2. Project Description
This proposal requests funding to complete the design and engineering for a two location neutrino oscillation experiment at the Braidwood, Illinois site to level needed for submitting a full proposal in about a year.
Neutrino oscillations are one of key areas of particle physics research and, with the confirmation of the solar and atmospheric anomalies by terrestrial experiments, this area has moved toward precision measurements to map out the neutrino mixing matrix and neutrino mass hierarchy.
Reactor experiments hold the promise of unambiguously determining the 13 mixing angle which as yet has been unobserved. The size of this angle is key to developing models of neutrino mass and mixing.
A well designed two location reactor experiment, such as Braidwood, will be sensitive to sin2213 at the level of This precision is necessary, as outlined in the APS Neutrino Study, both for furthering the knowledge of oscillation phenomena but also for making future plans to attack the mass hierarchy and CP violation in the neutrino sector.
The Braidwood site is ideal for the 13 measurement and also has the unique potential to make a precise measurement of the weak mixing angle sin2W. ( More to be added on site advantages …………
The reactor company, Excelon, at Braidwood has been cooperative in preparing our initial studies and is ready to move towards submission of a full proposal for the experiment.
A reactor experiment can be timely and cost effective for doing this physics since these neutrino sources exist and the needed detectors can be of modest size and complexity.
The proposed funding includes: 1) funds to do a complete civil engineering study and cost estimate ready for putting out to bid, 2) funds for detector engineering that will bring this to the level needed for a full proposal, and 3) detector component R&D especially for Gd scintiallator.

Current NSF Grant:  NSF-PHY    Research in Elementary Particle Physics  $XXXXX
Results from Prior Support: The Columbia group has mainly been working on the MiniBooNE experiment for the last four years.  Prof. Conrad is co-spokesperson for the experiment.  MiniBooNE is a low energy neutrino experiment using the Fermilab 8 GeV proton booster accelerator.  The experiment is set up to search for neutrino oscillation through numu disappearance and nue appearance in the region of the LSND anomaly  and to make precise measurements of neutrino cross sections. Data taking started two years ago and is continuing.  Preliminary results\ref{} have been presented on how well the data distributions agree with expectations and first neutrino oscillation results are expected in 2005.  In addition, the group has continued data analysis on NuTeV experiment.  New results were presented on structure functions\ref{} including a new NLO analysis of the strange quark sea\ref{} and on updated information on the weak mixing angle.
Proposed work for this grant:
The group has, over the past year, worked closely on the reactor site for the experiment and plans to continue an active role in the team supervising the civil construction engineering.
Building on the past work for MiniBooNE, the Columbia group will investigate phototubes for the neutrino detectors.  The group has been in contact with several photoube companies and plans to obtain samples of various tubes.  Of particular importance is to evaluate the tubes for noise and radioactivity along with determining the useable photocathode coverage. 
In addition, the group is involved with the VSPLAT program which plans to upgrade a small Gd-loader scintillator detector to measure spallation rates and energies by cosmic ray muons at depths appropriate for a reactor neutrino oscillation experiment.  This will give accurate information for design work and in the end be useful for analyzing the actual oscillation data.
