Method of potential optimization in magnetoelectrostatic plasma lenses
In magnetoelectrostatic plasma lenses the strength and spatial distribution of the magnetic and electric fields were optimized for maximum beam current density in the focal plane. Experimental implementation of the optimization is difficult because it is necessary to control the electric field stren...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | In magnetoelectrostatic plasma lenses the strength and spatial distribution of the magnetic and electric fields were optimized for maximum beam current density in the focal plane. Experimental implementation of the optimization is difficult because it is necessary to control the electric field strength within the lens volume by measuring the electric field in the plasma with sufficiently high precision. Here with the help of the computer model, it is proposed and tested the method of determining optimum potential distribution on the reference electrodes, by sequential increasing of a focused ion beam radius from zero to maximum value determined by the lens aperture. |
