In this paper, we present an analytical method, employable with commercial full-wave electromagnetic CADs, which allows full-wave simulations of large electromagnetic (EM) structures (i.e., 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 replace 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.

Abstract
In this paper, we present an analytical method, employable with commercial full-wave electromagnetic CADs, which allows full-wave simulations of large electromagnetic (EM) structures (i.e., 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 replace 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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
