Abstract
-
An experimental version of Ihe two-circuit backward-wave magnetron amplifier is described. The low-level operation shows a dependence of the gain on beam velocity and current similar to that of the equivalent O-type device. An over-all stable gain of 10 db is easily obtained. The eLfect of the spread of the magnetron beam is investigated. An attempt is made to correlate the experimental results with various theoretical models for magnetron operation. One thcoretical model is suggested which gives some promise in describing the interaction. Although characteristics of the present tube do not make it particularly interest&ng either as a small-signal or large-signal practical backward-wave amplifier, it has been vely valuable in giving information on the d-c beam model, and the character 0% growing waves on this beam. Recommendations are given for design modifications to make more practical tube for application purposes.
