英文摘要	In this paper the new endcap Time-of-Flight system (ETOF) of BESIII experiment at the IHEP is described. The new detector module is composed of multi-gap resistive plate chamber (MRPC) with the gas mixture 90% Freon+5% SF6+5% iso-C4H10. The whole system including the detectors, the gas system, the high voltage (HV) system, the readout electronics system is described. Finally the installation and commissioning of the whole system is introduced briefly. After the calibration with Bhabha events, the very promising time resolutions of 69 and 60 ps for one-end and two-ends of MRPCs are obtained. The average detection efficiency of two-ends is about 97.5%.
