We describe a dc volume H/sup -/ source, employing multicusp plasma confinement, which has been constructed for use with the TRIUMF cyclotron. An extracted H/sup -/ current density of 12 mA/cm/sup 2/ has been obtained. Beam emittance and brightness have been measured as a function of current density and beam fraction. Beam brightness values for normalized beam emittances of the order of 0.2 ..pi..mm mrad at 81% beam fraction are typically 10 mA/(mm mrad)/sup 2/ (equivalent rms B = 223 mA/(mm mrad)/sup 2/).
