THGEM films were treated by a new chemical polishing method in this experiment. The gain and energy resolution of THGEM films were measured under different gas composition and proportion. The optimal gas selection scheme(Ar/C4H10) is obtained. Under this gas, for THGEM, by using relatively low work voltage, high gain and relatively high energy resolution could be obtained. The experimental result indicated that the highest gain is 7×10(3 )when the detector work in Ar/C4H(10 )(95%/5%).
