ABSTRAKT
In this work the authors continue their investigation of a millimeter wave weakly relativistic pulse magnetron [1,2], aimed at the optimization of electric parameters of the device and pointing out the disturbing factors in its efficient performance. The research is illustrated by experimental results featuring the excitation conditions of an 8-mm relativistic magnetron consisting of 48 resonators (RM8). The experiment sought to define oscillations frequency and modes and to obtain numerical values of the relations between the generation intensity and the magnitudes of the external static E- and H-fields. It was revealed that, over a wide value range of the external fields, the π-mode is the principal oscillation mode of the frequency range under study (37...41 GHz). The paper also reports the results of optimizing the operation modes of generation (pulse high-voltage U0 and external magnetic field induction B0) and their dependence on the geometric parameters of magnetron interaction space, namely on cathode dimension and the cathode-to-anode distance dca.
