Abstract

Accordingtothecharacteristicsoftransientplasmaejectorscreatedbyhypervelocityimpact, thesweepLangmuirprobe,thetripleLangmuirprobeandthecoilmeasurementsystemswere establishedtomeasuretheplasmacharacteristicparametersaswellasthemagneticinductionintensity inexpandingplasmacloud.Basedonthegivenlayoutandazimuthangleofthesensors,theelectromagneticcharacteristicmeasurementsofexpandingplasmacloudgeneratedbytheimpactof2024- T4 aluminumprojectilesagainstthe2024-T4aluminumtargetsinthelaboratorywerecarriedoutatthe twoimpactvelocities.Experimentalresultsshowthattheaverageelectrontemperature,electrondensity, andmagneticinductionintensityamplitudevalueare0.4~0.9eV,ontheorderof1012cm-3and 10~20nT,respectively.Byprocessingtheexperimentaldata,therelationshipsbetweenelectron temperature,electrondensityand magneticinductionintensitywereobtained,respectively,atthe givenpositionsoftheprobesandcoilsduringthewholephysicalprocessforthetwoexperiments.And theresultsmeasuredbythesweepLangmuirprobeandthetripleLangmuirprobewerecompared.
