Title
Magnetron valves for ultra-short wavelengths
Description
The article begins by considering oscillations of ultra-short wavelength, and the inherent limitations of the familiar triode circuits in producing, amplifying and detecting such oscillations.
It goes on to introduce a valve which suffers less from these limitations since the electron paths are modified by the presence of a constant magnetic field.
Information on this device is presented under these headings:-
The use of a magnetic field in valves for generating ultra-short
wave oscillations;
Negative resistance or “Dynatron” oscillations;
Electron resonance or “electronic” oscillations;
The “intermediate” wavelength range: Behaviour of
magnetron valves in the intermediate range;
Operating characteristics of magnetron valves;
Field magnets;
