Executive Summary

Fermilab is poised to significantly improve our understanding of neutrino oscillation.

The MiniBooNE experiment [1] using the Booster Neutrino Beam (BNB) will

confront the puzzling ОÐ...e oscillation results from LSND within the next year. The

MINOS experiment [2] will detect neutrinos produced by the NuMI facility in early

2005 to confirm the presumed ОÐ...Ој в†' ОÐ...П„ oscillation results from Super-Kamiokande,

and to make precision measurements of the mixing parameters. The proposed NOОÐ...A

experiment will use off-axis neutrinos from the NuMI facility to detect ОÐ...Ој в†' ОÐ...e

oscillations. The investment in accelerator upgrades described in this document will

maximize the physics reach of these experiments.

We present a three-year plan for increasing the proton intensity delivered to the 120

GeV and 8 GeV neutrino beams, with upgrades to the Linac, Booster and Main

Injector. Once the elements of this plan are completed, NuMI will accumulate

approximately 3.4E20 protons per year. The 8 GeV beamline will receive

approximately 2.2E20 protons per year. This latter estimate is highly dependent on

the performance of the Booster and other efficiency factors.

The preliminary estimate for the total cost of this plan, including 46% contingency, is
