Abstract

In particle accelerator components, parasitic resonances must be reduced because they heat up theequipment and cause beam instabilities. In this paper, a method for designing and characterizingHigher Order Mode (HOM) couplers for reducing such resonances in a broad bandwidth is proposed. Acase study is considered for a specific component, called QuattroTank, showing geometrical discontinu-ities and thus causing significant electro-magnetic resonances. Results of numerical simulation andexperimental emulation prove the capability of the proposed method to reduce the peaks and theQ-factor of the resonances.
