Two bent crystals have been installed in the Large Hadron Collider (LHC) for crystal collimation studies of horizontal and vertical halos, with proton and ion beams at energies close to 7*Z TeV. In addition to demonstrating the feasibility of crystal channeling at these unprecedented beam energies, these tests are targeted at addressing specific beam collimation issues at the LHC and its High...

The UA9 experiment is investigating the feasibility of crystal-assisted collimation for high-energy hadron colliders. A crucial milestone towards this goal is the characterization of single-pass response of crystals with high-energy hadron beams. At CERN, this is done by using beams from the Super Proton Synchrotron (SPS) extracted at 400 GeV/c in the H8 extraction line for fixed-target...

The process of multiple scattering of high energy protons in a silicon crystal at its amorphous orientation was studied by simulation of proton trajectories in the model of binary collisions and by simulation of the sequences of proton collisions with atoms when their impact paramters are randomly and uniformly distributed on the symmetry cell for a given crystallography direction. The value...

Channeling in bent crystals is more and more frequently considered as an option for collimating high-energy beams. The installation of crystals in the LHC, having taken place during this past year, aims at demonstrating the feasibility of multi-stage crystal-assisted collimation and possibly improving cleaning efficiency [1]. Energy deposition studies in the LHC are routinely performed with...

A routine has been developed to simulate interactions of protons with bent crystals in the collimation version of SixTrack. This routine is optimized in view of producing high-statistics tracking simulations for the highly efficient LHC collimation system. The routine has recently been reviewed after detailed comparison with experimental data, benchmark with other codes and improved modelling...
