Design and study of an enhanced filament ion source

► We studied different filament ion sources. ► We proposed a method for simulation of the filament ion source performance. ► In addition we introduced a novel filament ion source with higher reliability. ► The simulation shows a considerable improvement in the performance. ► The developed approach allows a proper theoretical method to gain efficient magnetic field in the filament ion source; which can lower the cost and decrease design and fabrication time.
