Abstract :
Summary form only given, as follows. Presents the theoretical investigations of the plasma lens for high-energy ion-beam focusing. The authors propose a new scheme of the focusing effect obtained due to longitudinal polarization in a plasma motion through the magnetic field of a short coil. Electrons of a plasma flow from a plasma gun when coming upon the magnetic barrier are slowing faster compared to the ions. The estimation of the plasma density, magnetic field etc. are performed for obtaining a plasma lens with focusing length of 15 cm for focusing of a proton beam of 5 MeV energy and 30 mA current.
