The analytical estimates result of changes in the efficiency of the accelerating structure and the accelerating system as a whole with a shift in the operating frequency of the microwave system of a linear electron accelerator with a travelling wave of 10 cm range are presented. In order to verify the obtained estimates, measurements of the energy characteristics of the electron beam were carried out when changing the frequency of the master oscillator at the microwave power source and selecting the natural frequencies of the microwave power compression system resonators of the LUE-200 accelerator at the IREN JINR facility.
