This is the review of the current status an ongoing theoretical, simulations and some experimental researches of the novel plasma dynamical devices based on the axialsymmetric cylindrical electrostatic plasma lens (PL) configuration and the fundamental plasma-optical principles of magnetic electron isolation and equipotentialization magnetic field lines. The crossed electric and magnetic fields plasma lens configuration provides us with the attractive and suitable method for establishing stable plasma discharge at lowpressure. Using plasma lens configuration in this way some novel cost-effective, lowmaintenance, high-reliability plasma devices using permanent magnets were developed. In part, it was proposed and created device for ion treatment and deposition of exotic coatings, device for filtering dense plasma flow from micro-droplets, electrostatic plasma lens for focusing and manipulating wide aperture, high-current, low-energy, heavy metal ion plasma flow, and the effective lens was first proposed for manipulating high-current beams of negatively charged particles (negative ions and electrons). Here we mainly describe models and results of theoretical consideration and simulation of the novel generation cylindrical plasma devices.
We describe some experimental investigations of the focusing properties of an electrostatic plasma lens based on the use of permanent magnets instead of conventional current-driven coils. These investigations were performed at the IP NASU (Kiev) and at the LBNL (Berkeley) using moderate energy, high current, broad, heavy ion beams. Computer simulation of physical processes involved for typical experimental conditions was also carried out.
Influence of spherical and momentum aberrations of the electrostatic plasma lens (PL) on the focusing character of the intense ion beam on the target is analyzed. The beam form of a focused beam depending on the noncompensated space charge and finite azimuthal velocity at the PL exit is founded. The minimum focused beam radii are calculated for different system parameters. These radii are shown to depend on the beam particles charge to mass ratio. The radial profile of focused multicharged ion beams having unhomogeneous stepped form was founded out experimentally. This effect is most distinct near PL focus and grows when the PL magnetic field does. Tlus emerge a principle possibility to use the PL for ion charge state analysis.
