In the present work, concentration and pressure dependence of Penning transfer rate and photon feedback parameter in Ar-CO2 mixtures have been investigated with recent systematic high-precision gas gain measurements which cover the range 1-50% CO2 at 400, 800, 1200, 1800 hPa and gas gain from 1 to 5 x 10(5).eninfo:eu-repo/semantics/openAccessGas detectorsPenning transferExcited statesPhoton feedbackElectron-drift velocityArgonAmplificationIonizationDischargeInstruments & instrumentationNuclear science & technologyPhysicsCarbon dioxideEnergy transferIonization of gasesMixturesPhotonsEnergy transfer measurementFeedback parametersGas gainHigh-precisionPenning mixturesPressure dependenceTransfer ratesGasesArticle0003449954000162-s2.0-84908042595104111768Instruments & instrumentationNuclear science & technologyPhysics, nuclearPhysics, particles & fieldsProportional Counters; Gas; Parallel Plates
