Coupled simulation of plasma-surface interactions during early stages of vacuum arcing
Roni Koitermaa, Andreas Kyritsakis, Tauno Tiirats +2
We describe fully coupled simulations that bridge atomistic cathode dynamics and plasma formation during the earliest stages of vacuum arcing. The model combines molecular dynamics…

Influence of an external static magnetic field on prebreakdown electron emission and heating
Roni Koitermaa, Marzhan Toktaganova, Andreas Kyritsakis +4
High magnetic fields can increase the occurrence of vacuum arcing, suggesting that both electric and magnetic fields can play a role in the vacuum arcing process. The mechanism of…
