Identifying high power breakdowns in accelerating structures with acoustic sensors

Abstract

To increase the energy of Particle Accelarators to reach the requirements of the Linear Collider or of the Super KEK-B factory, new accelerating structures with a higher accelerating gradient need to be developped. These accelerating structures are often affected by high power breakdowns. Knowing the exact location where these breakdowns occured helps to redesign the structure and improve its performances. This can be done with acoustic sensors.
