Abstract
The proposed ion optics extraction geometry from ARIEL has been optimized
based on simulations with Comsol. Geometrical parameters such as the acceleration
gap and angle of the face of the vacuum chamber were studied in order to improve
the beam 4-emittance and beam spot size. For geometries of interest, additional
studies have been performed: voltage dependence, mass dependence, and the effect of
the ion source misalignment on the beam parameters and how to compensate them.
Simulations and experimental measurements were also performed for the current ISAC
surface ion source to corroborate the simulation results.
