| 英文摘要 | The COMET experiment at J-PARC aims to search for a lepton-flavour violating process of muon to electron conversion in a muonic atom, mu-e conversion, with a branching-ratio sensitivity of better than 10(-16), 4 orders of magnitude better than the present limit, in order to explore the parameter region predicted by most of well-motivated theoretical models beyond the Standard Model. The need for this sensitivity places several stringent requirements on the detector development. The experiment requires to detect the monochromatic electron of 105 MeV, the momentum resolution is primarily limited by the multiple scattering effect for this momentum region. Thus we need the very light material detector in order to achieve an excellent momentum resolution, better than 2%, for 100 MeV region. In order to fulfil such a requirement, the thin-wall straw-tube planar tracker has been developed by an extremely light material which is operational in vacuum. The COMET straw tracker consists of 9.8 mm diameter straw tube, longer than 1 m length, with 20-mu m-thick Mylar foil and 70-nm-thick aluminium deposition. Currently even thinner and smaller, 12 mu m thick and 5 mm diameter, straw is under development by the ultrasonic welding technique. (C) 2016 Elsevier B.V. All rights reserved. |
