Simulation of hydrodynamic tunneling induced by high-energy proton beam in copper by coupling computer codes
/ Nie, Y (CERN) ; Fichera, C (CERN) ; Mettler, L (CERN) ; Carra, F (CERN) ; Schmidt, R (CERN) ; Tahir, N A (Darmstadt, GSI) ; Bertarelli, A (CERN) ; Wollmann, D (CERN)
The design of machine protection systems for high-energy accelerators with high-intensity beams requires analyzing a large number of failures leading to beam loss. One of the most serious failures is an accidental impact of a large number of bunches at one location, for example, due to a deflection of the particle beams by the extraction kicker magnets with the wrong strength. [...]

Review of hydrodynamic tunneling issues in high power particle accelerators
/ Tahir, N A (Darmstadt, GSI) ; Burkart, F (CERN) ; Schmidt, R (CERN) ; Shutov, A (IPCP, Chernogolovka) ; Piriz, A R (Castilla-La Mancha U.)
Full impact of one Large Hadron Collider (LHC) 7 TeV proton beam on solid targets made of different materials including copper and carbon, was simulated using an energy deposition code, FLUKA and a two-dimensional hydrodynamic code, BIG2, iteratively. These studies showed that the penetration depth of the entire beam comprised of 2808 proton bunches significantly increases due to a phenomenon named hydrodynamic tunneling of the protons and the shower.

A future circular collider (FCC) has been proposed as a post-Large Hadron Collider accelerator, to explore particle physics in unprecedented energy ranges. The FCC is a circular collider in a tunnel with a circumference of 80–100 km. [...]

Simulations of beam-matter interaction experiments at the CERN HiRadMat facility and prospects of high-energy-density physics research

In a recent publication [Schmidt , Phys. Plasmas 21, 080701 (2014)PHPAEN1070-664X10.1063/1.4892960], we reported results on beam-target interaction experiments that have been carried out at the CERN HiRadMat (High Radiation to Materials) facility using extended solid copper cylindrical targets that were irradiated with a 440-GeV proton beam delivered by the Super Proton Synchrotron (SPS).

First experimental evidence of hydrodynamic tunneling of ultra–relativistic protons in extended solid copper target at the CERN HiRadMat facility
/ Schmidt, R (CERN) ; Sancho, J Blanco (CERN) ; Burkart, F (CERN ; Frankfurt U.) ; Grenier, D (CERN) ; Wollmann, D (CERN) ; Tahir, N A (Darmstadt, GSI) ; Shutov, A (IPCP, Chernogolovka) ; Piriz, A R (Castilla-La Mancha U.)
A novel experiment has been performed at the CERN HiRadMat test facility to study the impact of the 440 GeV proton beam generated by the Super Proton Synchrotron on extended solid copper cylindrical targets. Substantial hydrodynamic tunneling of the protons in the target material has been observed that leads to significant lengthening of the projectile range, which confirms our previous theoretical predictions [N. [...]

Results of an Experiment on Hydrodynamic Tunneling at the SPS HiRadMat High Intensity Proton Facility

To predict the damage for a catastrophic failure of the protections systems for the LHC when operating with beams storing 362 MJ, simulation studies of the impact of an LHC beam on targets were performed. Firstly, the energy deposition of the first bunches in a target with FLUKA is calculated. [...]
