摘要
参量X射线辐射(Parametric X-ray radiation,PXR)是带电粒子虚光子通过晶体受到晶格衍射按Bragg或Laue方式形成的X射线。PXR是准单色光、方向性强、能谱窄、光子/电子转换效率高、波长可调的极化束。电子能量范围:MeV^GeV,具有多方面应用的潜力。
When virtual photons produced by charged particles passes crystal and are diffracted by crystal lattice in the mode of Bragg or Laue geometry, they can form a kind of X-ray radiation named parametric X-ray radia- tion（PXR）, PXR has a serious of characters： linearly polarized, quasi monochromatic, smoothly tunable, narrow width of energy, high efficiency of photo/electron conversion. Electrons in MeV and GeV energies can be used to produce PXR. There are also some aspects of potential application about PXR.
