FLUKA simulations of inelastic beam-gas IR1 and IR5, 6.5 TeV
- FLUKA model March 2015 extending into the arc.
- Magnetic fields for squeezed optics, beta*= 80 cm, 6.5 TeV. Including 145 urad crossing angle
- beam-gas events sampled homogenously along ideal trajectory between z=22.6 m and z=546.6 m
- inelastic interaction on gas atom forced at starting position
- no biasing used
- FLUKA geometry by L. Esposito, modified by R.Kwee
