This talk will describe the ion beam optical design of the Injector for Radioactive Ion Species 2 (IRIS2) at the Holifield Radioactive Ion Beam Facility of Oak Ridge National Laboratory. This will include descriptions of the ion source extraction system, 40-keV beam line with 1st-stage mass separator, and 200-keV beam line with high-resolution mass separator.
Commissioning results with both stable and radioactive beams will be presented.
