Aberrations in electromagnetic plasma lenses proposed for intense large-aperture ion beam focusing
It is shown, that in electromagnetic plasma lenses moment aberrations obey the conservation law of the moment of the ion generalized momentum; they disappear when an ion source is placed in a zero magnetic field. Geometrical aberrations can be removed by choice of the optimal electric field intensit...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | It is shown, that in electromagnetic plasma lenses moment aberrations obey the conservation law of the moment of the ion generalized momentum; they disappear when an ion source is placed in a zero magnetic field. Geometrical aberrations can be removed by choice of the optimal electric field intensity distribution along the radius that have been calculated. As a result, the ion current density and beam compression can achieve in the focus a value up to 10³ A/cm², and 10⁵, accordingly. Then influence of discrete distribution of the external (boundary) electrical potential upon ion focusing was studied, and an example of two-lens achromatic system have been investigated as well. |
