The Superconducting Super Collider (SSC) ion source is required to provide a 30-mA H{sup {minus}} beam at 35 keV with a normalized rms emittance ({var_epsilon}{sub n-rms}) of less than 0.18 {pi} mm-mrad. An rf-driven volume source was chosen for the commissioning of the SSC linear accelerator (Linac). The divergent ion source output beam is matched into the Radio Frequency Quadrupole accelerator (RFQ) by an electrostatic Low Energy Beam Transport (LEBT). The SSC Linac Injector (consisting of ion source, LEBT, and RFQ) is required to provide 25 mA of H{sup {minus}} beam (pulse width of 9.6--48 {mu}s at 10-Hz repetition rate) at 2.5 MeV with transverse normalized rms emittance ({var_epsilon}{sub t-n-rms}) of less than 0.2 {pi} mm-mrad and longitudinal normalized rms emittance ({var_epsilon}1) of less than 0.82*10{sup {minus}6} eV-s. The performance of our rf volume source and initial experimental results from the SSC Injector are discussed.
