The ignition and control condition for the useful discharge in a GlidArc reactor with plane geometry and auxiliary electrodes

The paper refers to the optimal operation of GlidArc type cold plasma plane-symmetrical electrochemical reactors with auxiliary electrodes and proposes the correct definition for the position of the auxiliary electrodes when designing the device. This proposes considering the capacities that characterize the ignition and distribution of the pilot electrical discharge between the E1 - A1 - A2 - E2 electrodes and defines the analytical optimal operation condition for the device, leading to an irrational equation having the position of the auxiliary electrodes as solution. Highly correlated with experimental observations, it is found that one or two positions of the auxiliary electrodes can be defined for the convenient evolution of the auxiliary discharge, allowing the command and control of the main electrical discharge in a GlidArc reactor.
