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.

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."

A Transistorized Binary Counter for Extreme Environments

Description: A transistorized binary counter circuit is described that operates over a temperature range of -65 degree F to +165 degree F. the supply voltage is 28 + 4 volts and the maximum trigger repetition rate is 5 kilocycles. the binary circuit is pre-settable and resettable by means of a switching arrangement that can be mechanized. Texas Instrument type 904 silicon transistors whose large signal current gain is 2.8 or greater at a -65 degree F can be used in this circuit.

A Study of Location Times for Positions Arranged on a Panel in a Random and an Ordered Manner

Description: The results of an experimental pilot study on the location time, for a sequence of N specified positions on a panel, are given for 1 <_ N <_ 30. The positions to be located were randomly arranged on one set of panels and arranged according to an ordering scheme on a second set of panels. Th location time for N positions randomly arranged on a panel varies approximately as N(2). In the case of an order arrangement the location time is essentially proportional to N. Even for as few as 30 position… more

Frequency Components of a Step Function and a Sinusoid

Description: Fourier analyses are made on two functions. The first is a step function forward from periodic samples of a sinusoid. If the frequency of the sinusoid is less than one-half of the sampling frequency, it is shown that the step function has no frequency components less than one-half of the sampling frequency other than that of phase, and duration with respect to the interval of the analysis. It is shown that the insertion of a blank space in the period of analysis reduces greatly the uncertainty … more

The Equation of the Fusion Curve

Description: A generalization of the Lindemann law is used in connection with the Murnaghan equation of state for a solid to derive theoretically the empirical Simon equation for the fusion curve. For the alkali metals it is shown that experimental values of the temperature exponent in the Simon equation are quantitatively compatible with the theoretical evaluation given, and, furthermore, that the theory can predict approximate values of the experiment, in practice.

Equipment and Preliminary Results for the Leaching of UO2 in a Basic Carbonate Circuit

Description: Equipment has been designed and constructed for the purpose of leaching pure uranium minerals in both acidic and basic circuits. This equipment provides a means for removal of a series of samples during any one run, control over speed of agitation, indication of gas over pressure, and automatic temperature control. These units may be operated up to 1500 p.s.i. Solid UO2 samples were prepared by sintering under hydrogen to 1800 degree C. Preliminary results of the leaching of sintered UO2 in a b… more
