CORE TRANSFER FUNCTION MODELS FOR SNAP SYSTEM KINETICS

Description: A distributed parameter transfer function is developed for SNAP type reactor cores. The coolant may be either boiling, non-boiling, or both. In the boiling case the Bankoff model is used to find the spatial distribution of voids. The transfer functions obtained are not simple polynomials. However, they are readily analyzed for stabilily using the 7090 program TRAFIC, which uses a Nyquist diagram approach. Some general conclusions resulting from these calculations are included. (auth)

FORTRAN Programs for Computing Angular Distributions and Q Values of Nuclear Reactions

Description: Three Fortran programs, written for the IBM-704 computer, process the data from multichannel pulse-height analyzers in order to derive the Q values and differential cross sections of the groups observed. The standard deviations of the derived Q values and of the differential cross sections are also computed. With another program that was written, the effects of impurities can be subtracted from pulse-height spectra observed when a target contains a mixture of nuclides. A fifth program computes … more

Studies of the Rapid Beam Ejector at the Cosmotron

Description: Extraction of the external beam of the cosmotron with maximum efficiency and minimum duration for measurements of the magnetic moment of the lambda hyperon requires addition of a rapid beam ejector (RBE). Early experiments with the RBE give lower ejection efficiency than the standard ejection system. Reconstruction of the RBE with lengthening of the rise time of the system gives improved values. Computer studies that involve solving the equation of motion for the radial betatron oscillation wit… more

MODE IDENTIFICATION IN THE IRIS-LOADED WAVEGUIDE OF A RF PARTICLE SEPARATOR

Description: A description is presented concerning model measurements which were necessary to determine the geometry of brazed or electroformed prototypes for deflecting waveguides. A systematic investigation was also made of other than deflecting modes to ensure nondegenerate field solutions at selected operating frequencies. (J.R.D.)

ULTRASONIC ATTENUATION IN LEAD

Description: The absorption of longitudinal ultrasonic waves was studied as a function of transverse magnetic field in pure single crystals of lead at 1.2 deg K. The results were found to be generally consistent with the Fermi surface of lead suggested by Gold. In particular a detailed study of the magneto-acoustic oscillations, as a function of sample orientation and field direction, allowed the determination of some of the dimensions of the hole surface in the second Brillouin zone and revealed a number o… more

BEAM EXPERIMENTS WITH THE MURA 50 Mev FFAG ACCELERATOR

Description: Experiments on betatron oscillation frequency, beam life times, multiturn injection, longitudinal bunching, acceleration through the transition energy, energy spread in the accelerated beam, beam stacking procedures, effects of clearing neutralizing ions away from the stacked beam, and instability of the stacked beam are reported.

REPORT OF THE QUALIFICATION TESTING OF SNAP 10A FIXED RESISTORS

Description: Upon completion of the initial visual examination and dimensional check, the resistors were weighed and the weights were recorded. The measurement of insulation resistance, performed with a megohmmeter, indicated infinity for each resistor. The dielectric strength test was performed with a high potential a-c dielectric strength tester. The test voltage was applied with no evidence of leakage or breakdown in any case. A wheatstone bridge was used to measure the d- c resistance of each resistor. … more

Program for the Location of Fourier Peak Centers. Final Report of Program 4.10.27

Description: The computer program MET-146, in FORTRAN, locates maxima on Fourier (or Patterson) maps from 27 surrounding points in the 3-dimensional Fourier case and from 9 points for a 2-dimensional case. Input, output, and operations are described. Results obtained with this program are compared with those from other programs and from analytical extrapolation. A test problem is also included.

PLASMA DIAGNOSTICS WITH SHORT ELECTROMAGNETIC PULSES

Description: The propagation of short electromagnetic pulses in an ionized medium and the reflection of transient pulses from bounded ionized regions is discussed. Analyticai expressions for transient oscillations in reflected and propagated electromagnetic fields excited by a unidirectional pulse are derived for certain simple cases. The transient oscillations show a periodicity that is directly related to the plasma frequency and are useful for nearly instantaneous plasma diagnostics. An experiment is des… more

HEAT TRANSFER IN OSCILLATING FLOW. Aeronautical Engineering Report No. 483-e, June 30, 1963

Description: Pressure oscillations imposed upon a compressible fluid flowing in a duct produce a substandtial increase of heat transfer between the heated duct wall and the fluid. An experimental investigation was made of the causes of this increase. Resonant conditions in a duct were used to achieve increased oscillating amplitudes. The local heat transfer incresse was found to be highly dependent on the amplitude of the local velocity oscillations, and to depend also on the frequency of oscillations and t… more

The Structure of Heavy Nuclei: A Study of Very Weak Alpha Branching

Description: Very weak alpha branching in heavy elements was studied by a recently developed coincidence technique. This technique makes it possible to measure the energies and intensities of both alpha -particle groups and de-exciting radiation, even when the transition intensities are as low as 10/sup -8/ relative to the most intense alpha group. Twenty alpha -particle emitters from Po/sup 214/ to Fm were examined. 00+ states (beta vibrations) were observed in six even-even nuclei, and analogous states we… more

Fuel Cycle Program. A Boiling Water Reactor Research and Development Program. Eleventh Quarterly Progress Report, January-March 1963

Description: Even though VBWR shutdowns were required for location and removal of five failed fuel assemblies (HPD Program), the increase in fuel exposure was good. Fuel exposures wili pass the values at which cold worked stainless steel cladding was failing under the HPD Program. Failure of the 0.005-inch cold worked stainless steel clad fuel rods in assembly 8L was traced to strain cycling fatigue. A study of tapered fuel rods indicates a potential advantage for us of a variable water/fuel ratio along the… more
