  We present simulations of particle beam channeling in carbon nanotubes and
evaluate the possibilities for experimental observation of channeling effect in
straight and bent nanotubes at IHEP and LNF. Different particle species are
considered: protons of 1.3 and 70 GeV, and positrons of 0.5 GeV. Predictions
are made for the experiments, with analysis of requirements on the quality of
nanosamples and resolution of the experimental set-up. Based on Monte Carlo
simulations, the capabilities of nanotube channeling technique for particle
beam steering are discussed.
