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.
