Undulator commissioning by characterization of radiation in x-ray free electron lasers
In x-ray free electron lasers (XFELs) where a long undulator composed of many segments is installed, there exist a number of error sources to reduce the FEL gain such as the trajectory error, K value discrepancy, and phase mismatch, which are related to the segmented-undulator structure. Undulator c...
