Computer simulations of fast particle propagation through straight and bent nanotubes

We developed a new approach to the problem of channeling of charged particles in a nanotube rope with account taken of the incoherent scattering of particles on substance electrons and thermally vibrating atoms. We present the results of computer simulations of the spatial and angular distribution of ultra-relativistic particles channeled in straight and bent nanotubes and estimate possibilities of governing high-energy beams with nanotubes.
