CNGS Neutrino fluxes at GranSasso

• Full FLUKA simulation of the CNGS neutrino beam
• Meson production in the target
• Reinteraction
• Transport in horn/reflector magnetic fields
• Decay , incl. polarization and matrix elements
• Beam dump/ muon pits
• Available version on the web 2003
• New 2005 version next days ( maybe already
  there). Updates
• Details of target supports/ target tube
• Details on materials along the path windows,
  TBID, air segments
• Important for other studies shielding, supports

Also from the CNGS web page, following ? Beam
performance ? Neutrino beam at Gran Sasso
what

• Tables of neutrino fluxes as a function of energy
  for ?e, ?µ and anti- ?e, ?µ
• Integrated neutrino CC event rate for an
  isoscalar target (cross sections from NUX-FLUKA)
• Plots of neutrino fluxes and rates
• N-tuples with neutrino generation history
  (neutrino id, energy, position, parent meson,
  decay point etc )
