This paper addresses the new development of high power RF Klystron - like amplifiers using modulated intense relativistic electron beams. This research followed an earlier work in which the interaction between a high impedance ( 120 ohm) intense relativistic electron beam and a low power RF pulse resulted in the generation of coherent bunches of electrons with excellent amplitude and phase stabilities. In the present experiment a low impedance (30 Ohm) large diameter ( 14 cm ) annular electron beam of power ~ 8 gigawatts was modulated using an external RF source (Magnetron) of 0.5 megawatt power. The sequential interaction of the modulated electron beam with a structure generated a 3-gigawatt RF pulse that was radiated into the atmosphere.
