By optimizing the horn focusing system, modest increases can be achieved in the low-energy part (1 GeV region) of the neutrino spectrum at NuMI, compared to the existing NuMI LE (low energy) tune. Variations using the existing horn system would be inexpensive. For a new horn design, by looking at the WBS elements for the LBNE old reference design, one could guess that the development, prototyping and construction of new horns, power supply, strip-lines and target, when done under project accounting, would likely increase costs a couple 10's of millions of dollars TPC.
