Abstract

A Super Tau Charm Facility (STCF) is one of the major options for the accelerator-based high energy project in China in the post-BEPCII era, and its R\&D program is underway. The proposed STCF will span center of mass energies ($\sqrt{s}$) ranging from 2 to 7 GeV with a peaking luminosity above $0.5\times 10^{35}$ cm$^{-2}$s$^{-1}$ at $\sqrt{s}=4.0$ GeV, and will provide a unique platform for tau-charm physics and hadron physics. In order to evaluate the physical potential capabilities and optimize the detector design, a fast simulation package has been developed. This package takes as inputs the response of physical objects in each sub-system of the detector including resolution, efficiency as well as related variables for the kinematic fit and the secondary vertex reconstruction algorithm. It can flexibly adjust the responses of each sub-detector system and is a critical tool for the STCF R\&D program.
