Matter under extreme conditions probed by a seeded free-electron-laser

Abstract

FERMI is the first user dedicated seeded free-electron-laser (FEL)\ud working in the extreme ultraviolet (XUV) and soft x-ray range. The\ud EIS-TIMEX experimental end-station was availabe to external users since\ud from the beginning of the user operation of the facility, in Dicember\ud 2012. EIS-TIMEX has been conceived to exploit the unique properties of\ud the FERMI source to study matter under extreme and metastable\ud thermodynamic conditions. We hereby report on its basic parameters and\ud applications, which includes very low jitter (i.e., high time\ud resolution) pump-probe measurements
