The preliminary results show that when the total radiation dose is small (less than 100kGy), the relative permittivity of the capacitor does not change significantly before and after the radiation. When the absorbed dose reaches 1000kGy, the relative permittivity of the capacitor decreases by 5.1×10 -1 %; irradiation will cause the voltage ...
To study the radiation stability of the capacitors, they were irradiated with 1 kGy dose of 5 MeV gamma rays using a linear electron accelerator ELU-4 (Salaspils, Latvia). One kGy is the dose that an electronic device with 1 mm thick aluminium shielding receives in the geosynchronous earth orbit during a 10-year mission [33] .
The first set of experiments evaluated the effects of gamma radiation on capacitance when the devices were irradiated with a dose of 40 kGy, with a second experiment examining whether the internal resistance and self-discharging abilities of the supercapacitors changed before and after being irradiated with a dose of 89 kGy.
