    “…Breakdown localisation is an important diagnostic for studies of vacuum arcs in high electromagnetic field systems such as DC electrodes and radio frequency (RF) accelerating structures. For example, determining the position of individual breakdowns and corresponding distributions of ensembles of breakdowns are important measurements in high-gradient X-band test stands (CERN, SLAC, KEK) where these measurements are made by monitoring the RF signals.A highly precise breakdown localisation technique has been developed for the CLIC (Compact LInear Collider) pulsed DC electrode systems. …”
