论文摘要
目前，Budker INP正在开发一个超级魅力的工厂项目，该项目由一个高亮度对撞机组成，其光度为$ 10^{35} $，cm $^{ - 2} $ s $ s $^{ - 1} $和一个通用磁性检测器。检测器的跟踪系统将包括内部跟踪器（IT）和漂移室（DC）。它的选择之一是时间投影室（TPC）。 TPC的优势是通过注册DE/DX损耗的高空间分辨率和粒子识别能力。但是，使用时间投影室意味着严重的挑战。例如，TPC必须同时处理数千个事件的轨道并保持巨大的数据速率。这项工作描述了针对TPC提出的各种气体混合物中运输特征的蒙特卡洛研究的结果。除此之外，还将报告对离子后流的模拟及其对空间分辨率的影响。
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.
