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.

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.

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."
