Description

The ion source and injection system beamline is used to transport the $300$keV ${\mathrm{H}}^{-}$ beam from the ion source to the injection point of the $500$MeV cyclotron at TRIUMF. A new ion beam transport system has been designed to transport a highly intense and bright beam extracted from the ${\mathrm{H}}^{-}$ ion source. This new system will be installed at the new injection terminal for TRIUMF's $500$MeV cyclotron. The low energy part of the transport section ($25$keV) in the injection terminal has been designed with magnetic optical elements in order to maintain space-charge neutralization. The injection terminal includes a permanent magnet solenoid lens, magnetic steerers, a pulser, a beam dump, and a $300$kV accelerator column with electron and positive ion suppressor rings. Beam optics calculations have been performed, including space-charge effects up to $1$mA. The simulation results of the beam optics design and the initial beam emittance measurements for the prototype beam transport system will be presented.
