Differential Voltammetry Using The Hanging Mercury Drop Electrode
"The general techniques of voltammetry with continuously varying potential have been applied to a differential method in which two electrolysis cells are used, each with a hanging mercury drop electrode. Using this method it is possible to determine lO/sup -6/ solutions with increased precision, and it is also possible to analyze solutions as dilute as 10/sup -6/ without removing oxygen from the electrolysis cells. Mixtures can be analyzed easily by adding individual components of the mixture to the reference cell."

Zircex Uranium Sublimate Loss
"One of the limitations of the Zircex Process is the large percentage loss of U which is carried off with the volatile ZrCl/sub 4/. Since the ratio of U to Zr in the fuel element is quite small (< 1%), a large percentage of U loss can be caused by small amounts of U in the ZrCl/sub 4/ sublimate. The U loss must be kept below 1% if the Zircex Process is to be adapted to industrial scale processing."

The Input Admittance of a Ring Circuit
"A ring circuit is a succession or two-port networks and at least one three-port network, each feeding the next at one port and the last feeding the first so that the sequence closes on itself leaving at least one input port. The input admittance is derived in terms ef various matrices describing the circuit for one- and two-input port rings."

Betatron Oscillations and Equilibrium Orbits in Terms of Amplitude and Phase Functions
"Formulas are given to express the general particle trajectory and the equilibrium orbit for a slightly disturbed synchrotron in terms of the amplitude and phase functions for the ideal machine. If these functions are known, orbit computations can be carried out by simple integration procedures. The formalism is expected to be useful especially for considerations such as beam alignment or generation of an external electron beam. Some equations given earlier are repeated for completeness."

Radiation Effects in Circular Electron Accelerators
"The effects of radiation emission on the motion of electrons in high energy synchrotrons are analyzed. The damping rates and quantum excitation of the three principal modes of oscillation are derived for strong focusing and constant gradient accelerators. Methods for correcting the radiation effects for strong focusing accelerators are discussed."

Analysis of Spurious Modes in Magnet Power Supply
"The resonant frequencies of the magnet power supply are investigated. It is found that there are eleven resonant modes in addition to the desired mode of operation with six additional resonant frequencies. From measurements of the choke model, it appears that the frequencies of some of the spurious modes may lie in the same range as the desired mode of operation."

The Design and Uses of High Flux Research and Test Reactors
The need for thermal and fast neutron fluxes in the range of 1 to 5 x l0/ sup 15/ neutrons/cm/sup 2/(sec) for the production of heavy elements such as Cf/ sup 252/ and other special isotopes and for improving the quality of beam experiments, reactor materials testing work, and solid state research has led to plans for the construction of three ultra high flux research reactors. The designs of these and other high flux research reactors are based on the general technology of enriched tank-type reactors; however, they utilize the principle of separate fuel and moderator regions to achieve flux peaking in these regions. Thus, proposed designs take the form of an annular fuel region with internal and external moderating regions or an under moderated core with an external moderator or reflector. In such arrangements, the thermal flux peaks in the moderating regions and the fast flux peaks in the fuel region, which results in maximum fast and thermal fluxes per unit of power. Since most of the moderation of fast neutrons takes place outside of the fuel region, the thermal flux peaking depends on the number of fast neutrons leaking from the reactor core, which in turn depends on …

The Response of Concrete Shear Keys to Dynamic Loading
A program for determining the behavior of concrete shear keys under dynamic loading similar to that encountered in nuclear blasts was coupled with a study of the comparative behavior of shear keys under static loading. The testing procedure gave deflection recording for the shear keys, their strength in pure shear, under transverse compression and when dowelled, stresses and strains in the embedded dowels, and the mode of failure of each specimen. From an analysis of the data obtained and a study of the combined direct and transverse stresses involved, important qualitative conclusions were drawn from the common trends in the behavior of keys. The tests proved that plain concrete keys can withstand stresses in pure shear as high as 2000 p.s.i. or more, that imposing transverse compression on them raises the ratio of their shear strength to compressive strength by about 50% in dynamic loading though by only about 5% in static loading, and that the keys exhibit much higher shear strength when subjected to dynamic loads than when stressed by static loads. The test also indicated that the strength and quality of the gravel are probably major factors governing the strength of the keys.

Transit Times of Compression Sound Waves Through Aluminum Plate
Experiments are described which show that the velocity of compressional waves along a thin plate varies as a function of the frequency of the waves. In terms of transit times in aluminum the value is between 4.02 and 4.94 microseconds per inch.

The X-ray Spectroscopy of Solids
This technical report is based on a a paper presented in October 1955 before the Symposium of the American Society for Metals held at Philadelphia. This is by no means an exhaustive review; selection of the material discussed was made according to the author's interests. Some of the work reported here was assisted by the Office of naval Research and the Atomic Energy Commission through contracts with the Ohio State University Research Foundation.

A Timing Circuit for the UCLA FM Cyclotron
A circuit had been constructed which supplied timing pulses for the various operating components of the UCLA F.M. cyclotron as well as counter gating pulses of variable widths and adjustable positions on the cyclotron duty cycle. The pulses are timed relative to a master pulse generated when the cyclotron oscillator passes through a specified frequency in the direction of decreasing frequency, thus giving only one master pulse per duty cycle. Overall stability of the timing circuit is about one mu sec.
