Steering of charged particle trajectories by a bent crystal

Abstract The first experimental evidence has been obtained for steering of charged particle trajectories by a bent silicon crystal. The investigation has been performed at the Laboratory of High Energies, JINR. In the process of planar channeling, an 8.4 GeV proton beam has been deflected up to 26 mrad relative to the incident beam direction. This corresponds to a bending radius of 38 cm. The effective transverse component of the electric field acting on the proton beam is equal to 240 MV/cm. This is equivalent to a magnetic field of 81 T.
