Description
Hydrodynamic tunneling of ultra-relativistic protons and their shower
through matter is an extremely important phenomenon for high-energy, high-intensity
proton accelerators with significant implication to machine protection [1,2]. Therefore, full hydrodynamic simulations of the impact of one FCC beam on solid targets were performed. We carried out simulations of FCC beam interaction with solid copper target using the energy deposition code, FLUKA and a 2D hydrodynamic code, BIG2,
iteratively. Our calculations show that although the range of a single FCC proton and
its shower is about 1.5 m in solid copper, the full 8000 FCC bunches and their shower
will penetrate up to about 250 m in solid copper due to the hydrodynamic tunneling
effect. Moreover, a substantial part of the target including the beam heated region is
melted or even evaporated, thus causing irreversible damage to the material and
possibly pollution of the accelerator environment and other equipment.
