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.
traveling wave and backward wave tubes of M-type, magnetrons, crossed-field amplifiers, MILO)
The book consists of two parts: Part I focuses on the motion of charged particles in static fields, the theory of electron lenses, and the problems of formation and transport of intense electron beams are considered; Part II covers the principles and theory of the interaction of electron beams with electromagnetic waves in quasi-stationary systems (diodes, klystrons), systems with continuous interactions (traveling wave tubes and backward wave oscillators), crossed-field systems (traveling wave and backward wave tubes of M-type, magnetrons, crossed-field amplifiers.
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
Raytheon's efforts in 35 GHz crossed-field amplifiers
(CFAs) have produced a tube with 10 dB of gain, 2 GHz of bandwidth, and 22 percent efficiency.
