Detailed studies have been carried out over the past few years to study the full impact of the LHC beam on solid targets made of different materials including copper and graphite. It has been found that energy deposited by first few tens of proton bunches generates enough pressure in the material that leads to an outgoing radial shock wave which depletes the density in the beam heated region. The protons that are delivered in subsequent bunches therefore penetrate much deeper into the target. The simulations have shown that in a solid copper target the protons will penetrate up to 35 m and the target will be seriously damaged. In case of a solid graphite target the penetration depth is about 10 m. Similar studies have also been carried out considering full impact of the SPS beam on copper and tungsten targets. An interesting outcome of this study is that one may also study High Energy Density Physics at these impressive facilities.
