Matching and Power Coupling

Accelerator Physics 2026-05-19 v1

Abstract

A key factor in any RF system is the mechanism for coupling the RF power from an amplifier into an accelerating cavity. Any tranmission line will experience reflections if there is a mismatch in the impedance between the line and its load. In accelerating cavities due to their high quality factors there is often a large mismatch between the cavity shunt impedance and the tranmission line. This lecture will look at how to overcome this mismatch and ensure efficient coupling without steady-state reflections in both standing-wave and travelling-wave cavties.
