MuSIC施設でのミューオン素粒子物理学の研究

这项研究的目的是研发一个时间投影室，用于在MUSIC(大阪大学核物理研究中心)搜索μ-GT；eee。今年的计划是：建立一个时间投影室原型；测试电子读数；以及使用放射源、宇宙射线和束流测试进行测量。-建造时间投影室原型：原型的所有必要部件都已经购买。5块标准宝石箔从欧洲核子研究中心购买(由REPIC进口)。箔的有效面积为100×100 mm~2，孔洞外径为70微米，节距为140微米。燃烧室部件由REPIC制造。GEM级之间的距离为2 mm，最大漂移距离为10 mm。由于部件交付得很晚，组装尚未完成，我正在忙于另一项实验(PSI的AlCap，这是我的研究生论文所需的工作)。-电子读数和其他测量的测试：由于组装延迟，尚未进行测试或测量。

The purpose of this research is R&D for a Time Projection Chamber (TPC) for a search for μ->eee at MuSIC (Research Center for Nuclear Physics, Osaka University).The plan for this year was : building a prototype TPC ; testing of electronics readout ; and measurements with radioactive sources, cosmic rays and beam tests.-Building the prototype TPC :All necessary parts for the prototype have been bought. Five standard GEM foils are bought from CERN (imported by REPIC). The foils have active area of 100x100 mm2, holes outer diameter of 70 micron and pitch of 140 micron. Chamber parts are made by REPIC. The distance between GEM stages are 2 mm, maximum drift distance is 10 mm.The assembling has not been done yet since the parts were delivered quite late, and I was busy with another experiment (AlCap at PSI, this is the work needed for my graduate thesis).-Testing of electronics readout and other measurements :As a consequence of the delayed assembling, no test or measurement has been done yet.
