Use of axially symmetric electrostatic fields for ion-beam focussing

Description

The 1/r electric field obtained between charged coaxial cylindrical electrodes is useful for focusing hollow ion beams in ion-microprobe and ion- implantation applications. The focusing strengths are mass-independent at nonrelativistic energies. Focused-particle densities can be enhanced by using a diverging-converging pair to flatten the dependence of focal length on incoming-beam radius. Transport of 425-keV and 1-MeV protons has been simulated and results are presented
