theory includes the effects of shear deformation and rotatory inertia in each layer and radial strain effects in the middle layer. A convenient computational technique is developed for transient response evaluation without resorting to finite-difference or finite-element approximations. A companion experimental study was conducted using three different rings. All rings had aluminum inner and … more

Monitoring sinusoidal vibration environments with a television system

Description: The development and prove-in work of this experiment established a technology for using television equipment to monitor hybrid microcircuits and other miniature assemblies in sinusoidal vibration environments. Production assemblies were run through sine vibration test sequences with television systems used to monitor the sequences. During the experiment different television lens systems were tried to obtain clean, sharp, highly magnified pictures of the assemblies being monitored. Successful mo… more

Gas laser cells: stress analysis of cylindrical cells with radial injection of electrons

Description: The problem is to develop a design procedure for pressurized cylindrical excimer laser cells. Excitation of the pressurized laser gas is by a short pulse of high energy electrons injected through the cell wall. In traversing the wall, the electrons lose energy and heat the wall. Because of rapid gas heating, a shock wave is generated which produces an additional load on the wall. Selected for analysis is a simple, conservative model of a cylindrical cell pressurized to double the shock pressure… more

Some developments in laser isotope separation research at Los Alamos

Description: The supersonic expansion of bulk gas samples to obtain low vibrational and rotational temperatures that allow detailed resolution of the infrared absorption features of isotopic molecules (/sup 235/UF/sub 6/ and /sup 238/UF/sub 6/) is discussed. (LK)
