Distribution and Optical Properties of the Pulsed Plasma Thruster Plume Deposition
In order to study the characteristics of Pulsed Plasma Thruster plume contamination,the distribution and optical properties of the films deposited by Pulsed Plasma Thruster were studied.The morphology of the deposited film was analyzed by scanning electron microscopy and scanning probe microscope,transmittance and reflectance of the films were tested using UV-vis spectrophotometers.The results showed that,plasma sputtering and neutral large particles deposition existed in the PPT plume disposition process,the deposited films had strong ultraviolet absorption and enhanced reflective properties.Different plasma characteristics in different region of the PPT plume led to different surface morphology and optical characteristics and trends.
