在现代高能物理实验中，时间投影室是个非常重要的测量粒子径迹的装置，对实验的成功起着重要的不可或缺的贡献。新型的微结构探测器（Micro-Pattern Gas Detector）正在取代多丝正比室成为时间投影室像素读出探测器的首选，其中最具代表性的就是MicroMegas（MICRO-MEsh GAseous Structure）探测器。本项目通过研制读出端盖为50cm×50cm的Bulk MicroMegas探测器的时间投影室的样品，掌握制作大面积Bulk MicroMegas探测器研制的关键技术，通过测试研究各种因素对Bulk MicroMegas探测器的影响，为其今后应用到国内外大科学装置做准备。

In modern high energy physics experiments, Time Project Chamber is the key device for measuring the particle track, and plays an indispensable role for the success of the experiments. The new model of Micro-Pattern Gas Detector, represented by the MicroMegas (MICRO-MEsh GAseous Structure) detector, has become the first choice for Time Project Chamber readout detector, replacing the Multi-wire Proportional Chamber. This application aims at R&D of Time Project Chamber sample by manufacturing 50cm×50cm large-area Bulk MicroMegas detector as front-end detector and developing the key technologies for large-area Bulk MicroMegas detector in general. Furthermore, this application will also examine the influences of various factors on the Bulk MicroMegas detector in order to prepare it ready for future applications in large scientific facilities both domestic and international.
