The following report analyzes interactions of K+ and K- mesons and measures their lifetimes using a nuclear emulsion technique.

Abstract: "The results of the investigation of three methods of obtaining transverse stability in linear accelerators for ions are presented and discussed. For electric or magnetic quadrupole focusing the range of stable operation, oscillation amplitudes, and the operation of an actual grid is analyzed from measurements of the field distribution. Finally, the formulas applicable to focusing by axial magnetic lenses are presented."

The following document analyzes one hundred and seventy-seven bevatron tau mesons for Q value of the tau decay, tau spin and parity, and possible polarization effects.

Thesis describing the the computation of eigenstates for a particle moving in a spheroidal potential well under the influence of a strong spin-orbit interaction.

Report discussing the trajectories of blobs of plasma as it travels across a magnetic field. Various observations are made about the blobs, such as the fact that they are diamagnetic, and that they can be either elastically scattered from each other or form a compound entity with a possible toroidal structure. "It is believed that these blobs are actually stable configurations of plasma and magnetic field, having both diamagnetic moment and spin."

From abstract: "Plamons (plasma-magnetic entities) are toroidal "packages" of plasma wrapped up in their own magnetic field. Experimental evidence for the existence of plasmons is adduced and theoretical considerations concerning their various types and their stability are discussed."

Abstract: "These notes were written from recordings of a series of lectures which Dr. Montgomery H. Johnson presented to the ARC Research Group of the University of California Radiation Laboratory, Livermore, during January, February and March of 1954. In the lectures he discussed plasma oscillations and the penetration of radiofrequency electromagnetic fields into plasmas. Dr. Johnson plainly did not attempt rigorous or exhaustive treatments of these subjects but rather contented himself for the most part with the introduction of ideas in the simplest manner possible."

Report discussing a study regarding the possibility of using shock ionization as a source for mirror-type thermonuclear reactors. This was tested in a one-inch vacuum system, and though initial ionization and temperature produced was low, the magnetic field extended the time of light emission and compressed the luminous region.

The following document describes suggestions on the application of the A-48 ion accelerator beam currents to the Sherwood Program.

From Abstract: "This paper deals with the vacuum design considerations of large systems involving the application of 8-inch through 32-inch mercury diffusion pumps. The selection, rating, and optimization of pumps are discussed along with the closely allied problem of baffling the pumps. The materials of construction and methods of fabrication to avoid subsequent system contamination are dealt with in detail. System interlocking and its associated instrumentation are illustrated by referral to the operation of a large particle-accelerator vacuum system."

A report discussing "an explosive ferroelectric power supply and the experimental approach followed in determining its operating characteristics."

Report discussing the status of the five main thermonuclear research groups at University of California Radiation Laboratory. The Mirror Machine program is given a more detailed description.

The following report demonstrates experimental verification of a method described in a previous paper--that involves measuring the dispersive microwave propagation coefficients simultaneously at several frequencies and comparing measured values with the values calculated for various distribution functions--and describes the procedure used to determine the distribution function in a sample laboratory plasma experiment.

The following report examines the trapping of charged particles, fast electrons especially, within the geomagnetic field.

The following report is a bibliography containing reports, books and journals on the production of high temperatures (2000-3000 F). The literature provided only covers to the end of 1957.

From abstract: "A relationship is derived that predicts the power radiated from the cathode to the anode of the plasma diode. The radiated power loss predicted by this relationship for a tungsten cathode and a nickel anode at widely different temperatures is found to be five times greater than the prediction of the conventional relationship which assumes gray-body conditions."

This report analyzes the High-Energy Electrostatic Plasma Gun, which is to be used for propulsion.

The coefficients of thermal conductivity of aluminum-bismuth metal-to-metal bonds, and of aluminum and bismuth surfaces in contact under pressure, were measured.

"Preliminary results are given for pumping neutral hydrogen gas in 1-second pulses by the gettering action of an evaporated coating of molybdenum. One second gas in-puts are observed at equivalent pumping speeds > 10-4 liters/second at 1 x 10-(-8) mm Hg in a 70-liter volume system. Base pressures <1 x 10-(-10) mm Hg are achieved by gettering with the static evaporated coating and pumping with a 4 in. oil diffusion pump simultaneously. Criteria for choice of gettering metal and a brief outline of pumping requirements for controlled fusion devices called Pyrotrons are included."

Abstract: Further work has been done towards developing a high-output hydrogen ion source using the principle of the Ti ion source, the release of ions from hydrogenated titanium. It is concluded that previous efforts had resulted in the production of large quantities of low-energy ions but had failed in the attempt to accelerate a significant fraction of these. A new approach is undertaken that involves an entirely different geometry. Successfully accelerated and focused beams are obtained. Performance data and mass-analysis distributions are given. The problems of extraction and scaling are discussed. Future subjects of investigation are outlined.

The following quarterly report covers the period of July through September of 1950, split into three reports discussing the metabolic properties of plutonium and allied materials, biological studies of radiation effects, and health chemistry and physics.

The power of nuclear track research emulsion as a fast neutron dosimeter is examined in the exposure of a human phantom to PuBe neutrons. Semiautomatic track scanning and high-speed data analysis obviate the major disadvantages of this dosimeter, and allow the following basic information to be obtained without a serious cost in time: the rulative proton recoil energy spectrum, the absolute differential proton track den sity spectrum, and the average proton recoil energy at various locations in the phantom. From this are calculated the total absorbed local tissue doze due is proton recoils, the local thermal neutron intensity, and that portion of the tissue doze due to thermal [formula] tracks.

The motivation for the measurement of the angular distribution of elastic scattering of medium energy protons and neutrons has been clearly presented by others. They have also listed the results obtained prior to their experiments at 31.5 Mev. This is a report on some results obtained with 30.6 Mev protons scattered from Be, C, and Al.
