300-KV Pulser Transformer and Pulser.

Description: Photographs and working drawings are presented for a small (approximately 4.25 X 7 X 9 inch) 300Kv pulse transformer having double-conical secondaries each with a corona ring at its greatest diameter. The pulser circuit is shown but no text is included.

Flux in a Rectangular Cavity.

Description: A problem proposed by E. Hart to determine whether there are locally high or low neutron densities at the corners of a cubical cavity in a graphite lattice. To simplify the computations consider an infinite two dimensional lattice with a square cavity that has a point source of neutrons at the center (see Figure 1).

The Distribution of Pu(VI) and Pu(III) in Thenoyltrifluoracetone-Benzene-Nitric Acid Mixtures

Description: The distribution coefficients of Pu(VI) and Pu(III) have been measured as a function of the TTA, hydrogen ion, and nitrate ion concentrations in the TTA-benzen-nitric acid system. The extraction constants for Pu(VI) and Pu(III) are 1.4 X 10(-2) and 2 X 10(-5), respectively.

Modes of Acceleration of Ions in a 3-DEE Cyclotron.

Description: The analysis shows that a symmetrical three-dee cyclotron accelerating ions below relativistic velocities has the property that ions of different e/m rations can be accelerated without changing the frequency of the electrical power supplied to the dees or the value of the magnetic field. The energy gain per revolution of the ions which can be accelerated in the various modes are found, considering three identical dees of arbitrary angular widths. For these calculations it has been assumed tha… more

The Heat and Entropy of Ionization of Anhydrous Acetic Acid.

Description: Studies of ionic entropies in methanol and ammonia have led to the suggestion that ionic entropies in water are abnormally high. An explanation of this hypothesis may be given in terms of entropies of solvation and the high degree of hydrogen bonding in water. When an ion enters water, more disorder is created than when it enters another, less hydrogen-bonded, solvent.

Effect of Inositol and Octadecyl Alcohol Feeding on Lipoproteins in Cholesterol Fed Rabbits.

Description: A controversy exists as to the effect of inositol and other lipotropic agents on serum cholesterol levels and atherosclerosis in humans and animals. There is no general agreement that these agents lower serum cholesterol levels or exert an inhibitory effect on the development of atherosclerosis.,

The Biological Behavior of Organic Compounds Containing Radiophosphorus

Description: The study was undertaken with the objective of observing the distribution in the rat of organic compounds of phosphorus labelled with the P32 isotope as tracer. The fate of several of these compounds was studied in animals bearing tumors. The distribution of inorganic phosphate in animal tissues is well known but was included in this work for comparison with the organic phosphorus compounds.

Chemistry Division Quarterly Report: September, October and November, 1948

Description: A quarterly report consisting of reports published on Transuranic Elements from the University of California Radiation Laboratory. Each report is a brief one to two page summaries of the article submitted for publication during the months of September-November, 1948.

The Chelate Process: [Part] 5. Investigation in Horizontal Extractors

Description: The recovery of plutonium has been demonstrated in a laboratory countercurrent horizontal extractor using the TTA process. Using three extractive stages and two washing stages in each step, a recovery of 91 percent has been obtained in the chelation step and a recovery of 99.9+ percent in the de-chelation step. With five extractive stages, recoveries of 94-98 percent have been found for the chelation step.

Summary of the Research Progress Meeting of September 1, 1949

Description: The absolute excitation functions for the production of fission by charged particle bombardment in several substances were investigated at both high and low energies. The low energy work was done at the 60-inch Crocker cyclotron with alpha particles and deuterons, while the high energy work was done at the 184-inch cyclotron with alpha particles, deuterons, and protons.

Procedures in Magnetic Measurements at the University of California Radiation Laboratory, Berkeley: Fields Which are Constant or Vary Slowly with Time

Description: The flux standard is a device which will give a known flux-linkage change to be used as a calibration. At the Radiation Laboratory, two types of flux standards are used, a stationary type and a portable type.

Use of the Characteristics of Permalloy in Detecting a Predetermined Value of Magnetic Field or Current in a Time-Varying Electromagnet: 1/4 Scale Bevatron Operating Model, Magnetic Field Strength-Magnet Current Correspondence

Description: In programming the sequence of events in the operational cycle of the bevatron, certain devices must be triggered at specific values of magnetic field strength in the gap. It is desirable that the time-jitter, which corresponds to field jitter, of the tirggering pulses be small. In the synchrotron this is done with peaking strips which are located in the fringing field of the gap.

Method of Operation of the Permeameter

Description: In H measurements, the measured flux-linkage change represents twice the value of H to be plotted. In B measurements the bucking coil links flux equal to the air-flux in the B-measuring coils. The measured flux change therefore corresponds to twice the flux of intrinsic magnetization in the sample.

Studies in Beta and Gamma Ray Spectroscopy

Description: The study of artificial radioactive isotopes is at the present time one of the most important topics in nuclear research. It involves the establishment of a detailed term scheme for the disintegration in question. Not only are the energies of the components of the different beta and gamma radiations of interest, but also their intensities. These data give information concerning the probabilities of transitions between the different nuclear energy levels. From them it is possible to draw con… more
