Perturbative Approach for Fast and Accurate Evaluation of Quasi Axially-Symmetric Cavity Resonance Frequency in Drift Tube Linacs
By
Progress In Electromagnetics Research M, Vol. 93, 109-118, 2020
Abstract
In this paper we present an analytical method, employable with commercial full-wave electromagnetic CADs, which allows full-wave simulations of electromagnetically (EM) large structures, in terms of wavelength, such as linear accelerator cavities (LINACs) and a very accurate estimation of their operating frequency. The proposed technique is based on the exploitation of rotational symmetry through the definition of equivalent axially-symmetric volumes which replaces the non axially-symmetric ones inside the structure being analyzed. After a theoretical study, we show the successful application of the method in the real case study of a Drift Tube Linac (DTL) cell.
