Abstract :
Summary form only given, as follows. The excitation of a TEM-horn antenna by a pulsed intense relativistic electron beam (IREB) has been explored for powerful electromagnetic irradiation. Similar investigations for coaxial geometry have already been carried out. In the present work the parameters of the IREB were varied in the following range: energy 500-700 keV, current 3.5 k/spl cong/, time duration 15 ns, risetime did not exceed 1.5 ns. It was observed, that the radiation signal of the antenna contained three various components caused by, respectively: transient radiation of the IREB front, high-voltage oscillating discharge between plates of TEM-horn antenna, and, response due to resonant properties of the antenna device.
