At present time Budker INP is developing a Super Charm-Tau factory project, which consists of a high-luminosity collider with the luminosity of $10^{35}$,cm$^{-2}$s$^{-1}$ and a universal magnetic detector. The tracking system of the detector will comprise of an Inner Tracker (IT) and a Drift Chamber (DC). One of the options for IT is Time Projection Chamber (TPC). The advantages of the TPC are high spatial resolution and particle identification capabilities by registration of dE/dx losses. However, using a Time Projection Chamber implies serious challenges. For example, the TPC have to simultaneously deal with tracks from several thousands events and maintain the enormous data rate. This work describes the results of the Monte-Carlo studies of the transport characteristics in various gas mixtures proposed for TPC. Besides of this, the simulation of the ion back flow and its effect on spatial resolution will be reported.

时间投影室作为 BINP Super Charm-T​​au 工厂的内部跟踪器

目前 Budker INP 正在开发一个 Super Charm-T​​au 工厂项目,该项目由一个高亮度对撞机组成,亮度为 $10^{35}$,cm$^{-2}$s$^{-1}$和通用磁性探测器。探测器的跟踪系统将由内部跟踪器 (IT) 和漂移室 (DC) 组成。IT 的选项之一是时间投影室 (TPC)。TPC 的优点是通过注册 dE/dx 损失具有高空间分辨率和粒子识别能力。然而,使用时间投影室意味着严峻的挑战。例如,TPC 必须同时处理来自数千个事件的轨迹并保持巨大的数据速率。这项工作描述了为 TPC 提出的各种气体混合物中传输特性的蒙特卡罗研究结果。除此之外,
