Calibration of the forward CMS hadron calorimeters in situ by the LHC beam is
proposed. Simulations show that bent crystal channeling technique is feasible
at the LHC, and report the experience of IHEP Protvino in bending 70 GeV
protons by 9 degrees (150 mrad) during 10 years in 1994-2004 experiments.
Practical realization of calibration scheme based on simulations and previous
experience is proposed.Comment: Presented at CARE-HHH-APD Mini-Workshop on Crystal Collimation in
