Introduction
International workshop on Mechanisms of Vacuum Arcs (MeVArc)
The mysterious nature of vacuum electrical breakdown at high electric fields grows more obscure with increasing the quality of vacuum to an ultrahigh level. Although the rate of sparks can be measured, the sparks themselves have rather stochastic nature. Many efforts have been devoted to find a consistent and self-explicable picture of a trigger of electrical breakdown aiming to have a deep understanding of ongoing processes preceding the actual event. Disclosure of the main reason responsible for an electrical breakdown is a fascinating challenge for Material Science. If the origin of arcing is found, many still unclear features of vacuum plasma in general will be much better understood. Moreover, the lack of systematic studies of the phenomenon suppresses new applications, where a high field is applied in a low-dimensional device.
