摘要
本文介绍了用质子束激发靶元素发射特征线的方法建立的高强度、准单色低能X光源的主要特征、物理性能及其实际应用。当K-400加速器提供的质子流指标为1mA/270keV时,在0.183-3keV之间的9个能点上,其相应源强可达10^(10)-10^(13)个/s数量级,为低能X光诊断技术的发展提供了必要条件。
In this paper the principle, structure, performance and application of a fluorescent radiation source excited by protons are described. When the K-400 proton accelerator provides a proton beam of 1mA at 270kV, the source intensities at nine energy points between 183eV and 3OOOeV are about 10^(10)～10^(13) photons/sec. The source has been employed to develop diagnostic techniques for low energy x rays.
