High intensity conventional horn-focused neutrino beam produced by MW-class proton accelerator, 'superbeam', provides opportunity to further develop neutrino physics, especially long baseline (LBL) oscillation experiments. Several superbeam LBL experiments are proposed as next generation high sensitivity, high precision experiments before neutrino-factory era. Sensitivities of the experiments are one or two orders of magnitude higher than the current ones. The experiments and their physics potential are introduced.

Super muon-neutrino beams: physics reach and open questions

A report on the challenges confronting the Fermilab Linac and Booster accelerators is presented. Plans to face those challenges are discussed. Historically, the Linac/Booster system has served only as an injector for the relatively low repetition rate Main Ring synchrotron. With construction of an 8 GeV target station for the 5 Hz MiniBooNE neutrino beam and requirements for rapid multi-batch injection into the Main Injector for the NUMI/MINOS experiment, the demand for 8 GeV protons will increase more than an order of magnitude above recent high levels. To meet this challenge, enhanced ion source performance, better Booster orbit control, a beam loss collimation/localization system, and improved diagnostics are among the items being pursued. Booster beam loss reduction and control are key to the entire near future Fermilab high energy physics program.

Challenges to the Fermilab linac and Booster accelerators

This paper is a summary report of the Proton Driver design study that has recently been completed at Fermilab. It describes the design of a new 16 GeV high intensity rapid cycling synchrotron as a replacement of the present Booster. The major design goals are: (1) 1 MW beam power; (2) 1 ns (r.m.s.) bunch length. The construction will be staged. It has also an upgrade path to 4 MW.
