FLUKA simulations of inelastic beam-gas IR1 and IR5, 3.5 TeV

beam-gas events sampled homogenously along ideal trajectory between z=22.6 m and z=149.6 m
inelastic interaction on gas atom forced at starting position
no biasing used
FLUKA geometry by F. Cerutti, V. Boccone and A. Mereghetti, modified by R. Bruce
