[DUSELScience] NOvA Results

[Milind Diwan]

Dear Marvin and Earl:

The results obtained by MINOS are clearly wonderful.
As you know I am a collaborator and know the quality of the result.

The cost of the NUMI beamline is well known to be $120 M. This included
all the development of the horns and target. The NUMI beamline is also
~1 km  in length.

A new beamline to a DUSEL site can build up on the technology developed 
for NUMI and also it need not be as long as NUMI since the science is
now known to be at lower energies.

The approximate cost of a new beamline will be developed in
the new long baseline study that was launched last month.
The first meeting of that study was on March 6-7. And the talks were 
posted at

http://www.fnal.gov/directorate/DirReviews/Neutrino_Wrkshp.html

As you can see from these talks, a new beamline is entirely
possible at FNAL and is likely to come in well under the NUMI cost.

As you also know a new beamline is very likely needed for the much 
higher radiation environment of a greatly more intense beam.

It will be wonderful to have your participation in this study so that
we can understand  the basis of your cost estimate and the estimate that
will result from this study.

I will include you on the email distribution list for this study
and will look forward to your future participation.

regards,
Milind Diwan
