Relations Governing Low Cycle Fatigue : a Summary of the Pertinent Literature

Description: The information available to date on low-cycle fatigue, resulting from either repeated mechanical straining (strain cycling) or from repeated temperature changes under restraint (thermal cycling and thermal shock), their relation to static and conventional fatigue properties, and their fundamental significance is assembled. In spite of the small amount of data accumulated on the effects of the numerous variables involved in low-cycle fatigue these data appear to conform to certain significant r… more

Control of Oscillation Amplitudes

Description: This report analyzes methods of correcting for the anti-damping of the radial betatron oscillations. Practical methods of reducing the anti-damping are to couple the radial and vertical betatron oscillations by means of a rotated magnetic quadrupole lens, or to add a magnetic structure which has a decrease in radiation loss for increasing radius of particles. It is shown that the damping ration cannot be changed by shaping the R.F. cavities.

Theory of the Thermal Breakaway of a Pinned Dislocation Line with Application to Damping Phenomena

Description: An investigation is made of the model of a pinned dislocation line under stress. The model used is that originally given by Koehler and later employed by Granato and Lücke in their theory of mechanical damping due to dislocations. By taking into account thermal fluctuations the probability of the thermal unpinning (breakaway) of such a dislocation line is calculated. The effect of the breakaway on the decrement and apparent modulus change felt by a stress wave traveling though a solid is also c… more

Irradiation Damage at Low Temperatures in the Noble Metals

Description: During the past year a great deal of new experimental information has become available concerning the nature of the damage produced in the noble metals by nuclear irradiation. In addition, several new theoretical calculations have appeared. The present survey attempts to asses our knowledge of the field. In particular, it attempts to five an atomic description of the natures of the damage introduced and of the changes which occur during thermal annealing in the novel metals below 60 K.

Kinetics of Dissolution of UO2 in Sulfuric Acid

Description: "Sintered U0/sub 2/ samples were leached in sulfaric acid solutions of various concentrations. A pressurized system was used so that it was possible to investigate the kinetics of the reaction to 270 C with oxygen overpressures as high as 900 psi. The rate was observed to be a function of the concentration of hydrogen ions and directly proportional to the partial pressure of oxygen. Evidences are presented which indicate that a U0/sub 2/ surface site reacts with a molecule of water to form a hy… more

Design and Construction of the High Density Concrete Shielding for the Engineering Test Reactor

Description: "Economic studies showed that high-density concrete made with magnetite was the most feasible choice from a cost and construction standpoint. Except for a few precautions, this concrete can be placed in essentially the same manner as conventional concrete. Concrete of any strength can be made, within reason, but for concretes having strengths of less than 4,000 psi at 28 days, extra fines must be added to the mix to lend supporting power and lubricity to the paste. Modulus of elasticity and Poi… more

Transient Beam Loading In Linear Electron Accelerators

Description: "The subject of beam loading in linear electron accelerators has been discussed. With suitable design it is possible to place the equilibrium electron phase angle well ahead of the crest of the traveling wave in the accelerator. With beam loading the equilibrium position will move toward the crest, but the electron energy will remain constant or nearly so over a considerable range of loading. Some loss in energy will result from moving the equilibrium phase angle off the wave crest but the spre… more

Theory Of The Constant Gradient Linear Electron Accelerator

Description: "The effect of beam loading upon the design and performance of the accelerator is examined. Results are given in dimensionless form so that the various equations and grams can be used at any operating frequency. The constant gradient accelerator is somewhat less subject to beam loading than the uniform accelerator structure. For an accelerator of given filling time and 20% more."

A Report on the Kinematics of High Energy Electron Scattering

Description: "A convenient summary is given of useful formulas on the kinematics of high energy electron scattering together with a derivation of the relevant formulas for transforming from the center of mass to the laboratory system such parameters as scattering cross sections. The formulas derived hold for any two- body collision: the approximation (m = 0) employed for the electron scattering calculations is rigorously true for the elastic scattering of photons."
