Depression coefficients for a cylindrical electron beam with three and four of variable component variations of current density on an azimuth

Depression coefficients for a cylindrical electron beam with different number of variable component variations of current density on an azimuth are computed. The results obtained are compared with depression coefficient for a cylindrical electron beam with axially symmetric distribution of a current density. It is shown, that these last ones by over a factor of ten exceed depression coefficients with three and four variations of a current density at equal parameters of an electron beam.
