Abstract
A method has been established to accurately calculate cold-test data for helical slow-wave structures using the three-dimensional (3D) electromagnetic computer code MAFIA [Kory, 1996]. Compared with the experiment data, absolute average differences across the bandwidth of 0.2% and 3.4 Ohms for the dispersion and impedance, respectively. The computer code MAFIA is also used in this analysis to determine the effect on dispersion and on-axis interaction impedance of the wedge support rod geometry parameter variation.
