mu beam in AK3

[Bernhard Lauss <lauss@berkeley.edu>]

here comes my estimate

the AK3 disk is 457 mu thick  / 18 mil

   p       mean of stopping distribution
  MeV/c    mu in AK3
   36	    250
   35	    200
   34	    160
   33	    120
   32	     80
   31	     50
   30	     30

at 35 MeV/c the first mu punch through

momentum is actually scaled up by 1MeV/c
from comparing last years data and the TPC stopping distribution.
