Beam emittance of the high current ion sources at GSI
In order to compare the beam quality produced by the ion source CHORDIS and the Vacuum arc ion source VARIS, beam emittance measurements have been performed. The ion sources were equipped with a multi-aperture accel-decel extraction system, which is usually chosen for beam time operation. A slit-grid emittance measurement device was used for these investigations. Computer simulations with the KOBRA3 INP code supplement the measurement. more...
