The number of primary electrons and ions in the conversion gap were calculated using the FLUKA code for incoming electrons. The signal resolution is a function of the energy loss or the number of produced primary electrons and its fluctuation in the detector volume. The signal generations were made with a Single Particle Monte Carlo simulation technique in the amplification gap region. We assumed a homogeneous electric field inside both the conversion and the amplification gap because the electric field shows only a small change near the openings of the microgrid. Based on the simulation, we discuss the signal fluctuations that affect the work performance of the Micromegas for different argon-based gas mixtures.eninfo:eu-repo/semantics/closedAccessEngineeringInstruments & instrumentationElectric fieldsEnergy dissipationMonte Carlo methodsSignal generatorsAmplification gapFLUKA codesGaseous detectorsHomogeneous electric fieldMicro gridMicromegasMonte carlo simulation techniquePrimary electronsSignal fluctuationsSignal generationSignal resolutionSignal valueSingle particleWork performanceGas mixturesArticle0003092332000042-s2.0-84870479275542544555Engineering, multidisciplinaryInstruments & instrumentationProportional Counters; Avalanches; Parallel Plates
