Vacuum arcs have been studied for over a century due to their relevance in high-voltage engineering, accelerator science, and power switching. In applications such as muon colliders and vacuum interrupters, magnetic fields are present and may influence the early stages of plasma formation in vacuum arcs. In this study, we explore electron trajectories during the ignition phase of a vacuum arc...
Vacuum tube-based RF sources, such as those used in linear accelerators, plasma heating systems, and advanced imaging applications, critically depend on the performance of electron emitters—particularly with respect to longevity, efficiency, and reliability. Field emitter (FE) technologies offer several advantages that make them especially suitable for these high-frequency devices: they...
The vacuum electrical breakdown (BD) or vacuum arcing happens when a conducting plasma arc forms in vacuum between electrodes under high voltage. For decades, researchers have studied this phenomenon through experiments, theories, and computational models, focusing on different material properties affected by this process.
Generally, one of the material's property that seems related to this...
Delayed breakdown in high-current vacuum interruption has emerged as a critical technical challenge restricting the development of high-voltage vacuum interrupters (HVIs). This study focuses on the origin and motion characteristics of metal particles during the post-arc phase, aiming to investigate their potential role as triggers of delayed breakdown. An optical diagnostic platform...
As interest in SF6-free technologies increases, the demand for vacuum interrupters (VIs) capable of operating at higher voltage levels is also growing. To meet these demands, design innovations such as larger contact gaps and the series connection of multiple VIs have been implemented.
During the current interruption process, a high plasma density forms between the electrodes. Once the...
