| Popis: | A theory was elaborated on transition radiation (TR) from electron bunches that pass through diaphragms of various geometries. At the base of this theory are induced charges and currents in the conductive diaphragms that are generated by electron bunches. An important role of the earth points of diaphragms was proven experimentally and theoretically. A feasibility study was made on controlling the spectra of electromagnetic pulses (EMP) and their directivity patterns. A new configuration for the diaphragms was proposed: twin diaphragms. Calculated and experimentally measured were spectra of such EMPs that were formed by the induced conduction current during the flight of the electron bunch through the twin diaphragms. |
