Vacuum arcs are relevant in many engineering disciplines, but the physics behind them is not yet fully understood. In recent years, there have been many experimental and computational studies focused on understanding aspects of vacuum arcs. This thesis focuses on further development of a simulation model to describe the physical processes starting from electron emission and leading...
