Abstract：
Characteristics of time of flight counter wrapped with five reflective materials: tyvek, teflon, millipore, ESR and Al film is studied by test beam at BEPC linear accelerator. It includes three aspects: the time resolution, the attenuation length and the effective speed of light. Al film wrapping can give the best time resolution of 95.6±2ps. ESR wrapping can give the biggest amplitude and longest attenuation length. The effective speed of light in the scintillator bar with these 5 different reflective materials is basically the same.
