An Interpretation of a Radiation Damage Phenomenon of the Solar-ACCD

High-energy radiation exists in the space natural radiation environment may cause the deg radation of the performance of charge-coupled-devices used in space.The Solar-A satellite was launched in 1991.Since then, radiation damage effected phenomena have been reported.The flatband voltage shift resulted from the trapped holes within the insulator layer between the CCD gates and bulk silicon may throw light on the interpretation of some of the radiation damage phenomena..
