Abstract
A plasma ignition detection device for connecting to an impedance matching circuit for a plasma generation system is configured to process first time-variant measured values from a first predetermined location of the impedance matching circuit. An applied first reactive and/or active power is capable of being determined from the first time-variant measured values. The plasma ignition detection device is further configured to process second time-variant values associated with a second location of the impedance matching circuit, the second location being different to the first predetermined location. An applied second reactive and/or active power is capable of being determined from the second time-variant values. The plasma ignition detection device is further configured to determine a first time-variant variable from the first time-variant measured values, determine a second time-variant variable from the second time-variant values, and generate an output signal describing a plasma state, depending on the first and second time-variant variables.
