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.

本研究的目的是在大坂大学原子核物理研究中心（MuSIC）研究μ-> γ的时间投影室（TPC）。本年度的计划是：制作TPC原型，进行电子读出测试，进行放射源、宇宙射线和束流测试。建立TPC原型：原型的所有必要部件都已购买。从欧洲核子研究中心（CERN）购买了5片标准GEM薄膜（由REPIC公司进口）。箔的有效面积为100 × 100 mm 2，孔外径为70微米，间距为140微米。腔室部件由REPIC制造。GEM平台之间的距离为2 mm，最大漂移距离为10 mm。由于零件交付得很晚，组装尚未完成，我正忙碌另一个实验（PSI的AlCap，这是我的研究生论文所需的工作）。电子读数测试和其他测量：由于组装延迟，尚未进行任何测试或测量。
