The ISOL facility TRIUMF-ISAC utilizes a number of different ion sources to produce radioactive ion beams. Most isotopes are ionized using surface or resonant laser ionization, but these techniques are prohibitively inefficient for species with high ionization energies, such as noble gases and molecules. For these cases, the Forced Electron Beam Induced Arc Discharge (FEBIAD) ion source can be used. The FEBIAD uses a hot cathode to produce electrons, which are accelerated through a potential (< 200 V) into the anode volume. Isotopes entering the resulting plasma undergo impact ionization and are extracted. Efforts are under way to better understand the physics and operation of the FEBIAD, using both theory and experiment. Recent measurements and simulations on the ISAC FEBIAD will be reported here.
