Possibility of broadening continuous electrical frequency tuning in mm-wavelength clinotron: Experimental investigation

In this paper, possibilities of the extension of the continuous frequency tuning bandwidth in the clinotron operating frequency range are studied. The most attractive approach is optimization of the geometry of the slow-wave oscillatory system of the tube. It is shown that by means of the distance variation between the slow-wave structure and the opposite cavity wall it is possible to provide the continuous frequency tuning bandwidth up to (20...25)%.
