| Outline of Final Research Achievements |
In this research program, we aimed to develop the detector which can explore the phenomenon in the new elementary particle standard model caused by higher energy than tera-electron-volt. This can be realized investigating the known particle's phenomenon precisely. However, known phenomenon at mega-electron-volt must be investigated carefully with a low material detector because the particle trajectory can be disrupted easily due to the multiple coulomb scattering. In this research program, extremely thin-wall straw, which is operational in vacuum, was enabled by ultra-sonic welding technique. This thin-wall straw was equipped as a tracking detector, and the detection performances were confirmed with 105 MeV electron beam in the vacuum environment. By this result, the detector R&D for COMET Phase-I was completed. And a new straw, 12 micron-thick and 5mm rad., was also enabled by new technique. Four more straw stations would be constructed to perform the COMET Phase-II experiment.
