Steering of multi-MeV positron beam by a curved crystal

We observe positron bending by a crystal lattice, presumably being guided by channeling phenomenon, deflecting the beam by about 10 milliradian over a length of 1 mm of Silicon. This technique may lead to the use of channeling effect for particle beams steering at energies below 1 GeV, for the purpose of producing beams of low emittance with enhanced stability for medical and biological applications.
