**_Background_**
**_Beamline / Project / Activity description_**
The EIS-TIMEX beamline is designed for time-resolved (< 100 fs) experiments on light-excited condensed matter by using the FERMI FEL in the 1.7-80 nm wavelength range and a Ti:Sa fs-laser (260-800nm) as synchronized and fully coherent sources for pump-probe experiments. Main research activities include the study of condensed matter under non-equilibrium conditions, both in high-energy density regimes and below the damage threshold, as well as nonlinear effects in materials (stimulated emission, absorption saturation, spectral broadening, sum frequency or second harmonic generation) in the extreme ultraviolet energy range.
Time-resolved transmission absorption spectroscopy in the extreme ultraviolet range is the main technique at the beamline. Scattering techniques and other time-resolved spectroscopies are also available, preferably in combination with the EUV spectrometer "WEST" positioned downstream of the experimental chamber. Pilot ultrafast electron diffraction experiments were successfully carried out using the FEL as a pump.
More recently, the beamline has been used for investigating the electronic ultrafast response of functional materials and chemical compounds exposed to sub-ps light pulses. Additional classes of novel experiments include activating and monitoring slow molecular vibrational modes through combined FEL and fs-laser pulses, as well as impulsive stimulated x-ray Raman scattering in materials. In November 2023, unprecedented amplified spontaneous emission experiments from high pressure gases were carried out using a novel experimental set-up
