The transmitter upgrade replaces a 60 kW
crossed-field amplifier stage with a solid-state class C pulsed amplifier.
He then focuses on microwave vacuum electronics, explaining the physics and theory of the interaction of electron beams with electromagnetic fields in quasi-stationary systems such as diodes and klystrons, systems with continuous interactions such as traveling wave tubes, backward magnetrons and
crossed-field amplifiers, and systems based on stimulated radiation of classical electron oscillations.
Subject matter includes TWT transmitters,
crossed-field amplifiers, magnetron transmitters and solid-state sources.
The major topic of the first session on
crossed-field amplifiers, chaired by Robert Symons, of Litton, was the Navy-sponsored effort to lower the intrapulse noise levels of
crossed-field amplifiers.
