Circumscribed are electron-optical systems (EOS) with a back electrode, in which a height of a back electrode h exceeds Larmor diameter DL of an electron orbit above the emitter (h > DL) noticeably. Given are the basic results of model operation for the relevant EOS on a dynamic mock-up in view of secondary emission. It is shown that the pre-sence of a back electrode in forming systems gives in diminution of influence of secondary emission on parameters of beams of all types.
