Abstract: AnH-modeionizationsystemwasdesignedfortherequirementsoflowpowerconsumptionandlowelectromagneticinterferenceofthepassivespacebornehydrogenmaser,whichadoptingaplanarrolledcoilantennatosupplypower.Andamathematicmodelofionizationwasbuilt.Firstly,thedistributionmodelofelectromagneticfieldintheionizationbubbleandtheionizationmechanismofthecertainmethodwerededucedfromtheMaxwellequations.Andthen,theionizationpunctureconditioncriterionanditsmathematicmodelwereacquired.Finally,parametersofionizationdevicewereoptimizedbythecriterionequation.Bothsimulationandmeasurementshowthattheionizationmodeliseffective,andtheoptimizeddesignparametershaveimprovedtheperformanceofpowerconsumptionandelectromagneticinterference,andthetotalDCpowercanbelessthan2W.
