Auto-acceleration in an iris loaded pipe

Description: Calculations for the process of auto-acceleration in an irisloaded pipe are presented. The electrom-agnetic fields generated by the beam current are calculated. Particle dynamics equations are given which consider only the axial motion of the electron. Also, results are given for calculations on a beam current rising linearly with time at the rate of 1700 A/ns. (WHK)

Nuclear in situ recovery of oil from oil shale

Description: A plan is presented for production of oil by retorting oil shale in situ after breaking it with underground nuclear explosives. Reserves of oil shale of thickness and grade suitable (greater than 20 gal/ton) for this process occur in the Piceance Creek Basin of Colorado, and are estimated to contain 640 billion barrels of oil in place. Cost projections indicate that this oil could be produced at a price ranging from 00 to 30 at the wellhead with a 20% rate of return on investment (discounted ca… more

Preparation of fission foils for fission ionization chambers using a painting technique

Description: Fission foils for use in fission ionization chambers were produced by painting metal substrates with coats of fissionable isotopes. Areal densities as large as 2.0 mg/cm/sup 2/ were obtained with excellent adhesion. This painting technique has been successful in depositing isotopes of uranium, plutonium, americium, and curium on metal substrates made of beryllium, aluminum, copper, and nickel. The cost of this painting technique is estimated to be approximately one-tenth the cost of producing f… more

Problems with predicting fallout radiation hazard in tactical battlefield situations

Description: Prediction capabilities are reviewed to determine whether they are suitable for describing the fallout radiation hazards that may exist in tactical nuclear battlefield situations. One aspect of fallout predictability is illustrated by a collection of aberrant results from nuclear tests conducted under fairly stabilized conditions. There are a number of warnings about the confidence that should be placed on prediction schemes derived from nuclear test shots. A comparison of current fallout model… more

Project Rio Blanco spall measurements data report

Description: A major instrumentation program was undertaken for the Rio Blanco experiment using accelerometers and velocity gages buried at various depths below the ground surface and at various horizontal ranges from the emplacement well. The objective was to physically measure the depth and aerial extent of spall (tensile failure of the earth material). Data from each of the instrument stations is given, along with the appropriate integrated data for particle velocity and displacement or just displacement… more

Stage III dislocation pinning in silver resulting from gamma irradiation

Description: A brief summary of the history of research in the fields of radiation damage, point defects, and dislocation effects is presented. Theory and previous experiments are discussed. Apparatus capable of continuously measuring changes in the elastic modulus and internal friction during gamma irradiation over the temperature range from <4 deg K to well above room temperature is described. A novel hollow-cylinder sample geometry permits use of a source strength of only 1 Ci. Survey experiments over a … more
