Analysis of feasibility of a FEL operation by radiation from relativistic electrons channeled tal in a crystal slab |
| |
Abstract: | In this paper, we study the single-particel trajectories and stable condition of relativistic electrons in a crystal slab, using the continum model proposed by Gemmell D.S. The angular spectrum of spontaneous emission from relativistic electrons in a crystal is derived, and the result shows that the coherent radiation from relativistic electrons channeled in a crystal is possible. |

Keywords: | channel-radiation continum model screened Coulomb potential free-electron lasers |
