Title:     FEBIAD MK9 Development

Abstract: In order to broaden the range of RIB production at ISAC, a Forced Electron Beam Induced Arc Discharge (FEBIAD) was introduced to ionize elements with high (>5eV) ionization potential. The FEBIAD MK9 is a plasma ion source based on the designs of the MK5 developed at CERN and the FEBIAD at GSI. Since its first use in 2006 for on-line RIB production, the FEBIAD has undergone modifications and improvements mainly for the purpose of increasing its reliability; in particular a water cooled coil has been implemented.  
Recent simulations suggest that the yield could be increased by modifying the plasma electrode shape and the plasma volume. Results of these tests with different configurations will be presented.
