Radiation-Induced Conductivity in Kapton-Like Polymers Featuring Conductivity Rising With an Accumulating Dose
We have investigated the radiation-induced conductivity (RIC) in Kapton-like polymers in which it increases with an accumulating dose at large dose rates and long irradiation times. Such a behavior is very useful for spacecraft applications as it allows mitigating the spacecraft charging problems. Also, we studied ordinary polymers whose RIC steadily falls after reaching an initial maximum. To interpret experimental results, we used the semi-empirical Rose–Fowler–Vaisberg model. Numerical and experimental results have been compared with published data.
