Zusammenfassung:	For responding to an arc discharge in a plasma process (PP), a parameter of the plasma process is monitored to detect arc discharges occurring in the plasma. After detection of an arc discharge, a first countermeasure for the suppression of arc discharges is executed. After completion of the first countermeasure, a delay time period is allowed to elapse before the parameter is rechecked. In the event that after conclusion of the variable delay time period an arc discharge is detected, a second countermeasure for the suppression of arc discharges is executed.
