标题： Resolution Studies of GEM/Timepix Detector with 5 GeV electrons

摘要： 这项贡献研究了一个TPC读出原型，该原型采用高度像素化的CMOS ASIC，这是ILC带电粒子跟踪的一种选项。 一个三重GEM堆栈与TimePix和MediPix2芯片（像素尺寸为55$\times$55 $\mu m^2$）连接，并使用5 GeV电子对其读出特性进行了研究。 通过不同的簇算法，确定了簇中心重建的空间分辨率作为漂移距离的函数，并与蒙特卡罗预测进行了比较。 显示英文摘要

摘要： This contribution investigates a prototype of a TPC readout with a highly pixelated CMOS ASIC, which is an option for charged particles tracking of the ILC. A triple GEM stack was joined with a TimePix and MediPix2 chip (pixel size of 55$\times$55 $\mu m^2$) and its readout properties were investigated with 5 GeV electrons. The spatial resolution of the cluster center reconstruction was determined as a function of drift distance using different cluster alhoritms and compared with Monte Carlo predictions.
