| Abstract | ||
| In this work firstly, a parallel plat capacitor with thin film of Poly Mathyl Metha Acrylate (PMMA) have been fabricated for different thickness using a spinner technique. Secondly, the effect of gamma ray radiation on electrical properties of these capacitor have been studied. Electrical characteristic of un-exposured and exposured capacitor to gamma ray for different periods times have been studied. The results show that the breakdown voltage, in general, is decreased an exponentially when the capacitor exposured to a certain time of radiation. while it’s reveal an increasing breakdown voltage with the increasing in irradiation period time. This work is also include the study of the effect of radiation on electrical conductivity. The results show that there is an exponentially decreasing in electrical conductivity as increasing exposured time for gamma ray. Finally, the effect of gamma radiation on the value of capacitance for the fabricated capacitor, have been studied. The results show that there is an increasing in it’s value as increasing in exposured time. | ||
