Diamond sensors for hard X‐ray energy and position resolving measurements at the European XFEL

open access: yesJournal of Synchrotron Radiation, Volume 31, Issue 5, Page 1029-1036, September 2024.
Diamond sensors have been developed and tested for operation with high‐energy X‐ray beams at the European XFEL.The diagnostics of X‐ray beam properties has a critical importance at the European X‐ray Free‐Electron Laser facility. Besides existing diagnostic components, utilization of a diamond sensor was proposed to achieve radiation‐hard, non‐invasive
