Grant: Subatomic Physics Envelope - Project

In this proposal, we request a grant to provide common fund contribution of the T2K Canadian group in FY2007 and FY2008.  T2K is a long-baseline neutrino experiment that will send a neutrino beam from J-PARC (Japan Proton Accelerator Research Complex), currently under construction in Tokai, to the Super-Kamiokande water Cerenkov detector located 295km away in Kamioka. The goal of the project is to determine the neutrino mixing angle theta-13 and to search for a possible non-zero CP-violating phase in the neutrino mixing matrix.  A three year detector construction and operation grant for the Canadian T2K project was funded in April 2006. The Canadian group has taken responsibility for major parts of the experiment: the time projection chambers (TPC) and fine-grained detectors (FGD) for the off-axis near detector, and the primary proton beam monitor in front of the production target.  The neutrino beamline commissioning is scheduled for April 2009, and the beam monitors, FGDs, and TPCs are all required to be ready at the time of the commissioning.The  collaboration fee is US$5000 per PhD physicist per year starting FY2007. There are 24 PhD physicists in the Canadian group. In the first two years, the collaboration fee will be used for the common projects, such as installation of the spectrometer magnet.Requested funds:FY2007 $135,000FY2008 $135,000
