THE TRANSVERSAL BEAM EMITTANCE CHANGE AFTER THE PASSAGE OF ION BEAMS THROUGH THE DIPOLE MAGNETIC FIELD

Jn Jank - Michael Mller

   The change of the phase space beam ellipse area xx' occupied by ions of a beam with a momentum dp/p in the presence of a transversal magnetic field is studied. A consequence of this is an increase of the transversal beam emittance. Quantitative aspects of this effect are applied to the beam from a PIG ion source. By this effect the different values of beam emittances measured in xx' and yy' phase areas should be explained. Analysis and numerical calculation of emittance regarding this effect were made.

Keywords: PIG ion source, beam emittance, ion beam optics, ion beams, ion source, beam transport
