FLASH, acronym of Free Electron LASer in Hamburg, is a superconducting particle accelerator-based soft X-ray free-electron laser located at the German national laboratory DESY in Hamburg, Germany. It can generate very powerful, ultrashort pulses (~10−14 s) of coherent radiation in the energy range from 10 eV (electronvolt) to 300 eV. It started operation for external users in the year 2005 and is... (Wikipedia)
