Relativistic millimeter-range microwave amplifier using a high-current electron miniaccelerator
Abstract
A relativistic Cerenkov 8-mm microwave amplifier with a maximum output power of 1 MW was developed using a high-current electron miniaccelerator. The experiments involved the study of a TWT in which an intense electron beam with an electron energy of 200 keV and a current of 0.6 A is synchronized with the positive first spatial harmonic of the HE(11) wave of a circular corrugated waveguide. The maximum output power was achieved at a gain of 22 dB and a pulse length of about 1.5 ns.
