Abstract
We have measured the replacement correction factors (Prepl) for a PTW/Markus parallel plate chamber at mean incident electron energies of 3.1, 4.4, 8.9, 13.0, 16.3, and 18.8 MeV. The factors are significantly different from unity at low energies.
摘要
我们已测量了PTW/马库斯平行板电离室在平均入射电子能量为3.1、4.4、8.9、13.0、16.3和18.8兆电子伏时的替换校正因子（Prepl）。这些因子在低能量时与1有显著差异。
