相对论粒子通过天然或光子晶体产生的衍射辐射强度的时间依赖性
Time Dependence of the Intensity of Diffracted Radiation Produced by a Relativistic Particle Passing through a Natural or Photonic Crystal
摘要：
本文导出了描述相对论粒子在晶体中运动时产生的辐射随时间演化的公式。它示出的条件下，参数（准切伦科夫）辐射，过渡辐射，衍射辐射的振荡器，表面准切伦科夫和Smith-Purcell辐射持续时间大大长于粒子飞行通过晶体的时间是可实现的。实验结果表明，在电子束离开光子晶体后，会出现附加的辐射峰。
英文摘要：
The formulas which describe the time evolution of radiation produced by a relativistic particle moving in a crystal are derived. It is shown that the conditions are realizable under which parametric (quasi-Cherenkov) radiation, transition radiation, diffracted radiation of the oscillator, surface quasi-Cherenkov and Smith-Purcell radiation last considerably longer than the time of the particle flight through the crystal. The results of carried out experiments demonstrate the presence of additional radiation peak appearing after the electron beam has left the photonic crystal.
