Abstract: This disclosure describes systems, methods, and apparatuses for extinguishing electrical arcs in a plasma processing chamber. Once an arc is detected, the steady state voltage provided to the plasma processing chamber can be reduced, and the current being provided to the chamber decays below a steady state value as the arc is extinguished.

This technique enables power to return to a steady state level faster than traditional arc mitigation techniques.
