| Abstract: | A new technique is proposed to simulate proton irradiation using plasma sheath acceleration.The hydrogen ions(H+)are produced in a vacuum chamber by inductance-coupled radio-frequency discharge.A high negative voltage is applied to samples on the target holder to produce H+ ion irradiation.The optical transmissivity,surface morphology,and chemical structure of Polyimide(Kapton) samples are determined by UV-VIS-NIR scanning spectrophotometer,AFM and XPS analyses,respectively.The results show that the transmi... |
