标题： Construction and Performance of a Micro-Pattern Stereo Detector with Two Gas Electron Multipliers

摘要： 描述了尺寸为40x10 cm**2的微结构气体探测器的构造。 两个气体电子倍增箔片（GEM）提供了内部放大阶段。 使用了两层读出结构，该结构采用与GEM箔片相同的制造技术。 每一层的条带以6.7度的有效交叉角交叉，并具有406微米的间距。 探测器的性能在CERN的μ子束中进行了评估，使用硅望远镜作为参考系统。 两个正交坐标的定位分辨率分别测量为50微米和1毫米。 二维空间点的μ子探测效率达到96%。 显示英文摘要

摘要： The construction of a micro-pattern gas detector of dimensions 40x10 cm**2 is described. Two gas electron multiplier foils (GEM) provide the internal amplification stages. A two-layer readout structure was used, manufactured in the same technology as the GEM foils. The strips of each layer cross at an effective crossing angle of 6.7 degrees and have a 406 um pitch. The performance of the detector has been evaluated in a muon beam at CERN using a silicon telescope as reference system. The position resolutions of two orthogonal coordinates are measured to be 50 um and 1 mm, respectively. The muon detection efficiency for two-dimensional space points reaches 96%.
