The experimental study of the surface current excitation under the influence of a relativistic electron electromagnetic field

摘要

The problem of the surface current excitation in a conductive targets by arelativistic electron electric field as the origin of such radiation mechanismsas diffraction and transition radiation of relativistic electron was consideredin frame of both surface current and pseudo-photon methods. The contradictionbetween these viewpoints in respect to the surface current on the targetdownstream surface necessitated the experimental test of this phenomenon. Thetest performed on electron beam of the 6 MeV microtron showed, that not anysurface current is induced on the target downstream surface under the influenceof a relativistic electron electromagnetic field in contrast to the upstreamsurface. This is important implication for the understanding of the forwardtransition and diffraction radiation nature.
