Effects of high-energy intense multi-bunches proton beam on materials

• A novel method for coupled simulations of HE particle beam effects on structures.
• Multi-physics problem approach.
• Integration of Monte-Carlo based particle physics and explicit FE numerical models.
• Analysis of high energy deposition shockwaves.
• Numerical prediction of material change of phase and damage.

The prediction of material response in case of interaction with successive high energy proton bunches requires new tools and multidisciplinary approaches. The impact leads the propagation of shock-waves, which travels through the hit component causing a substantial density reduction and the appearance of tunneling effect along the beam direction. For taking into account this effect, an automatic procedure, consisting in coupling FLUKA Monte-Carlo and FE LS-DYNA codes, is developed. The case study consists of the accidental loss of 60 bunches of one of the 7 TeV proton beams of the Large Hadron Collider (CERN) on a tungsten collimator.
