WAVE-OPTICAL PROPERTIES OF SYNCHROTRON-RADIATION

Wave properties of synchrotron radiation (SR) emitted in a bending mag net are analyzed. Starting from exact solutions of the Maxwell equatio ns for the electromagnetic field of the particle in motion, precise an alytic expression for the SR phase distribution has been obtained. Thi s distribution is compared with the phase distribution of radiation em itted by a point source, being at rest in the laboratory frame. Strict ly speaking, the SR phase distribution over the entire area cannot pre cisely coincide with that of an immobile point source. Nevertheless, t he carried-out calculations showed that they practically coincide with in a rather large entrance window area. The theoretical results obtain ed will allow to accurately describe the SR wave properties. In partic ular, they may find applications in the SR diagnostics.
