The suggested complex method of the cathodes quality control allows to measure as the form, the middle dimensions and the thickness of the electron emission centers on the cathode surface as the middle dimension between the electron emission centers and the degree of cathode emission activity. The suggested method is based on the mathematical processing of the electron emission voltampere dependences.
