Description
The demand for extracted beams from TRIUMF's 500 MeV cyclotron is growing with the addition of ARIEL, its new advanced rare isotope beam facility. To meet these intensity requirements, an upgrade program has been initiated for the injection system. The program involves installing a new injection beamline and an additional ion source to enable high-brightness, intense beam injection. Commissioning of the new beamline is complete, and integration of the additional ion source is in progress. The existing ion source had critical limitations: initial beam energy was capped at 12 keV, and filament power at 2.5 kW, resulting in short filament lifetimes. A new source will be developed to produce a high-brightness $25~\rm{keV}~\rm{H}^{-}$ beam with significantly extended filament lifetime. A specialized transport system uses magnetic optics to maintain space-charge neutralization. The status of this upgrade program will be presented.
