CBETA, currently under construction, is a 4-pass, 40mA 150MeV ERL based on the proven Cornell ERL injector chain mated with an FFAG loop. The Cornell ERL injector program, originally intended for a large scale X-Ray light source, has been under development and operated for over 10 years. The status of the Cornell ERL injector is reviewed and its parameters compared with the challenges presented by the requirements for CBETA operation. The injector consists of a high voltage DC photocathode gun, a normal conducting buncher cavity, the superconducting injector cryomodule, followed by a splitter magnet that can transport the beam into either a diagnostics beamline or merge the beam into the CBETA ERL loop. The current status of the Cornell DC gun development program and its history will be reviewed. The performance of the injector cryomodule, capable of accelerating beams to 15MeV, will be discussed with a focus on the lessons learned from its operation. Finally the diagnostics beamline and the merger will be detailed along with the latest results from our low emittance beam studies.
