Abstract. During klystron development it is necessary to take into account fundamental limitations associated with the growing influence of  space charge forces preventing  formation of denser electron bunches. We believe that the refuse of the model of one-dimensional motion of electron beam and the use of a new principle of formation of 3D grouping of electrons in an inhomogeneous magnetic field  without initial  longitudinal electron velocity modulation will help to avoid these limitations.

Key words: electron beam, grouping, space charge.
