On the problem of forming fields synthesis of SHF devices with partial screening by cathode from magnetic field

For analytically given bending of electron beam with axial symmetry and axial distribution of induction of magnetic field received differential equation, a calculation of a potential on the border of electron beam under known average density of current of cathode is described. The paper considered the possibility of using a received equation for deciding the number of problems and brought the same results in its numerical integration.
