Aerial Radiometric and Magnetic Survey of the Clinton National Topographic Map, NI 14-2 Oklahoma: Volume 1

Description: From objective and plan: The airborne data gathered were reduced using ground-based computer facilities to give the basic uranium, thorium and potassium equivalent gamma radiation intensities, ratios of these intensities, aircraft altitude above the earth's surface, total gamma ray and earth's magnetic field intensity, correlated as a function of geologic units indicated from available geologic maps. Results of analyses of these field data are presented as profile plots of the gamma radiation a… more

Assessment of methods for analyzing gaseous mixtures of hydrogen isotopes and helium

Description: Mass spectrographic methods have served well in the past to analyze gaseous mixtures of the hydrogen isotopes. Alternate methods of analyses are reviewed which offer wider ranges and variety of isotopic determinations. This report describes possible improvements of the mass spectrographic determinations, gas chromatography, anti-Stokes Raman spectroscopy, microwave-induced optical emission spectroscopy, and methods of measuring tritium using radiation detection devices. Precision, accuracy, lim… more

Micromachining of laser fusion target parts

Description: A 5W argon ion laser that operates CW is used. A broad band rear mirror is tuned to maximum power output. The beam is directed vertically by an adjustable turning prism, through a beam splitter, and then focused with an ordinary microscope objective lens onto the material to be cut. The beam splitter allows a telescope and television camera arranged to view the cutting through the same lens that is focusing the laser. The object to be cut is mounted on a micromanipulator which can move the obje… more

Monte Carlo efficiency predictions for a portable /sup 3/He neutron detector

Description: A small, manportable neutron detector using 18 /sup 3/He proportional counters arranged in 3 banks within a polyethylene moderator is described. Each counter is 25 mm in diameter and 340 mm long (sensitive length) and is filled with highly purified /sup 3/He to a pressure of 400 kPa (4 atm). Measurements of the detector efficiency were made using a calibrated /sup 252/Cf neutron source. Then, independent calculations of the detector efficiency were performed with the TART Monte Carlo transport … more

Super liquid density target designs

Description: The success of laser fusion depends on obtaining near isentropic compression of fuel to very high densities and igniting this fuel. To date, the results of laser fusion experiments have been based mainly on the exploding pusher implosion of fusion capsules consisting of thin glass microballoons (wall thickness of less than 1 micron) filled with low density DT gas (initial density of a few mg/cc). Maximum DT densities of a few tenths of g/cc and temperatures of a few keV have been achieved in th… more

Ion beam inertial fusion target designs

Description: A class of ion beam fusion targets consisting of a spherical shell of frozen DT surrounded by a low-density, low-Z pusher and a high-density tamper was designed. These designs have a number of advantages over targets with high-density, high-Z pushers.

Interferometric measurement of laser fusion targets

Description: One of the important parameters of hollow glass microsphere laser fusion targets is the wall thickness and uniformity. It was shown previously how a combination of white light and monochromatic light interferometry can be used to measure the absolute optical path through the center of a glass microsphere. The use of this technique to measure nonuniformities in microsphere walls is discussed. The way in which the actual optics used in the interferometer affect the wall thickness measurements is … more

Heat-to-heat variations of total strain; to 5 )3<: at discrete stress levels in types 316 and 304 stainless steel from 24 to 316

Description: Tensile tests were conducted on eight heats of randomly selected, mill-annealed type 316 stainless steel and seven heats of mill-annealed type 304 stainless steel at 24, 93, 204, and 316/sup 0/C to establish the effects of heat-to-heat variations on total strain (to 5 percent) at discrete stress levels. Factors of difference were established between maximum and average strain (corresponding to minimum and nominal yield strength material respectively) for regulatory analysis applications. Limite… more

Electron transport inhibition in spherical microshell target irradiations

Description: Recent laser irradiation experiments on spherical glass microshells have demonstrated the existence of inhibited energy transport through the dense plasma by electron conduction. Possible reduction mechanisms may include the effects from the ion-electron two-stream instability, self-generated thermoelectric magnetic fields, and resonance absorption fields. The results from numerical simulations, using different inhibition models, for selected experiments will be compared to the data of ''explod… more
