heal.abstract	We present the results on the deformation of the cross section of an electron beam in a cylindrical beam tunnel with partial derivative/partial derivativez = 0 and homogeneus magnetic field, due to azimuthally nonuniform current density distribution. For this purpose, a new three-dimensional, self-consistent, trajectory code has been used. In addition, a simple theoretical model has been seen to be adequate for the qualitative and quantitative interpretation of the numerical results. It has been found, that the azimuthal nouniformity causes effects clearly associated with E x B drifts, but in absolute terms these effects are too small to affect the performance of a gyrotron.	en
