This paper investigates the charge accumulation behavior of proton irradiated fluorinated insulating materials by applying a DC voltage to the materials and measuring the space charge distribution. In addition, the electronic energy levels were calculated using the quantum chemical calculation, and the external circuit current density was measured to examine the charge accumulation behavior. The results showed that proton irradiation lowers the charge injection barrier and changes the conductivity distribution in the sample. The charge accumulation distribution was changed by those phenomena. Furthermore, it was found that changes in charge accumulation characteristics caused by proton irradiation continue for a long time.
