<p>11 A BACKWARD WAVE OSCILLATOR TUBE FOR THE PRODUCTION OF MICROWAVES The present invention relates to a backward wave mode oscillator tube, the delay line of which is in two sections of dissimilar length both operating in the backward wave mode, aligned in the direction of propagation of the electrons of the beam, the second being substantially shorter than the first and exhibiting a structure homothetic with the first in the ratio ? n being an integer, with a load arranged at the end of this second section which is adjacent the electron-gun, in which load is picked th up electromagnetic energy on the n harmonic of the predominant component of the wave in the first section.</p> |
