相对论电子电磁场作用下表面电流激发的实验研究
The experimental study of the surface current excitation under the influence of a relativistic electron electromagnetic field
摘要：
在表面电流和赝光子方法的框架下，考虑了相对论电子电场在导电靶中激发的表面电流问题，并将其作为相对论电子衍射和跃迁辐射等辐射机制的起源。这些观点之间的矛盾，在目标下游表面上的表面电流有必要对这种现象进行实验测试。对6 MeV电子束进行的测试表明，与上游表面相比，在相对论电子电磁场的影响下，在靶下游表面上没有感应出任何表面电流。这对理解前向跃迁和衍射辐射的本质具有重要意义。
英文摘要：
The problem of the surface current excitation in a conductive targets by a relativistic electron electric field as the origin of such radiation mechanisms as diffraction and transition radiation of relativistic electron was considered in frame of both surface current and pseudo-photon methods. The contradiction between these viewpoints in respect to the surface current on the target downstream surface necessitated the experimental test of this phenomenon. The test performed on electron beam of the 6 MeV microtron showed, that not any surface current is induced on the target downstream surface under the influence of a relativistic electron electromagnetic field in contrast to the upstream surface. This is important implication for the understanding of the forward transition and diffraction radiation nature.
