D-Pace’s TRIUMF-licensed multicusp filament ion source is capable of producing H⁻ beams up to 17.4 mA*. In most cases, the H⁻ beam is transported to the entrance of an accelerator or a magnet for further applications. The emittance of the beam extracted from the ion source should be maintained as low as possible to reduce the beam losses to the walls of the transport pipes. The beam emittance from the ion source can be controlled by changing the aperture diameter of the plasma electrode. The current study deals with the range of H⁻ beam emittance that can be achieved from D-Pace’s filament ion source, using different plasma electrode aperture sizes. The corresponding beam currents and the electron to ion ratios are also reported.
