Outline of Final Research Achievements |
An extremely light material tracking detector is essential in order to perform the muon-to-electron conversion search experiment which is supposed to have an excellent sensitivity to the new physics beyond the Standard Model. As such an extremely light material tracker, 20-micron-thick straw tube made by polymer film was developed. By using this straw tube, straw chamber tracker was assembled. This straw is formed by ultra-sonic welding technique which enables straw to be vacuum compatible. The vacuum compatibility was confirmed by the prototype tracker which uses this newly developed straw tubes. The electron-beam irradiation test was also conducted in order to estimate the detector performances such as spatial resolution and detection efficiency. Good enough performances for the muon-to-electron conversion experiment is achieved.
