Title: Radio frequency tuning of dressed multicell cavities using pressurized balloons

Abstract

Methods and systems for non-invasively tuning dressed multicell cavities. A multicell cavity can be plastically deformed as result of introducing a customized balloon to a cavity and then pressurizing the balloon to a targeted cell while applying a global force on the cavity flanges. The pressurized balloons localize the plastic deformation to the targeted cells using prescribed values of both global force and balloon pressure. Such an approach allows for the tuning of dressed cavities without removal of the helium vessel.
