ANALYSIS OF UNCERTAINTY OF DOSE RATE MEASUREMENT ON THE ACCELERATOR 'QIANG GUANG-I'

摘要

"QiangGuang-I", working at short pulse state, can be used to research the transient radiation effects on electronic devices. The measurement of dose rate is significant for assessing devices' radiation-resistant ability. This paper comprehensively analyzes the originations of uncertainty on dose rate's measurement, such as thermoluminescent dosemeter's linearity degree and response to X-rays energy spectrum, testing instruments' resolution, waveforms' transmission distortion, and positional error; figures out the extended uncertainty. The result shows that the extended uncertainty of dose rate's measurement is less than 20%, which is satisfactory for researching on devices' transient radiation effects, and proves that the method used to measure dose rate is reasonable.
