Outline of Final Research Achievements

We develop the Time Projection Chamber "HypTPC". The main goal of this research is to improve the high rate capability of TPC more than 10＾7 Hz. We use the Gas Electron Multiplier (GEM) for the electron amplification. Here, we developed the new type GEM called as "Mask-GEM". In case of this "Mask-GEM" system, we can mask only the beam trajectory region. After installing the "Mask-GEM" to HypTPC, we carried out the test experiment at ELPH by using positron beam. Then, we confirmed that "Mask-GEM" worked well. In July of 2018, we will do the final test experiment at HIMAC by using proton beam.
