The Influence of Parasitic Capacities on Measurements of the Dynamic Behaviour of a Gas Discharge

Measurements of the impedance behaviour of the positive column of a glow discharge are falsified by parasitic capacities. A model, which respects these capacities, was developed and tested by computer simulations and experimental data. Using this model it is possible to correct the influence of parasitic capacities on experimental measured impedance curves. The efficiency of this method is demonstrated on some measurements in a neon discharge.
