FIELD: microwave electronics.
SUBSTANCE: creating magnetic periodic focusing systems (MPFS) for focusing an electron beam in vacuum electronic devices. When manufacturing MPFS, all magnets have a strictly limited level of the transverse component, and adjacent magnets have a limitation on the difference in the value of the transverse component of magnetic induction, not exceeding 0 to 15-50% of the maximum allowable value; the exact value of the allowable difference is selected depending on the type of MPFS and electronic device. This ratio allows to provide the necessary compensation for the effect of the transverse component of the magnetic induction on the electron beam in a small area of the device.
EFFECT: reduced labour intensity and a significantly reduced setting time of the electrovacuum device.
