The technical challenge for making two-beam accelerators into realizable power sources for high-energy colliders lie in the creation of the drive beam and in its propagation over long distances through multiple extraction sections. This year we have constructed a 1.2-kA, 1-MeV, electron induction injector for the RTA accelerator. The electron source will be a 8.9 cm diameter, thermionic, flat-surface cathode with a maximum shroud field stress of approximately 165 kV/cm. The injector's pulse length should be over 120-ns flat top (1% energy variation) with a normalized edge emittance of less than 200 π-mm-mr. Details of the design and performance of the injector, beam line, and diagnostics will be presented.
