Simultaneous Operation of Two Soft X-Ray Free-Electron Lasers Driven by One Linear Accelerator
ddc:530
Extreme-ultraviolet to x-ray free-electron lasers (FELs) in operation for scientific applications are up to now single-user facilities. While most FELs generate around 100 photon pulses per second, FLASH at DESY can deliver almost two orders of magnitude more pulses in this time span due to its superconducting accelerator technology.
