a) Simulations Ecloud (Furman)

a) Simulations Ecloud (Furman) ecloud is observed in the FNAL MI, but it is not an operational limitation. Simulation studies (by M. Furman) have been made for higher intensities in view of neutrino program, which revealed to be almost insensitive to the beam energy.
