	The LHC is the world's largest and highest energy accelerator. Two counter-rotating beams can be accelerated up to 7 TeV and kept colliding for several hours. The energy stored in each beam is up to 362MJ, enough to melt 500 kg of copper. A fast loss of a small fraction of the beam can cause damage to a superconducting coil in a magnet. Primary beam collimators, one of the most robust parts of the machine protection, can be damaged with about 5% of the beam. An accident involving the entire beam is very unlikely but cannot be fully excluded. Understanding the consequences of such accidents is fundamental for the machine protection. Detailed numerical simulations have been carried out to assess the damage caused by full LHC beam impact on solid Cu and C cylinders. The energy loss of the protons is calculated with the FLUKA code and this data is used as input to a 2D hydrodynamic code BIG2, to study the thermodynamic and hydrodynamic response of the material. Since the target parameters change substantially during the time of impact, a new approach of running the two codes iteratively, has been developed. In this paper the results are presented and compared with the previous studies.

High Energy Density (HED) Physics spans over wide areas of basic and applied physics. Strongly bunched high quality intense particle beams are an excellent tool to generate HED matter in the laboratory. Over the past decade, we have carried out extensive theoretical work to design HED physics experiments for the future FAIR facility at Darmstadt. These experiments will be carried out to study the equation-of-state properties of HED matter*, interiors of the Giant planets**, growth of hydrodynamic instabilities in solids and ideal fluids in the linear and the non-linear regimes*** as well as the solid constitutive properties of materials of interest under dynamic conditions.
