Abstract:
When focusing light ions with intense light ion-beam diodes, problems occur with ions emitted at the edge of the anode plasma. Numerical studies investigating this well-known experimental observation are presented. Going beyond the computational simulations introduced by Westermann (1991 Appl. Phys. Lett . 58, 696), two suggestions for the case of the self-magnetically B θ -insulated ion diode are presented to focus the beamlets emitted from outer parts of the anode. The first one is based upon the idea of changing nonemitting parts of the anode surface and the second one of shifting the emitting anode surface into the anode body.
