Notes:
(1) NUMI Numbers provided by Jorge Morfin. Assume NUMI-year -> 3 x 10**20 POT
(2) Fermilab Debuncher numbers provided by Steve Geer. CC rates assume CC/QE rate = 3.5
(3) CERN AD Numbers provided by Sergio Navas. For a more detailed table click HERE Note that the AD rate is low since antihydrogen running requires a slow repetition rate (60 secs or so). In the absense of antihydrogen running the rates could increase by a factor of ~25.
(4) Fermilab Booster Numbers provided by Ray Stefanski. A Booster (MiniBooNE)-year corresponds to 5 x 10**20 POT. The distance from the target to the new hall is assumed to be 250m ... could be shorter (100m ?) if more rate required.
