S1.00001: Physics of a long and very long baseline neutrino program Invited Speaker: I will discuss opportunities in neutrino oscillation physics using conventional high energy accelerator neutrino beams. I will first discuss the properties of the beams and the expected event rates for various concepts that are under discussion. The physics goal is to measure known oscillation parameters precisely, find the conversion of muon to electron neutrinos at accelerator energies, and discover violation of the CP symmetry in the lepton sector if it exists. With the current knowledge of neutrino parameters, we already have a good understanding of the beam power level, detector size, and the baseline needed for such an experiment. We can optimize the experimental parameters to obtain the best possible sensitivity. I will describe this optimization. In my conclusion, I will describe a possible project that takes full advantage of existing accelerator facilities at Fermilab or Brookhaven and couples the beam to a very large detector at a new deep underground science laboratory.

S1.00003: J-PARC Project in Japan Invited Speaker: From the spring of 2001 a new accelerator complex, called the J-PARC, has been under construction by the cooperation between two organizations, KEK and JAEA, where KEK is a high-energy organization and JAEA is a nuclear power organization in Japan. The main goal of the J-PARC is to accelerate and use high-power MW-class proton beams at 3 GeV and 50 GeV. The 3 GeV beams will be used for production of spallatiion neutron beams and muon beams for the study of materials and life sciences. A rapid cycle synchrotron of 25 Hz is prepared for this purpose. On the other hand, the 50 GeV beams will be used for production of intense kaon beams (for kaon factory) and neutrino beams, where the latter beams will be detected at the Superkamiokande detector located at about 300 km from the J-PARC site. The entire budget that were already approved is over 1,500 Oku Yen (about 1.3 billion dollars). Overall, two third of the construction work is completed. The anticipated completion of the construction is late 2008. In the talk I would like to present the current status of the project including accelerator construction, physics opportunities and other major issues of the project. [Preview Abstract] |
