Abstract：
The Endcap TOF(ETOF)of Beijing Spectrometer(BESⅢ) consists of 2×48 pieces of trapezoidal scintillator (BC408). Its main physics goal is to reach the intrinsic time resolution of 80ps and to realize the 2σ π/k separation at momentum up to 1GeV/c. In this paper, the performance of one ETOF module under different conditions, such as with different packing material、operating voltage and shape of scintillator, is tested by the beam of 800MeV electrons at IHEP. The primary results show that the intrinsic time resolution of ETOF with Tyvek paper wrapping is between 70-90ps.
