The plasma lens can carry out sharp focusing of ion beam with considerable reduction sizes of focal spot. At those stages of the plasma discharge at which the magnetic field is nonlinear, formation of other interesting configurations of beams is possible. The report presents the results of studies transformation the Gaussian beam into hollow one and into beam with homogeneous spatial distribution. The discharge current distributions obtained by numerical calculation ensure the experimental beam transformations. Thus possibility of the research of the plasma discharge dynamics by means of relativistic ions beams is shown. The plasma lens represents the universal device for scientific and technical applications in particular for irradiation of medical objects.
