The influence of residual atmosphere in magnetron to its output parameters

In this paper the results of theoretical and experimental researches of the noise oscillation in the name of magnetrons are presented. The investigation have been carried out for the magnetrons of two types: S-band pulsed magnetron and X-band continuous magnetron. The analysis of residual atmosphere shows the two mechanisms of noise generation to be in the interaction space of these tubes. It is the ion mechanisms and electron mechanisms. For computer modelling of excitation process of intermodulation interferences inside magnetron the 2D code MAGNOL was used. The computer modeling was carried out for the oven magnetron.
