Synchrotron Radiation Monitor for Beam Energy Measurements at the European XFEL | |
|
||
| Monitoring of the electron beam energies after the various accelerating sections of the European XFEL is essential for an optimal beam delivery system. Synchrotron radiation that is emitted in the dispersive section of the magnetic chicanes employed for longitudinal bunch compression can be used to determine the energy spectrum of the electron bunches. At European XFEL, vacuum chambers with an aperture of 400 mm will be installed for flexible operation of different bunch compression scenarios. Therefore, the in-vacuum mirror deflecting the visible light through a vacuum window to a camera is located on a motor driven carrier. An additional mover allows an angular adjustment of the mirror. In this paper we report on the conceptual design of the synchrotron monitor. Results obtained with a prototype setup in the laboratory are presented and several options for the synchrotron light detection are discussed. | ||
