摘要：

A scheme for automatic measurement of current-voltage characteristic of gyroresonance devices has been developed. Efficient emission inhomogeneity of cathode in powerful gyrotrons has been studied basing on analysis of current-voltage characteristics. Experimental data on the parameter of efficient emission inhomogeneity for different regimes are presented, as well as the estimate for admissible efficient inhomogeneity of the cathode for powerful gyrotrons and the dependence of electron beam parameters on efficient inhomogeneity of the cathode. A method of complex measurements is proposed, which makes it possible to judge about the contribution of different physical mechanisms into emission inhomogeneity of the cathode.
