A study of anode and secondary emission cathode surface of three-millimeter and eight-millimeter magnetrons was performed using the scanning electron microscope and the electron probe X-ray microanalysis after long life tests. Heterogeneous distribution of surface erosion and altering of surface composition were discovered. Possible mechanisms causing the discovered changes are described. The obtained results are important for solving of the essential problem of increasing of reliability and repeatability level of the devices applied at the most advanced microwave systems.
