|Title:||Design and Simulation of Klystron Tube and Q-Factor Improvement Using Cavity Perturbation|
Yadav, Rana Pratap (Guide)
|Abstract:||The advent of vacuum tubes, klystron being one of its kind is regarded as revolution in the field of communication. The most efficient use of such tubes is in transmitters and receivers as amplifiers, along with this various other vacuum tubes found its application in different scientific and commercial fields as well as in devices such as cathode ray tube. The various other fields in which these tube amplifiers find its usage is spectroscopy and imaging devices, remote sensing, space research and high-data-rate wireless communication etc. It has been deduced that efficiency is the most important parameter. Hence constant efforts are being made to increase the Q-factor i.e. quality of the tubes by any means which is one of the ways to make its working more efficient. In the work been done the design and simulation of 2.7 GHz klystron has been discussed. The cavity of klystron is designed and simulated using CST Studio Suite software. The Q-factor of the cavity is initially found to be 12695 which is not up to the desired value. In further trail, Q-factor of the cavity is improved using Cavity perturbation method. Here a structural change based on the analysis, called perturbation is incorporated in cavity design. The adopted perturbation significantly enhanced the Q-factor up to 13304 without having any significant effect in operating frequency klystron. It is the discussion of only one method i.e. through cavity perturbation to improve the quality of the vacuum tube (klystron) whereas there are many others ways as well one being electropolishing or coating with materials like titanium etc.|
