论文摘要
国际线性对撞机(ILC)的国际大型探测器(ILD)需要大大改进的子检测器系统以符合设想的性能。它的中央跟踪检测器是一个时间投影室(TPC),配备了Micropatern气态检测器(MPGD)读数模块。 LCTPC协作成立于2007年,旨在设计基于MPGD的TPC并构建和测试演示器模块。为此,建立了在DESY的DESY设置,自2010年以来,已经在许多成功的测试束运动中研究了四个不同的读数概念。可以证明,可以实现所需的横向和纵向空间点分辨率。同样,开发了一个新的门控概念,可以有效地消除离子的回流,同时略微降低检测器的性能。
The International Large Detector (ILD) at the International Linear Collider (ILC) requires significantly improved subdetector systems to comply with the envisioned performance. Its central tracking detector is a Time Projection Chamber (TPC) which is equipped with Micropattern Gaseous Detector (MPGD) readout modules. The LCTPC collaboration was founded in 2007 to design such a MPGD-based TPC and to build and test demonstrator modules. For this an experimental setup at DESY, Hamburg, was built, where four different readout concepts have been studied in many successful test beam campaigns since 2010. It could be demonstrated that the required transverse and longitudinal space point resolutions can be reached. Also, a new gating concept was developed that can effectively eliminate the ion backflow, while marginally degrading the performance of the detector.
