Abstract: WithsatellitepayloadRFpowerincreasing,traditionalmethodsof inhibitingmultipactorareunabletomeettheneedsofhighpowersatellitepayloads.Reducingthe secondaryelectronemissioncoefficientofinternalsurfaceofhighpowerRFcomponentsisanimpor tantmethodforinhibitingmutipactor.Nanoscalesilvertrappingstructurewaspreparedbyconstructing nanodimensionZnOarrays,  andtheeffectsofpreparingmethodsofseedsandzincsaltconcentration onthegrowthofZnOarrayswerestudied.TheresultsshowthathomogeneousZnOarraysareobtain edonthesamplesurfacebyusingtheUVradiationforseedssynthesizationandincreasingzincsaltconcentration.TheeffectofpackingdensityofZnOarraysonsilverfilmsconstructionwasinvest igated.ItshowsthatlowdensityZnOarraysaresuitablefordepositionofsilveronthesurface ofZnOnanorods.Therefore,  thetechnologyforpreparationoftrapstructuresilverbasedonZnOarray swasobtained,andthemaximumsecondaryelectronemissioncoefficientofsilverdecreasedby36.3% .
