The concentration of N-2 was changed from 2,5% to 20% and the mixtures pressures were varying from 0.05 to 1.8 atm. In Ne-N-2 mixtures, excitation energy of Ne atom can be used to ionize N-2 molecule by the Penning transfer. Comparing the measured and calculated with MAGBOLTZ simulation program gas gains the Penning energy transfer probability and the second Townsend ionization coefficient, beta, describing secondary processes playing a role in avalanche formations have been determined.trinfo:eu-repo/semantics/closedAccessDetector modelling and simulations II (electric fields, charge transport, multiplication and induction, pulse formation, electron emission, etc)Avalanche-induced secondary effectsCharge transport and multiplication in gasElectron multipliers (gas)Argon-isobutane mixturesIonizationNeonInstruments & instrumentationEnergy transferIonization of gasesMixturesAvalanche formationEnergy-transfer probabilityGas gainHigh-precision measurementIonization coefficientSecondary processSimulation programNitrogen compoundsArticle0006082655000042-s2.0-850982798331512Instruments & instrumentationProportional Counters; Gas; Parallel Plates
