In paper presented results of the calculation of microwave and magnetic systems X-band microtron. Microwave system is expected to run for the base monoblock monoblock magnetron-accelerating cavity. The results of the analysis of stationary processes and transients in such system are presented. The requirements to parameters of coupling element in of the magnetron's anode block with accelerating cavity are determined. The calculations of magnetic system for 5 MeV X-band microtron on the base permanent magnets are executed.
