Multimegawatt Broadband Microwave Tubes
Abstract
Effort continued towards the development of a long slot traveling wave tube. Work was concerned with the measurement of insertion loss due to a radiating slot in the wall of the cavity. It was found that a minor misalignment of the cavities can cause drastic changes in the transmitted power as well as in the reflection at the couplers. On the centipede traveling wave tube major effort was directed toward a leaky wall structure for loop mode suppression in the range of observed backward wave oscillations of the experimental twt amplifier. Another major concern was the examination of the coupled mode analysis of a structure consisting of a periodic circuit coupled to a dielectrically-loaded waveguide. A new model of the electron stick was completed and procedures for the forthcoming tests are described. Investigation of the hollow beam gun indicated that the range of a solution to the equations of space-charge limited flow is determined mainly by the position of the critical points in the complex plane of the cathode. The work done in the study of cathode shapes in which such singularities do not exist is described.
