摘要

在热核聚变研究和等离子体诊断测量中，需要高通量率x射线剂量的绝对测量。设计了一种在高通量x射线下可再现空气-kerma的电离室，并在北京同步辐射装置上对(6-20)keV单能x射线进行了绝对测量。实验得到了自由空气电离室的空气衰减系数和复合校正系数。因此，可以确定$(6 \sim 20)$ keV单能x射线的空气-kerma。

Measurement of air attenuation and recombination correction factors in synchrotron radiation X-rays

Absolute measurement of high fluence rate X-ray dose was required in thermonuclear fusion research and plasma diagnostic measurement. An ionization chamber used for the reproducibility of air-kerma in high fluence rate X-rays was designed, and the monoenergetic X-rays of (6-20) keV were absolutely measured on Beijing Synchrotron Radiation Facility. The air attenuation and recombination correction factors of the free-air ionization chamber were obtained experimentally. Thus, the air-kerma for the $(6 \sim 20)$ keV monoenergetic X-rays can be determined.
