Investigation of the Nonlinear Transformation of an Ion Beam in the Plasma Lens

2011 
The plasma lens can carry out not only sharp focusing of ions beam. At those stages at which the magnetic field is nonlinear, formation of other interesting configurations of beams is possible. Plasma lens provides formation of hollow beams of ions. Application of the several plasma lenses allow to get a conic and a cylindrical beams. The plasma lens can be used for obtaining a beams with homogeneous spatial distribution. Calculations and measurements were performed for a C +6 and Fe +26 beams of 200-300 MeV/a.u.m. energy. The obtained results and analysis are reported.
