Electron densities and mean collision cross sections are deduced from measurements of the propagation constant for microwaves in a plasma. From the electron collision cross-section measurements, inferences are drawn concerning the slope of the cross-

A base layer transit time analysis has been made for high-frequency transistor base donor distributions. Transit time is defined as stored charge per unit emitter current. The emphasis on the stored charge/current ratio is particularly pertinent to h

The garnet materials system has provided the basis for a rapid fundamental transformation of cylindrical magnetic bubble-domain materials technology from one based on bulk single crystals to one based on epitaxy. Recent developments are reviewed in a

To limit the 4080-mc local oscillator signal power input to the beat oscillator modulator of the Telstar satellite communications repeater, a subsidiary absorption limiter was used which consisted of an optically polished sphere of single-crystal ytt

Recent advances in the liquid phase epitaxial growth of rare earth magnetic garnet films have enhanced prospects for a bubble mass memory. It is the purpose of this paper to review the status of materials in order to achieve some perspective. Princip

The electrical cleanup of helium on molybdenum surfaces has been investigated. In this case, the phenomenon can be described by a trapping of ions upon impact with the surface. Measurements of the trapping efficiency η (atoms removed/ions collected)

Conditions are examined for the resonance transfer of an electron between a metal and an ion or an atom in close proximity to the surface. The point of view is that of Franck-Condon crossings of potential energy curves of the initial and final states

Localized ion implantation through photoresist masks has been used to produce rails which guide bubbles in garnet epitaxial films. Implantation expands the lattice so that the implanted regions are in lateral compression. In garnets with negative mag

It is now possible to design a class of low level, milliwatt range ferrimagnetic microwave limiters which exhibit distinctive characteristics and important advantages over previously reported ferrimagnetic limiters. The limiter characteristically con
