Abstract: A multiple parallel plate Aluminum ionization chamber has been designed.Using the ionization chamber the measurement dose gradient distribution at and near the interface of Kovar/Au/Al,Pb/Al,Ta/Al has been done for 30—100keV Beijing synchrotron radiation facility x-rays and DEF(Dose Enhancement Factor)are provided.Complementary metal-oxide semiconductor (CMOS) 4069 devices are irradiated by hard x-rays in BSRF with emphasis on the relative dose-enhancement factor.Using Bi-laminate structure,the equivalent relation of total dose damage is setup by comparing the response of devices,damage enhancement factor of the device is provided.These methods are provided for X-rays radiation hardening technology as an effective evaluation approach.
