| Summary: | We describe the development of the plasma lens with dynamic positive space charge for manipulating and focusing
intense beams of negative charge particles. Floating potential spatial distributions in lens with modified magnetic field
are investigated. It is shown that magnitude of magnetic field at the lens cloud area doesn’t impact essentially on
floating potential distributions. Interrelation between the value of floating potential maximum and anode potential value
is demonstrated experimentally. With anode potential growing the efficiency of space charge creation decreases and the
electric field magnitude depends weakly upon anode potential at given pressure in the lens. |
