Seminar topic: “X-ray Free-Electron Lasers in Hamburg”
Speaker: M.V. Yurkov (DESY, JINR)
Abstract:
Two large-scale x-ray free electron laser (XFEL) facilities, FLASH and European XFEL, successfully operate in Hamburg. Peak and average brightness of XFEL radiation exceeds by eight and four orders of magnitude relevant values of modern SR sources. Potential to generate ultra-short pulses with sub-femtosecond duration allows investigation of dynamical process in matter on an atomic time scale. Deutsches Elektronen Synchrotron (DESY) holds world leadership in the development of x-ray FELs. TESLA Test Facility FEL produced first light in 2000. First dedicated XFEL user facility FLASH (Free-eLectron LAser in Hamburg) started operation in 2005. Presently FLASH consists of ten user stations, two x-ray undulator lines, far-infrared undulator (designed by JINR), and optical lasers for conducting pump-probe experiments. X-ray radiation is produced by 1.25 GeV electron beam from superconducting accelerator. European XFEL started operation in 2017. Three undulator beamlines (500 m total length) are driven by 17.5 GeV superconducting accelerator. This report presents an overview of current status of XFEL facilities and plans of future developments.
