摘要：

We propose to use channeling radiation (CR) from relativistic electrons as a source of high energy twisted photons in the MeV range. We calculate numerically the orbital angular momentum (OAM) of radiation produced by electrons with the energies 155 divided by 2500 MeV for the axial and planar channeling in the thin Si crystal. We obtain that the average OAM of CR in this case is approximately 1 divided by 6h per photon with the photon energies about 1 divided by 2 MeV. (C) 2018 Elsevier B.V. All rights reserved.
