Bent silicon crystals installed in the betatron cleaning insertion of the CERN Large Hadron Collider (LHC) were exposed to the LHC 450 GeV/c and 6500 GeV/c stored proton and a channeling of 6500 GeV/c protons was observed in the particle accelerator. A strong reduction of beam losses due to nuclear inelastic interactions in the aligned crystal in comparison with its amorphous orientation was detected. The loss reduction value was about 24. Thus, the results show that deflection of particles by a bent crystal due to channeling is effective for this record particle energy.
