Analysis of High Power RF Windows for Gyrotrons.
Abstract
The project was undertaken to simplify the multidisk dielectric window design process for gyrotrons. This procedure has been involved in analyzing the response of many discrete combinations of high power radiofrequency window thicknesses in an effort to locate the optimum configurations. This report presents a method of numerically optimizing the design procedure. That the window region of the gyrotron is severely overmoded, so care must be taken that the window must be able to pass the energy contained in the high power modes to avoid overheating or reflection. To this end, the first part of this paper deals with a numerical solution of Solimar's modified telegraphist equation, which allows for the mode content intercepting upon the window to be found. The actual window design optimization is accomplished through the use of an n dimensional simplex method, where n is the numbr of window elements. Criteria delineating the search region are presented as well as typical problems which could be encountered during the optimization process. Results are given for both the mode content and the optimization. Mode content was compared against results given by a comparable proven algorithm, while window parameters were checked against existing designs. As will be seen, correlation in both cases was very good.
