在未来的线性e+e−对撞机的探测器中运行的时间投影室（TPC），与以前使用的传统的基于垫线的系统相比，将需要一个非常先进的读出概念。LCTPC合作研究了基于微模式气体探测器（即GEMs和Micromegas）的TPC读出系统的前景，该系统与衬垫或底层阳极平面上的CMOS相结合。在小型TPC原型室中，对于高达66cm的漂移距离，证明了优于σ⊥=100μm的分辨率。未来，研发工作将集中在大表面读出系统的技术实现上，旨在为未来TPC的读出模块开发技术概念。一个直径为77厘米的大型TPC原型已经被建造用于计划的研究。它是DESY电子束测试基础设施的一部分。2008年12月和2009年期间，Micromegas和GEM原型模块的第一次测试光束操作取得了可喜的结果。
A Time Projection Chamber (TPC), operated in a detector at a future linear e+e−collider, will require a significantly advanced readout concept compared to the traditional pad-wire-based systems used previously. The LCTPC collaboration studies the prospects of TPC readout systems based on Micro-Pattern Gas Detectors, namely GEMs and Micromegas, in combination with pads or a CMOS on the underlying anode plane. In small TPC prototype chambers, resolutions of better than σ⊥=100μm were demonstrated for drift distances of up to 66cm. In the future, the R&D efforts will focus on the technical realization of large-surface readout systems with the aim to develop a technical concept for a readout module of a future TPC. A large TPC prototype with a diameter of 77cm has been constructed for the planned studies. It is part of a test beam infrastructure at the electron test beam at DESY. First test beam operations with Micromegas and GEM based prototype modules in December 2008 and during 2009 gave promising results.
