Description
Systematic gas gain measurements in Ne-CO2 mixtures at different pressures with varying CO2 concentrations are used to obtain the rates of the excitation induced ionisations (Penning energy transfer probabilities). Over-exponential increases on the gain curves, due to the secondary processes in avalanche development have been investigated with an effective parameter. Calculations for the pure CO2 mixtures confirms that Magboltz use perfectly correct cross sections. The production frequencies of the direct ionisations refers that the largest part of the gain comes from CO2 ionisations. Three-body energy losses of excited Ne atoms can be a reason of the energy transfer drops observed at high CO2 percentages.
