Abstract
A multiple parallel plate aluminum ionization chamber has been designed for the study of dose distribution at and near the interface of different mate rials. The measurement of dose gradient distribution at and near the interf ace of Kovar/Au/Al, Pb/Al,Ta/ Al has been done for 30-100 keV X-rays from t he synchrotron radiation source, and the dose enhancement factor(DEF) are a lso provided. DEF for interface of different materials is calculated by Mon te-Carlo simulation of particle transportation, and the results are consist ent with the measured dose-enhancement factor. A reliable evaluation approa ch of theoritival and experimental method is proposed for studying X-ray do se enhancement.
