Frequency Dependent Capacitive-Inductive Model for Axially Coupled PI/2 Standing Wave Biperiodic Structures

摘要

The axially coupled pi/2 biperiodic, standing wave accelerating structure is analyzed. Two models for chain coupled cavities are considered, firstly the model with inductive coupling between the cavities, and secondly the capacitive-inductive model with frequency dependence of the coupling element. It is shown by comparison with experimental results, that the second model is better suited to describe the dispersion relation of the structure. Calculations of the parameters of dispersion curves for both types of coupling are given together with experimental results. 4 refs., 5 figs., 2 tabs. (Atomindex citation 20:034517)
