Modeling same-order modes of multicell cavities

TL;DR

This paper derives and validates a transfer function model for parasitic same-order modes in multicell cavities, aiding in understanding and mitigating their effects in accelerator systems.

Contribution

It introduces a new transfer function model specifically for parasitic same-order modes in multicell cavities, validated against experimental data.

Findings

Model accurately predicts parasitic mode behavior.

Comparison shows good agreement with measurements.

Provides a tool for cavity design optimization.

Abstract

We derive the transfer function of a multicell cavity with parasitic same-order modes (from power coupler to pickup probe). The derived model is discussed and compared to measurement data.
