A prototype of the high average current polarized electron funneling gun as ERL-FFAG based eRHIC injector has built at BNL. In last year, we generated two beams from GaAs photocathodes by CW green laser and combined by a switched combiner field. We observed the combined beams on a YAG crystal ,measured the photocurrent and cathode lifetime by a Faraday cup. In this paper, we will describe the major components of the gun and beam line optics. We will also discuss the recent beam test results and high voltage conditioning results.
