Readiness

 We are well along in preparation:

 We have two different physics-based beam simulations and

the standard GEANT4 detector simulation.

 Track, shower, and vertex finding algorithms are well

advanced.

 We have two very different, but equally powerful, νe

identification algorithms, library matching and neural net, and a likelihood-based νµ identification algorithm.

 We have had one successful data challenge and are

planning another, which will include the full near detector- far detector extrapolation.

 We have established a set of rules for blind analyses.

NuMI Beam

 Good progress toward final high intensity configuration.  Metric = (Design

+ 2*Base)/3

 FY14 metric =

3.24 x 1020 pot

 FY15 metric =

3.62 x 1020 pot

 NOνA nominal year

= 6 x 1020 pot

Shutdown

Plans for First Results

 Data up to the shutdown.  Analysis complete November-December 2014  How much data?

 Beam projection is 1.9 x 1020 pot.  Average mass is 11 kt  Efficiency = 80% for water leaks and other teething problems.  = 1.2 x 1020 pot equivalent or 20% of a nominal NOνA year.

 In a nominal NOνA year we expect about 15 νe events x/÷ 2

depending on the physics parameters and about an equal background, half from misidentification and half from cosmic

• rays. So we would expect about 3 signal events with 3

background.
