Later the study aquired sharper focus out of the need to address the charge given to the neutrino scientific advisory group (NuSAG). NUSAG is a subpanel of HEPAP intended to advise the agencies on neutrino physics and projects.
This study is intended to help NuSAG with their new charge concerning next generation neutrino beams and detectors. The charge letter issued on March 3, 2006 can be found here .
The chairs of the study are Sally Dawson (BNL) and Hugh Montgomery (FNAL). They charged us with this job: the job
We broke up the work into various pieces. The organization is in this email
The advisory group for the study can be found here .
We set a few deadlines after the NuSAG workshop. We decided to pull an interim report together by July 15, 2006. This report would consist of individual reports addressing various parts of the charge. These reports would be delivered to NuSAG with a brief summary. At the same time NuSAG sent us a bunch of suggestions to consider for the report. To discuss these suggestions and assess our progress we met again at FNAL.
Special thanks go to Gina Rameika for the organization and anticipating various needs. We are especially grateful to Crae for coming on a weekend and making it all run smoothly.
The meeting was arranged in 3 sections: On Saturday morning we had brief reviews of the charge to the study group, and the accomplishments so far. Saturday afternoon we saw new work. We spent Sunday morning looking through the contents of the report. Gina and Milind took notes that will be used to edit the report. Agenda and presentations from Sep-16-17 meeting. here

The NuSAG report was presented by Peter Meyers. The report was approved unanimously by HEPAP. A few questions were asked concerning the size of the water Cherenkov detector that could be built at Homestake. AKM and NS raised concern about waiting for the value of theta_13 before proceeding with contruction.
At this same HEPAP meeting the DUSEL site selection by NSF was announced. This talk is by Jon Kotcher who described the process that was followed to reach the decision for Homestake.
A budget and project plan for the above is being developed.
This plan tries to get the entire 300kT as soon as possible plan-dec16-budget. plan-dec16-schedule.
Review of the cost of the cavern construction RESPEC review.
The plan is summarized in a talk to the NSAC long ranging planning meeting in Chicago, Jan. 2007. Talk in PDF.
Calculation of the beam spectra and event rates for various off-axis locations on the NuMI beamline is calculated in "Event Rates for Off Axis NuMI Experiments," B. Viren, June 8, 2006. BNL-76869-2006-IR or hep-ex/0608059
For the offaxis scenario this is a summary of the most recent beam fluxes and event rates for a nominal detector - Gina Rameika, Oct 23, 2006. This document is still preliminary. A longer document is being prepared. PDF.
The interaction rate summary tables for different NuMI off axis and WBLE beams. This also contains plots of spectra and NC single pi0 interaction spectra. This assumes no detector models.

There is an associated website with many more spectra plotted WEBSITE. These can be selected and viewed in your browser.
Christine Lewis prepared a host of plots during the study that led to the writing of hep-ph/0607177. These plots are here. http://www.phy.bnl.gov/~clewis She has attempted to label each plot with the assumptions and parameters used.
Mark Dierckxsens prepared a set of sensitivity plots for the final report. These plots were done with the final detector performance numbers from work of the StonyBrook UNO group and with a beam from FNAL using 120 GeV protons. These plots and spectra can be found at Mark's plots If something is unclear please contact us (firstname.lastname@example.org) and we will provide further information.

E. Here is a a report on liquid argon detectors focused on the R&D needed to build and cost a large detector -- 50-100 kt if that is what is required to do the science. NUSAG asked for an R&D plan - what technical progress must be made and how long do you plan for each step to take. And an idea of the cost of the R&D plan and estimates of the cost of the full scale detector if either of these costs is available. -- This summary report was produced by Steve Pordes Oct 23, 2006. report.
