The variation of trap densities in polyimide films with the irradiation dose are investigated by TSC, together with the study of the dielectric property. At 75℃ a TSC peak appears, and the peak position has no obvious relation with the irradiation dose. It is found that the trap densities at each energy depth varies homogeneously with the action of irradiation, and increases exponentially with the absorbed dose. At the same time the dielectric dissipation factor increases with the dose. However, an extraordinary change is seen at the dose of 5×10,6, Gy.
