MUCIS is one of the first high current gaseous ion sources used at GSI for beamtime operation. It is a filament driven ion source with non-axial filament configuration. It has two filament holders which are equipped with 3 spiral tantalum filaments and placed symmetrically relatively to the beam axis. The multi-cusp field is realized by 60 SmCo-magnets (1.8 Tesla). In addition one can apply a confining field of up to 0.1 Tesla with an external magnetic coil. MUCIS is universal source for production of all types of gaseous ions (light and heavy gases).
