The first pro­to­type crab cav­ity with the 4-rod geom­e­try has un­der­gone sur­face treat­ment and cold test­ing. Due to the com­plex geom­e­try and unique fab­ri­ca­tion pro­ce­dure, RF val­i­da­tion of the field at be­yond the nom­i­nal op­er­at­ing volt­age at a suf­fi­ciently high Q0 is an im­por­tant pre-req­ui­ste. Pre­lim­i­nary re­sults of the first cold tests are pre­sented along with cav­ity per­for­mance at dif­fer­ent stages of the cav­ity pro­cess­ing is de­scribed.
