A 704 Program for Computing Thermal Neutron Spectra in Infinite Homogenous Media

Description: A flexible program has been prepared for solution of the neutron balance equation in an infinite homogeneous medium. This program is specifically designed for studying the effects of varying the energy transfer kernel on the resultant neutron spectrum. A rapidly converging iterative procedure is employed. The equation to be solved and the specific input information required by the program in order to compute spectra are explicitly stated. No discussion of the physics of the problem is given.

Review of the Surface Interaction Theory of Rearrangement and Inelastic Collisions

Description: Deuteron reactions assumed new importance when it was found that the angular distribution of the outgoing particles in d-p and d-n reactions displayed a great deal of structure. Bhatia, Huang, and Butler showed that the structures of the angular distribution of the outgoing particles in d-p and d-n reactions is directly related to the angular momentum of the captured particle. Early studies of deuteron stripping fractions were reviewed and summarized by R. Huby. Additional work was reviewed, an… more

Effect of R.F. System on Betatron Oscillations

Description: The change in betatron frequency due to the focusing action of the radiofrequency cavities is calculated. It is found that at injection the fractional change in radial betatron frequency for particles with small phase oscillations is given by -0.025V, where V is the maximum r-f voltage per turn in Mev. There is an equal and opposite change in the vertical betatron frequency. Also it is proven, in a general manner, that the damping rate of the betatron oscillations is independent of the nature o… more

Free-Free Gaunt Factors

Description: The hydrogenic (unscreened coulomb) free-free gaunt factors are computed for a wide range of initial energies and photon frequencies. In addition, an average over initial energies with the Maxwell-Boltzmann distribution is performed to give the temperature-average gaunt factors for use on opacity calculations. The relation between these gaunt factors and the rate of bremsstrahlung energy product is given as is the total energy emitted.

Time Variation of Thermodynamic Parameters of a Gas in the Region of a Shock Front : Progress Report III

Description: The original goal of this investigation was to compare the thermodynamic characteristics of the gases in and behind the shock fronts in gases at initial pressures in the millimeter range and to compare these characteristics in the geometries of single and double discharges. The shock fronts were not visible, so it was not possible, at these pressures, to get visual data from the shock front itself. The parameters giving the properties of the gases were faces. Measurements made with an image con… more

Sampling the Upper Atmosphere for Particulate Matter. First Quarterly Progress Report, June 15 to September 25, 1959

Description: An analysis to screen the various particle-collection systems which might be used for sampling the upper atmosphere with a rocket sampling vehicle has been undertaken. Although the current model of the Goetz Aerosol Spectrometer is not suitable, a high-flow-rate sampler of this general type, if it can be designed, appears promising. The design of such a sampler will be undertaken in future work. If a workable design is possible, this method would appear to be the most promising of all.

Some Design Considerations for the Megatron Coil

Description: The relation between the maximum permissible transverse energies of particles that can be focused, the azimuthal energy, and the beam width is discussed relative to Megatron coil design. It is shown that deep potential wells for focusing can be obtained only at the expense of a narrow beam. (C.J.G.)

Present Status of Semiconductor Particle Counters

Description: This review lists some of the salient features of semiconductor particle counters and cannot claim to contain an exhaustive listing of all the work in the field. Performance results on the surface-barrier counters as developed at California Institute of Technology are included as typical for this type of counter, though comparable results have been obtained elsewhere.

Leveling of Extraction Tool Crane Rails. Section I. Second Performance. Core I, Seed 1. Test Results DL-S-246, FY-59-323

Description: The purpose of the test was to check the extraction crane rails in the area of the reactor pit for level and parallelism. The west extraction crane rail exceeded the allowed tolerance of 1/32 inch at only one location. The elevation of the north bumper was out of tolerance by 1/64 inch. The east extraction crane rail was consistently lower than the west rail by as much as 8/64 inch. The east rail was parallel with the west rail within allowable tolerances over the length tested except at one lo… more
