Abstract
The results of a study on electron-beam-induced conductivity in a comm ercial polyimide and Kapton N film (at a dose rate above 100 Gy/s) are reported. It is found that the radiation-induced conductivity (RC) is caused by both the free-ion generation mechanism and by the additiona l conductance component determined by the formation of the metastable microscopic inhomogeneous polyconjugated structures. It is observed th at the process is accompanied by the superlinear voltage-current chara cteristics both during and after irradiation, the strong RC dependence on the absorbed radiation dose, and other phenomena.
