Ap­pli­ca­tion of a plas­ma lens to fo­cus­ing of ion beams has a num­ber of es­sen­tial ad­van­tages. It is im­por­tant that the fo­cus­ing ca­pa­bil­i­ties of the lens de­pend on the stage of plas­ma de­vel­op­ment. Under cer­tain con­di­tions a mag­net­ic field is lin­ear, that allow to focus the beam to a very small spot. In other con­di­tions, the mag­net­ic field is non­lin­ear, that allow for­ma­tion of hol­low and other beam struc­tures. Hol­low cylin­der-shaped beams of high en­er­get­ic heavy ions are ef­fi­cient drivers for im­plo­sion tar­gets to cre­ate mat­ter in a high­ly com­pressed state. The work deals with the study the pos­si­bil­i­ty of using a plas­ma lens to trans­for­ma­tion the den­si­ty dis­tri­bu­tion of ions in the beam. Cal­cu­la­tions and mea­sure­ments were per­formed for a C⁶⁺ and Fe²⁶⁺ beams of 200 MeV/a.u.m. en­er­gy. The ob­tained re­sults and anal­y­sis are re­port­ed.
